Some vehicles actually have a vent cut valve on the tank for that purpose. If the fuel level is too high, the valve closes from the fuel and nothing will be allowed into the EVAP system from the tank (i think only on steel tanks, but idk). Perhaps if that vehicle had such a valve, the system was being compromised by the pressure induced by the smoke machine, or perhaps the valve was faulty (again, this is assuming the tank had such a "liquid valve" in the first place).
I'm a Texan girl living in Milwaukee. One good mechanic did a first good job on my 03 Lightning. 2021- he hired goons to trouble shoot electronics. Leaving a sound system cap totally powered up running computer tests. Yes he replaced my shocks (tried hard to talk me out of Bilsteins bc "they ride stiff". Over 100mph you want them. 140mph Then)! My always 12psi boost was dropped to a depressing 8 psi and less shriek. It took me 8 mo of almost redoing wire harness myself. I had to guess at some wild jerryrigging they did. My sound system is almost 3000W peak. I was planning to pull it and all fresh wires components. Cried driving it home. I disconnected sound and capacitor everything when I saw what they did. "Hot when on" relay got very hot and started melting. I really liked front office guy I can't drill thru the firewall. See that huge red wire? I drilled it! He still blew me off as stupid. The best mechanic is your self. Or my dad. I let this mechanic work on winter beater car. How do you screw up an 05 Impala? Yes, Lightnings are complex no diagrams or parts. But the Impala? Just air vent fan? Which promptly broke. That kind of service will get you laughed out of a Texas town. Mechanic knew he had a 8-10k high budget, had it 8 weeks. He charged 2k. I said I don't want cheap I want it dead perfect. All he did right was new suspension and steering fluid leak. I am the customer you don't want to lose.
@@David5467 Yeah, I did a double-take myself. Maybe one day Steve from GamersNexus will let us know how the guy's cannister warranty/return went; give NewEgg a breather 🤣
It's amazing that the customer didn't know what was wrong with the car. Hence, it showed up in your possession to diagnose the car, you diagnose the problem, and tell him the diagnosing procedure and what causing the failure and immediately he became the expert and said you were wrong. Ray one thing you can't fix is ignorance or stupidity 🙅
Ray, early on you spotted the problem by looking at the fuel gauge. But you went through the entire process to confirm the hypothesis. Great job. Maybe he's just embarrassed, and he'll learn to stop overfilling his tank.
I feel your frustration, Ray. When you pour your heart and soul into your work, you open yourself up to mindless jerks who think nothing of crushing spirits in order to further their own ends. In this case, the customer couldn't believe that he'd made a mistake. Rather than laughing it off and learning from the experience, he kicks the first dog he sees; unfortunately, that was you. I've learned so much from your videos, and you've become a vital part of my morning routine. You have the perfect combination of technical acumen, personality, and humor that guarantees success. I hope you can shrug this off and understand that there are some real dirt bags in this world that simply can't be pleased and don't deserve another moment of your time. Goosfraba, brother.
I have been a nurse going on 25 years I have drawn one conclusion I could cure cancer stop world hunger stop wars on earth do 100 things that 1 thing I do wrong regardless of how small will be the thing my boss or other people will harp on a destroys me daily for not doing it right
I think you guys missed the mark on this one. Unto most people, a mechanic's reputation is just a hair above a used car salesman. Given the abundantly poor service from many a dealership, you can't blame them. I think the guy has had some bad experiences in the past and is fearful that most mechanics are just trying to take him for a ride. Just have to build up a rapport with the customer base to help alleviate them of these perceptions and false conclusions.
@@nottelling4828 most of the time, the stereotypical mechanics have a bad reputation, but Ray is like a king of car repair and an exception to the rule. He should showcase his channel at the shop as proof of his professionalism and dedication to doing things properly.
Wow! That was a heck of a thorough, well-thought-out, troubleshooting chain of events ! The only thing you can't fix is stupid! Outstandingly good job!
It's unfortunate that the customer was unwilling to listen, though on the other hand you've taught all of us a valuable lesson for why we should never overfill tanks.
Brilliant diagnosis; so well done to you. We can please most people most of the time but cannot please all people all of the time. The customer is not always right. Thanks for sharing.
I agree. I did tech support for years. We were taught that the customer is always right until you can prove otherwise. I personally went with, the customer experience is always unique. I knew of techs that argued with customers, telling them that what they experienced is impossible. It's not impossible, just improbable. And, customers hate hearing that the problem is caused by a user error. No one likes being told they are the problem/cause of the problem.
Normally these type of people are "KNOW ALLS" that never have achieved anything in life except riding on opportunities. You on the other hand have gone out of your way to lay the proof on the table. You are a thorough GENTLEMAN concerning your situation. Well done, you are the winner.
Another masterclass in diagnostics, well done sir! Re: the disgruntled customer; Always remember "No good deed goes unpunished." Don't take it personally. We love ya!
I was expecting that kind of a response from the customer, having all these parts replaced previously and not saying anything about it, he just needed a confirmed repair as a second opinion, made all the fuss just to not pay for your work and diagnosis, and he got what he wanted and got away with it, great work Ray, as usual.
I hate to see bad things happen to good people, but I REALLY hate to see good things happen to bad people. I hate to see people be exploitative like this, and I hate it even more when they get away with it. Disgusting.
Since this OG was a teen I have had many jobs that required interacting w the public. From being a stock boy at a neighbor's pharmacy to my last 26 years as a Psychiatric RN. I learned many lessons in my working years. When one develops expertise in a particular area allowing that expertise to, "speak for itself", is often the 1st line of defense in dealing w difficult, unreasonable & those who go so far as to question a person's motive. I'm not a gear head. I have rudimentary automotive knowledge. I cannot help but be impressed by your plain speaking, everyman approach to problem solving. The way you work & present problems keeps me instantly invested in watching. You draw me into a journey of diagnosis, challenge logic, discovery & solution. Well thought, thorough, honest, consumer advocate w accrued expertise & seemingly humble as well. You are a credit to your profession.👍🏼
Some owners just don’t take responsibility for there actions, they just don’t believe it could possibly of been them that broke their car, Unbelievable ! Thanks for another great video Ray
@@earnestp.worrell5389 If you are going to go down that path, it should read "Some owners just don't take responsibility for THEIR actions" but I wasn't going to say anything.
Which can also be caused by the complete undermining of respect for experienced trades people partly due at least from the sheer number of incompetent businesses & scammers out there. I have sympathy for both sides skilled workers deserve to be listened to & respected we also need to root out the bad actors from the industries too
My dad had a motto that he always followed. Sometimes, you have to fire a customer. Should not happen often, but every once in a while, you get one that just isn't worth keeping.
Note to self: overfilling the gas tank is worse than I thought! It's great to learn new things from you Ray. Once again, a thorough and fantastic diag that will be useful to me someday.
you see in my car being that it is a 2013 fiesta, it has the ford "easy fuel" neck which is a capless neck, I find it quite hard to over fill the tank infact if the nozzle isn't in the exact right position its just generally hard to fill the tank lol
I was thinking the exact same thing, I didn't know there was a charcoal filter in the gas tank assembly to help with the fumes and that over filling would kill it. I always just though overfilling was bad because it would cause fuel to over-spill only.
@@Bamahut The tubes connected to the gas tank, are connected to the filler neck, as long as you stop at the first click, the level of petrol will be below the connections, if you goto the trouble of over filling, looks like you can fill the level over the height of the connections, then you fill the cannister up with fuel.
Yeah,you're right, but I'm sure he has a lot of works to do on others customers cars , and sadly the bad mentality and the total lack of honesty is creepy nowadays
I paused at 8:30 to guess/comment before continuing: I would detach the evap canister first to check if it's filled with gas. I sometimes see this happen when people habitually overfill their fuel tank. And now back to our regularly scheduled video...
Same here. You'd think though the evap canister would be above the tank level and a check valve to prevent liquid from getting in. I get that evap can't do its job when tank is full, but it doesn't need to as there's no void to generate vapors to be purged.
When you are filling up your tank, how are those vapors routed into the canister vs just coming back out the nozzle? I understand the vacuum of the engine sucking off the vapors from the tank etc, but still not understanding how vapors get to the canister when filling up with gas.. Sometimes when I'm filling up my truck, the gas pumps nozzle keeps cutting off repeatedly up to a point where it seems to stop and let me finish filling up.
@@captinbeyond Then it's filling too fast. It's not the vapours that get to the canister in this case. It's when the valve opens, the fuel level is too high and it sucks raw fuel in rather than vapours.
@@captinbeyond Think of a straw in a cup, straw above the liquid line, you suck air. Straw below the liquid line, you get liquid. Overfill the gas tank and now the liquid line is too high allowing liquid to flow in place of the intended vapor. The charcoal canister is filled with many tiny charcoal pellets. The pellets absorb the gas vapor and allow fresh air to flow around them via the tank vent valve. The gas tank must vent to atmosphere except when the vehicles ECU runs the evap system test cycle. If the gas tank can’t vent it will collapse inward from the vacuum generated by the purge valve opening . When the charcoal pellets saturate with liquid they expand and turn to mush. Then there is no airflow through the canister to vent the gas tank to atmosphere. Don’t overfill your gas tank.
As my dear departed father used to say, "There is an ASS for every seat"!!! This profound statement is the result of our family owning an autobody repair shop for 64 years and dealing with a wide range of Humanoids that would wonder into our shop. Some customers have nothing between their ears and are just Jerks! As always, GREAT JOB RAY!
For sure I tried to round out my fuel cost to an even number. Click, click and another click. While this customer did not appreciate it your viewers did. I for one learned a valuable lesson and no longer try to overfill
It’s mostly cause the costumer is not educated and thinks they know what the problem is and can’t take another response. These people just waste everyone’s times the customers and the mechanics. Put your pride to side and be open to a mechanics expertise. But for these customers it’s hard cause they believe they did nothing wrong and have been too multiple shops and think they are being screwed but in fact it’s the customer really that’s causing the issue. It can be frustrating as a mechanic
Click bait "you're fired"? Your videos are awesome, no need for hyped titles to get us to watch, im subscribed and I still think you're a mechanical genius!🍺👍
I remember learning about the EVAP system in school but did not fully understand the system, but this is a perfect example of diagnostic to the system. Thank you!!!
Excellent work on the diagnosis. I've had customers throw full on temper tantrums when they find out the issue was caused by them. Nothing to do here except tell the customer you can't help them. Unfortunately, the customer will tell 1000 people how you tried to "rip them off". On the flip side, if you found something like the vent solenoid not plugged in, connected it, told them "no charge, have a great day", they'd never tell a soul. 😐
As a man who's been in the service business ( musical instruments) since 1976, I concur. It's the " no good deed goes unpunished" thing. When I've found an honest helpful carpenter, plumber, lawyer, mechanic, roofer, (you name it) I just never go anywhwere else. I think it's important to support the good folks who support you. ! Promotes that rewarding sense of comminity, where we all become friends. Friends are good to have. This man seems like a good guy who was really trying hard to help out.
The customer may not have appreciated your hard work but we sure do. I’ve done an extra top up with the fuel myself but now seeing what it can do, I will never do it again. You have helped to reduce a needless repair, thanks Ray! =]
extra top up is ok up to a point. What i do is once the fuel clicks and stops, i add a bit more just so that the dollar amount is exact. There is a time where i overfilled to get the dollar amount but the fuel would shoot out a bit. However my car over estimates the fuel and the low fuel warning light doesn't come on and since its an old car its not quite an issue and i dont run into this issue either.
Let's not forget that the tank is full. The scan tool did say tank should be 1/2 to 3/4 full for diagnostics. For all we know, evap may still work once fuel gets down to optimal level for evap.
The charcoal canister is designed to hold gasoline vapor.....NOT liquid fuel. By overfilling the fuel tank the charcoal canister is flooded with fuel and very little liquid fuel in the canister will vaporize when the ECM runs a purge cycle. There is no flow through the canister, it's only exposed to pressure and vacuum differentials when operating. Pressure puts vapors into the canister for short term storage, and vacuum evacuates the vapors when a purge is commanded by the ECM. Never, ever "top off your tank!" This could happen to you! A very expensive lesson!
@@ajwilson605 That may be true but I don't see it as much of an issue as it seems here. If it were, mfrs would put in check valves to prevent or at least resist liquids from entering. The reason usually given to consumers to not top off is to prevent spillage. But lets review what we see in the video. The EVAP canister is disconnected from the tank and the hose to the canister disconnected from the tank is pinched off. No liquid fuel leaking out. The tube clamp is removed, and smoke comes out, not liquid fuel. But when the gas cap is removed after all hoses connected and valve commanded open, fuel comes out of the filler tube but only after applying vapor pressure into the tank through the evap system. So it is the filler tube that has liquid fuel in it at this time and is being pushed out and not from anywhere else. Under normal operation, the tank would have pressure equal to ambient air or a vacuum, never pressure exceeding the ambient air pressure. So it is important during the test that the tank be anywhere from 1/2 to 3/4 full, not more, which was specified by the scan tool. More than that and you may get a mis-diagnosis.
Gees, I hope you got to charge him for the diagnosis. Being in the consultant business myself, all you can do is tell the client what the issue is and what the ramifications will be. What they decide to do with that information is their decision.
Absolutely 100% there better have been a diagnostic charge…a person has a problem they can’t figure out and take it to experts/professionals who deal with those problems….if they spend their time and money on equipment to do their job that you asked them to do then they absolutely deserve to be compensated for it Ray if I find out you don’t get paid for diagnosing issues when a customer declines work….I’m going be real sad and very disappointed in the company you work for…there should always be a policy in place by them for these situations
Ray , listening to your friend description yesterday, was an eye opener. Your drive and determination to make a good life for you and your family is outstanding. Overcoming the many obstacles in your way has provided me with more of an appreciation of you. Your pleasant outlook on life, your mechanical knowledge,/ablities, and strong work ethic, is exceptional. The world needs more Rays. If you get a chance, watch the video about Ray made by his friend. The video is very well done.
I use to fill to top of tank . Never knew you could destroy a part doing that haven't done it in 35 yrs . And thanks to you will never do it again.never going over full . Again . Thanks for the heads-up 👍
Back in the day, before all the smog stuff, we used to start the engine and then use an unlit propane torch to run the nozzle over all the possible places a vacuum leak could happen. If there was one, the engine would rev up a bit as the vacuum sucked in the propane gas. Worked flawlessly every time we used it.
Yeah, it's challenging to ignore the initial gut feeling when troubleshooting but following a sound methodology for analysis is far more efficient over time. Oh, you already checked that? Let me test it. But it's not the problem. Yeah, I'm just gonna test it. Lol
A sign of the times. Nobody wants to accept responsibility for their own actions, even when presented with the evidence. It's much easier to blame somebody else.
This is how people have always behaved. The only thing that's new is the Internet, which filters out all the good and only ever shows you the worst of humanity
The beauty part of the whole situation is the following: You can't be bothered by someone's insult if you don't care what they think. By dismissing your diagnosis, this customer has made it clear that his opinion isn't worth your time or your worry.
So hard to try to help people out like this who don’t want to believe their actions were what caused the issue in the first place… your work speaks for itself and even though I just watch your videos as a young mechanic the way you go about diagnostics truly helps me figure out where to start and what to check. I’ve learned a lot over the years from guys like you who are genuine and honest mechanics.
I did Tech Support call centers for 25+ years. When I started late 90's people were nice then about when Obummer came into office they all turned into Karen's yelling and screaming that they didn't do it. It wasn't their fault even when you proved that it was their fail. Our society is falling fast as it has just gotten worse and worse since then in call centers. My last one was cable company and it was people screaming and yelling it wasn't their fault that they didn't pay the bill. Even when they admitted that they didn't pay the bill.
Human nature sheesh. In all my years I’ve only argued with a mechanic once. A small shop they evacuated my AC. They were supposed to charge it but they said it leaked. I paid. Took it to the dealer who tested it no leak, they charged the system it worked perfectly. Took the guy to the Bureau of automotive repair. Got my money back from the first guy. Cost me 100 bucks at the dealer. Otherwise I’ve had reputable mechanics. Kudos to you Ray you’re a cut above.
I had it where we needed to replace one of the front fenders from a dear ramming it. They told us it would take about 2 weeks to get the parts, 3 months later we still didn't have the car. They gave it back clearly with 10,000 extra miles and the entire inside was cleaned out, they clearly took our car while we were gone. Then only about a week after getting our car back, we were robbed specifically targetting gear we had in the car. It can't be a coincidence. It was a GM Dealer that did the repairs.
I don't know the intricacies of how my car works, but there's something incredibly satisfying about watching a diagnostic work-through even though I don't know what's going on. I also learned something today. 20 minutes well spent
Same, people who still do Watch repair are pretty cool to follow along with too, the "Wrist Watch Revival" channel especially since he talks you threw his whole process
Nice thorough diagnostic work Ray. It’s always sad to hear that a customer isn’t willing to hear out the diag and do the repair as well as hear how to prevent it in the future. Hope they get it taken care of and stop overfilling their tank!
People need education when the pump clicks you are full stop cramming more gas in you are just going to screw up the evap system. It’s there to release pressure from the tank as you fill up the gas fumes are collected in the canister then reburned in the engine kinda like extra gas there. When you over fill now the gas tank has no room for expansion and the canister gets filled with gas and it screws everything up. When it clicks your done any amount not charged at the pump will get rebated back into your account so stop worrying about trying to reach that extra dollar at the pump.
@@ryans413 Way back in the day, before evap systems, when gasoline had lead added, "topping off" did no harm besides spilling that lovely toxic mixture on the ground. Some older people still think that topping off is a harmless procedure, and we get what he have here today.
You are correct. Never top off the fuel tank!! When you do there is a good possibility you will flood that charcoal filter with fuel and the canister will no longer work. If this happens in dusty conditions it will turn into cement inside that filter. Been there seen that. I enjoy your videos. Keep up the good work.
I did the same thing to my Chevy Colorado once. I didn't know any better. I was commuting 180 miles round trip 6 days a week. I would try to squeeze in as much fuel as I could so I wouldn't have to stop for gas that extra time every week. I went through 3 canisters before anyone clued me in. I felt so dumb when the mechanic explained it. I was really nice about it, though, and thanked him. So, I get where the guy is coming from but at the same time, you gotta take the education with humility. He was probably embarrassed and his natural reaction was to lash out. Good luck to em.
I have worked on vehicles for over 45 years and I've never heard about this. It makes sense though. I guess everything I've worked on, including my own, is owned by poor people who have never filled up their tanks but maybe once a year at most
I am so fascinated at how knowledgeable you are. I used to be a diesel mechanic back in the day. Dealing with those types of customers was so frustrating. Just watching your videos makes my day. Thanks for the great content!
Great video !! I'm one of those guys that always squeezed in another dollar or 2 of gas after the pump clicks off....but I won't anymore after seeing this video. Thanks Rainman 👍👍
The minute I saw they had a brand new canister and vent valve I had my suspicions. I’ve run into this a couple of times. Typically I’ve found that the over flow/vent line to the tank has been particularly or completely clogged so the gasoline backs up into the canister before it should, while filling up.
You did a great job diagnosing the vehicle. Mechanics, dealerships, and owner's manuals state do not overfill gas tank or words to that effect. Great job.
I must say that on occasion, I am guilty of overfilling my gas tank like this. I have never experienced any issues arise from doing so but I now understand why it would be a good idea to never do it again. Thank you once again sir for your videos. And I hope the guy who owns this toyota eventually realizes you were right and maybe even comes back to apologize to you.
Does it depend on the manufacturer? I always brim my car and drive it until just vapour. A mate of mine said this is bad because one could get grit at full - which could block injectors. I get that running out of fuel is also bad. Mine is VW 1.2 TSi. But if used to do it on Vauxhall (GM engine) 1.4 and 1.6. will be YouTubing to find out what the risks are.
@@stephenhookings1985 without looking up the specifics of any evap system that your engine may or may not have I'm just going to say yes, it is bad. That charcoal canister gets filled up with gasoline and ruins it I would say roughly 90% of the charcoal canisters that we replace are caused by customer filling to the brim and then going further.
Over filling it puts your charcoal canister at risk. If it sucks up liquid gasoline, it's finished! Running it down to the fumes puts your fuel pump at risk, but it's not because of grit in the tank. That's a very old misunderstanding. The fuel pump is designed to be fully submerged in fuel to cool itself down. When you run the tank very low on fuel, the fuel pump gets too hot and starts slowly taking internal damage. If it happens enough times, the fuel pump burns out and stops running. Generally speaking it's good to never go below 1/4 tank if you can help it.
I seem to recall the warnings in the owner’s manuals on my (old) Toyotas and “new” Ford to NOT top off the fuel tank, with an explanation that exactly this result could happen. The gas pumps also warn “Do not top off fuel” on all the stations. Customer could have read that but did not or refused to accept it.
Can't tell you how many times I've filled my gas tank all the way up. Especially on long trips. Very glad I watched this video. You rock Ray! (Rocking Ray) ?
Its moronic to try to chase fuel prices to that level. Over time you are going to overfill at an expensive price just as often as at a cheap one. My dad ran a mechanic shop back in the day (probably before the purge system was invented) and he always told me not to top up unless I knew I was driving some distance before shutting down. Especially on hot days. Gas in underground tanks is colder than the cars tank, so a chock full tank will expand and vent fuel. So I just don't overfill. No gain, possible pain=don't do it.
I love videos that involve troubleshooting via electronics. It reminds me of trying to troubleshoot a motherboard in a computer to find a dead capacitor or broken trace.
You can't check a solenoid on sound alone. It's like a relay and you have to verify the valve or contact is functioning by checking the in/out. It seems to me like you have stumbled onto a lottery ticket if you can engineer a EVAP tester. I have a multimeter. I have a scope. I have a Timing light. I have noid lights. I have spark testers. I have battery testers. All I can see is you need a gas can to remove gas and PROPERLY test the system. In this case I would advise to keep maximum gas tank 1/2 to 3/4 for eternity, offer a free confirmation in 2 weeks! My friend had the same issue parking on a steep hill... it floods the system.
I have to admit, this is the first time I've heard that over filling the fuel tank can flood the charcoal canister and ruin it. Sure, I have seen the instructions to not over fill, but assumed that was just to prevent spills. And I am not in the habit of "topping up" the tank anyway... So have probably never made that mistake. But, hey, it's good to know and proves you can teach an old dog like me something new every now and then!
Common issue on Toyotas... never ever go past that first click! The worst is when a malfunction in the nozzle does it, it happened to me in fact! The tube in the top goes directly into the canister, and floods it... one of the rare stupid designs in Toyotas. Now this can happen on other cars, but Toyotas are REALLY touchy on an overfilled tank, makes me cringe when I see people topping off at the pumps. At the Dealer it's a $2K job.
Ask yourself this why do you think the pump clicks off it’s not just cause it randomly stoped it did that cause your tanks full by continuing to pump more gas in you are now putting too much in for the system to work properly no cars gas tank gets filled 100% there’s always a small section of space for expansion as you fill up the gas vapours are collected by the charcoal canister and are held until the computer commands the fumes to be reburned in the engine kinda like extra gas there. If you over fill there no no room for expansion in the gas tank and and the canister gets filled with gas so no gas fumes are being burned and the tank could start to buckle under the pressure. If you ever remove the gas cap and hear pressure being released that’s probably a result of a bad canister from overfilling. I always say when it clicks your done
@@ryans413 Unless the nozzle doesn't shut off, and fuel starts pouring out which does happen now and then (especially here in California with our vapor recovery nozzles)... and trust me 100% chance the can is full in that situation, especially on the 'yotas as there is a fairly large tube in the filler area that goes directly to the pump on the canister... if you are lucky just the pump gets flooded (if it's caught quickly) which is why you can find the OEM Denzo pumps on Amazon as it's a common issue on Toyotas from the late 90's.
@@pinkertonfld Yes if gas starts coming out of the filler neck yep it’s way overfilled and the gas pump not working correctly once the vapours hit the nozzle it should click off how they work
@@ryans413 Ummm, some cars I have owned the trigger clicked continuously because of something causing the trigger to switch off, not because tank is full. I would have thought it was purely a safety feature, not down to protecting the vehicle.
So frustrating to see the obvious diagnosis but semi understandable in a way that the customer doesn't understand but that's why the fuel pump clicks off so that you do not overfill as it leaks down into the vapor lines
@@marksmallman4572 yes in the video we weren't talking about diesel not everybody drives a diesel I believe the majority of people that would overfill are diesel drivers like myself there is a return vent line to the tank to prevent that spillage from aggressively pumping out of the spout doesn't work all the time but there is one. 👍🤣
Nice that you stuck to it even when ideas seemed exhausted. Congrats on finding it! Didn’t know that overfilling can lead to all those issues. Maybe guy will cool off and realize… what no one wants to hear, “what you are doing sir, is wrong”
Ray, you’re absolutely correct. I , over a number of years, topped off my tank till I ran on the ground While traveling. Never listened to people tell me I shouldn’t. Never gave me an explanation as to why but that I shouldn’t. Week years later I found out why after changing the canister, valves and tank (good old Pennsylvania rust at the fuel pump orifice) I became a believer. Yes it is a Toyota Tacoma. Also, never used Dorman parts. Always original or from the manufacturer who makes the original. Your customer is just being stubborn and probably one of those e persons you can always tell but not tell them much. Have a great day. Good diagnosis.
Well you yourself weren't a "believer" until it happened to you. I expect this guy is the same, but there is no "broken" part he can be shown. He has probably done this for a long time, so it sounds like a scam to him. I expect he will come around when he does his own research. Pity he reacted the way he did. I disagree with people quite often, but I keep quiet and inform myself before saying anything, since I am fully aware I don't know everything there is to know.
I made the mistake of overfilling gas tank on Honda Odyssey. My mechanic told me, "Don't do that!". So I quit. Problem solved, after I paid him to fix it. I realize most of you mechanics are looking out for us little guys, and I appreciate it. I'm a plumber, so I get a lot of the customer know it all headaches you guys do, and it ain't no fun, but the good customers make it all worthwhile.
No professional expertise on this repair, but I've been a DIY mechanic since the late 60's and your workflow and diagnostic steps seem very well thought out. I'm impressed as always.
Great work Ray. Australia doesn’t have the stringent pollution rules you guys have but trickle filling the tank to max creates problems I never considered. Love your work and the vids. I’m learning heaps watching how you tackle your work. 🇦🇺👍
I never knew over filling a tank could cause any problem apart from spilling out. ( never owned petrol power later than 1991) Intimidating looking set up they have now. Outstanding diagnosis work. Thanks for the schooling. As for the customer.... too much pride, guess they will figure it out after paying a few times over to be told the same thing. Thanks for the upload. Most appreciated.
I am a mechanic and yes overfilling your gas tank can damage the charcoal canister (a device that catches fuel vapors). I suspect we will be seeing more and more of these problems because of rising gas prices (people trying to fill their cars to the absolute maximum because they fear that it's going to be more expensive the next time they fill up).
A friend of mine had the over filling issue I found out when I replaced a second charcoal canister I less than a year. He would click click & click again when filling the tank the second bad canister was full of raw liquid fuel, I explained why they call it a"vapor" canister. Good point.
Thanks for explaining WHY you dont top off the tank. I had heard that but am guilty of doing that in the past. Now I know why thats a bad idea so you might just have saved me some serious dough. One click and done at the pump from now on. I've learned alot watching a truly great mechanic (YOU) Thanks.
I’m a licensed mechanic with a smoke machine this is very good diagnostic for every boneheaded customer honesty will give you lots of good lifetime customers.Look after the good customers who trust you and get rid of the ones who don’t
I can understand the guys feelings hes probably been told it's all the stuff he got repaired and what they told him to give him the confidence that it couldn't have been his fault. I wish you were in Australia as you are the most professional knowledgeable honest mechanic. If these customers watched your videos they would have complete trust in your work
Oh my!! Not being up front with you in the beginning turned out to be a clue to the end. I believe this "Customer" owes you and the shop an apology. You have a great attitude. Great effort on your part Rainman!
Well I'm not sure not saying he overfills is being dishonest. He probably didn't know that was bad for the car. Problem with mentioning everything to a mechanic is that it can bias the diagnostic process.
@@Cheepchipsable I didn't mention anything about the overfill or dishonesty. Being up front with the recent vehicle history is more of a benefit to the customer. Having to contact the customer twice for bits of vehicle history at a time is not beneficial to anyone. Then being accused of up selling. It's to bad the customer has probably been treated bad some where else. Rainman busted his butt diagnosing the problem. Whats wrong with a gracious "Thank You"? My goal is to always be a great customer. Have a great day! 👍
Thank you for this video Ray. After years of telling my wife that she shouldn't fill the tank past the first click, I now have video proof that I was right!
I'm impressed how well you took it. I probably would have been a lot more upset at the customer. But you are right, sometimes people just need time to digest things and accept their own responsibility, it is human. Either way, kudos to you for your great attitude.
When someone doesn't know what is wrong with their car, takes it to an experienced expert, then doesn't want to listen to the well performed comprehensive diagnosis of the issue because it was user error.... 😖😖😖
You might want to send a letter to his mailing address in the hopes his family reads what's going on. Grandpa escaped in the Camry again and he's been trying to fix that same gas vent since 2011. He makes sure to let everyone know each year on the Christmas cards he sends out to overfill their gas tanks. "If it doesn't click 8 times, Grandpa isn't proud of you." Ray you've disrupted a long family tradition.
Love the way you dug in and tested each component of the system. I know sooo many people that couldn’t do that, that call themselves good mechanics. I wonder what the evap readiness monitor said?
Just a tip, you may hear the solenoids clicking and reponding electrically but they still may be leaking internally. had a 2014 ford escape and the purge valve would click when activated through the scan tool, however after removing the purge valve, smoke would flow through either way without impedence when the purge valve is supposed to be normally closed until electrically activated
wow, i think i'm one of the "perfect customer" you could have: I deliver my car washed outside, no mess inside and i listen to whatever feil was detect and whatever best course of action to repair. As i know that i do not know nothing about mechanics and autos, i tend to follow the expert on the matter. No absolute problem to take my responsability for my own ignorance, so i would love to have a personal mechanic like you! i would absolutely pay your fee and more with a smile, knowing you did your best to service my car!
I agree to sending the car clean inside and out to be serviced. I also keep the engine bay very clean too. I think it tells the tech I care about my vehicle!
Been through all the steps you went through including swapping a known good canister. The problem with this car is likely the overflow control for the fuel tank. They go bad on this generation car and when that happens and combined with a customer that likes to top up obsessively leads to this on this generation Toyota. You can see the control valve at the top of the tank when you ask your audience if we see any smoke. I'm pretty sure I have the same issue with my GFs 1999 camry. Love the videos. Keep up the good work.
Hi Ray. I haven't been watching long time, but I want to thank you for giving me the confidence to try to work on things I normally wouldn't try. I have never been good with mechanical things, but since watching your videos I have more confidence to try! My home AC started making noise, and I used your technique and what I learn from watching you to try to diagnose and work on it. I was able to pull out the control board and blower assembly thing and know what the problem is now! Thank you again for being so inspiration!
I'm not a mechanic, but love seeing you diagnose. I have learned that the key to diagnostics, is to have a plan of action and to follow that plan. Methodical. The average layman car owner would throw parts at it, upon free recommendation of the Auto Parts store employee and confirmed by a shade tree mechanic buddy. Enjoyable and informative....even for the non mechanic.
I can understand both sides of this issue. I had a Camaro that I was overfilling the tank, not knowing that was a bad thing. I replaced the canister, and when I stored the car for the winter, I overfilled it thinking I was protecting it from any kind of contaminates getting into a less than full tank. Well, to my surprise when spring came around and I started driving it again, there was the gasoline odor again because I had saturated the canister. I sure wished I would have figured this out sooner, now I needed another canister, and when the gas pump stopped, I stopped filling.
Couple tips you where right to fill the tank up for winter but really half full good enough anything less will cause issue. When you fill the car up and the pump clicks off your done it’s full the system all works together with the gas pump to tell the pump when it’s full. As you fill up the gas vapours also fill up the tank so as the gas level increases in the tank since gas is heavier then the vapours the vapours sit ontop of the gas as you fill up once those vapours climb up the filler neck and hit the pump hand it tells the pump you are full and shuts off stop filling at that point your done. If you over fill now there no room in the gas tank and those vapours gets saturated in gas filling the canister now and that can cause the gas tank to buckle under pressure. Another tip when your gas gauge reads a quarter of a tank left look at that as empty and go fill up the gas helps cool the fuel pump if you constantly let the tank run so low the gas light comes on it can run the pump hot shorting it life span.
So many people have been ripped off by crooked and lousy mechanics I can understand the customers mind set. BUT you are doing everything right! In the end it's the customers loss!
I really like your videos. Just came across them. I'm an auto body repair mechanic trying to start my own channel and run across all these issues. Please keep posting it helps our community of repair monkeys with your experience and techniques!!! Earned a solid subscriber
Great video! Very impressed by your diagnostic prowess. Way above my back yard mechanic pay grade. I also didn't know you can damage the evap system by overfilling the gas tank. Good to know as I am (was) guilty of doing that myself.
On a management course I attended with a group of others, a psychologist asked us to write down the two best moments of our lives, and the two worst. We were then asked to remark on who was responsible for the 'best' moments. and who responsible for the 'worst'. Close to the end of the class, the summary we were presented with, is that "we" always claim responsibility for the best moments (like personal achievements), and the worst, always down to "someone else", even if we'd set up the situation prior to the disaster arriving. The conclusion then, is that bad things that happen to us, HAVE TO assigned to someone else. This is a great example of proof that condition exists. I've been working on and fixing computers for over 30 years. (386 + DOS days.) 6 months ago I got asked to sort out a fellas problem with a printer. He thought it would be a simple 2 minute job, which it wasn't, not least because of his peculiar setup. Anyhow, I got the same reaction experienced here. A fella who knows next to nothing about modern operating systems, telling me I was doing something wrong. Even if I had been, how was he to know? I was doing this as a favour, so the 15 minutes I spent on resolving the matter didn't cost him anything, but his pissy attitude will mean he won't be getting free help in the future. Seems I fixed the problem (I was told later), but I didn't get thanked for it either. Honestly, some people should come with 'health' warnings.
Everyone thinks it will be a 2 minute fix. I've met so many people who admit they know nothing about a subject, then proceed to argue with you when you try and explain something.
My computer sales/repair/throw-in-the-trash experiences began in 1981 prior to the first IBM PC and PC compatibles. I could tell a ton (and the stories don't weigh much - at all!) of such stories. It's amazing when people build/assemble their own computers from ordered parts, can't get it to power up, and then proceed to try to tell you what's wrong when start to fix the problem. I'm somewhat to mostly retired now and can look back and laugh. Out loud!
this is interesting because some of the worst moments of my life, I blame myself for, where as some of the best I can think of, I definitely give credit to other people for. Is there something wrong with me? lol

Although the customer was close minded, take solace in the fact that you taught me to never overfill my fuel tank.
... and a lot of us others too! Won't be trying to get that extra liter in anymore.
Me too. Been driving for 35 years, and this is new info to me. It makes perfect sense, but I've never given it a second thought until now.
@@andytyler6252That is how I damaged my stock charcoal canister. Overfilled it and it died over time. Got a replacement and learned my lesson.
Some vehicles actually have a vent cut valve on the tank for that purpose. If the fuel level is too high, the valve closes from the fuel and nothing will be allowed into the EVAP system from the tank (i think only on steel tanks, but idk). Perhaps if that vehicle had such a valve, the system was being compromised by the pressure induced by the smoke machine, or perhaps the valve was faulty (again, this is assuming the tank had such a "liquid valve" in the first place).
@@GReaper Yep, Im guilty of doing it, Never knew this would happen, wont do it again after this.
I don't mind losing customers, but i do mind losing GOOD customers. No loss here.
Carey you watch these videos too. I like your channel by the way.
you are so right... sometimes you can spot them early enough but it's amazing how some of them act.
I'm a Texan girl living in Milwaukee. One good mechanic did a first good job on my 03 Lightning. 2021- he hired goons to trouble shoot electronics. Leaving a sound system cap totally powered up running computer tests. Yes he replaced my shocks (tried hard to talk me out of Bilsteins bc "they ride stiff". Over 100mph you want them. 140mph Then)! My always 12psi boost was dropped to a depressing 8 psi and less shriek. It took me 8 mo of almost redoing wire harness myself. I had to guess at some wild jerryrigging they did. My sound system is almost 3000W peak. I was planning to pull it and all fresh wires components. Cried driving it home. I disconnected sound and capacitor everything when I saw what they did. "Hot when on" relay got very hot and started melting. I really liked front office guy I can't drill thru the firewall. See that huge red wire? I drilled it! He still blew me off as stupid. The best mechanic is your self. Or my dad. I let this mechanic work on winter beater car. How do you screw up an 05 Impala? Yes, Lightnings are complex no diagrams or parts. But the Impala? Just air vent fan? Which promptly broke.
That kind of service will get you laughed out of a Texas town. Mechanic knew he had a 8-10k high budget, had it 8 weeks. He charged 2k. I said I don't want cheap I want it dead perfect. All he did right was new suspension and steering fluid leak. I am the customer you don't want to lose.

It's amazing that the customer didn't know what was wrong with the car. Hence, it showed up in your possession to diagnose the car, you diagnose the problem, and tell him the diagnosing procedure and what causing the failure and immediately he became the expert and said you were wrong. Ray one thing you can't fix is ignorance or stupidity 🙅
Ray, early on you spotted the problem by looking at the fuel gauge. But you went through the entire process to confirm the hypothesis. Great job. Maybe he's just embarrassed, and he'll learn to stop overfilling his tank.
I feel your frustration, Ray. When you pour your heart and soul into your work, you open yourself up to mindless jerks who think nothing of crushing spirits in order to further their own ends. In this case, the customer couldn't believe that he'd made a mistake. Rather than laughing it off and learning from the experience, he kicks the first dog he sees; unfortunately, that was you. I've learned so much from your videos, and you've become a vital part of my morning routine. You have the perfect combination of technical acumen, personality, and humor that guarantees success. I hope you can shrug this off and understand that there are some real dirt bags in this world that simply can't be pleased and don't deserve another moment of your time. Goosfraba, brother.

"mindless jerks who think nothing of crushing spirits in order to further their own ends." - SO TRUE. Everyone made mistakes in their life.
I think you guys missed the mark on this one. Unto most people, a mechanic's reputation is just a hair above a used car salesman. Given the abundantly poor service from many a dealership, you can't blame them. I think the guy has had some bad experiences in the past and is fearful that most mechanics are just trying to take him for a ride.
Just have to build up a rapport with the customer base to help alleviate them of these perceptions and false conclusions.
Ditto!
@@nottelling4828 most of the time, the stereotypical mechanics have a bad reputation, but Ray is like a king of car repair and an exception to the rule.
He should showcase his channel at the shop as proof of his professionalism and dedication to doing things properly.
It's very easy to diagnose a simple problem when all the time consuming,preliminary work is done. Great job Rainman
Wow! That was a heck of a thorough, well-thought-out, troubleshooting chain of events ! The only thing you can't fix is stupid! Outstandingly good job!
It's unfortunate that the customer was unwilling to listen, though on the other hand you've taught all of us a valuable lesson for why we should never overfill tanks.
I overfilled my tank once and it started chain of events that ended up costing me a lot of money. I learned that lesson the hard way.
Brilliant diagnosis; so well done to you. We can please most people most of the time but cannot please all people all of the time. The customer is not always right. Thanks for sharing.
I hate the term "The customer is always right", smh, I can run with "Customer is king" but obviously the customer is not always right...
@@WhiteBuffalo59 ....stats show that the customer is rarely right.
I agree. I did tech support for years. We were taught that the customer is always right until you can prove otherwise. I personally went with, the customer experience is always unique. I knew of techs that argued with customers, telling them that what they experienced is impossible. It's not impossible, just improbable. And, customers hate hearing that the problem is caused by a user error. No one likes being told they are the problem/cause of the problem.
@@TimothyWelty "User error", we call that an I D ten T error or written another way ID10T .....lol
What's so brilliant about a simple diagnosis?
Normally these type of people are "KNOW ALLS" that never have achieved anything in life except riding on opportunities. You on the other hand have gone out of your way to lay the proof on the table. You are a thorough GENTLEMAN concerning your situation. Well done, you are the winner.
Dude, nice work. That was some serious diagnosing skill. I'm glad I sat through and saw your decision making.

Another masterclass in diagnostics, well done sir! Re: the disgruntled customer; Always remember "No good deed goes unpunished." Don't take it personally. We love ya!
I was expecting that kind of a response from the customer, having all these parts replaced previously and not saying anything about it, he just needed a confirmed repair as a second opinion, made all the fuss just to not pay for your work and diagnosis, and he got what he wanted and got away with it, great work Ray, as usual.
People are fucking DISGusTING truly.
I would hope that the customer would have been charged a diagnosis fee for this work.
Hey I was wondering that are you saying after all that work he’s not going to get paid for the service he did so far
@@garthmuir6023 that's right, all that diagnostic work was free for the customer, and Ray probably didn't make a cent either.

Since this OG was a teen I have had many jobs that required interacting w the public. From being a stock boy at a neighbor's pharmacy to my last 26 years as a Psychiatric RN. I learned many lessons in my working years. When one develops expertise in a particular area allowing that expertise to, "speak for itself", is often the 1st line of defense in dealing w difficult, unreasonable & those who go so far as to question a person's motive.

@@mistie710 I was going for the " low hanging fruit".
My dad had a motto that he always followed. Sometimes, you have to fire a customer. Should not happen often, but every once in a while, you get one that just isn't worth keeping.
The uncut zip ties are for trimming weeds on the side of the road!
Note to self: overfilling the gas tank is worse than I thought! It's great to learn new things from you Ray. Once again, a thorough and fantastic diag that will be useful to me someday.
you see in my car being that it is a 2013 fiesta, it has the ford "easy fuel" neck which is a capless neck, I find it quite hard to over fill the tank infact if the nozzle isn't in the exact right position its just generally hard to fill the tank lol
The guy obviously isn't stopping at the first click, he is prolly pulling the nozzle out, and trickling it in, until its full full.
I was thinking the exact same thing, I didn't know there was a charcoal filter in the gas tank assembly to help with the fumes and that over filling would kill it. I always just though overfilling was bad because it would cause fuel to over-spill only.
@@Bamahut The tubes connected to the gas tank, are connected to the filler neck, as long as you stop at the first click, the level of petrol will be below the connections, if you goto the trouble of over filling, looks like you can fill the level over the height of the connections, then you fill the cannister up with fuel.
Only time I've ever overfilled my tank was with a faulty pump that didn't stop filling and spewed diesel on me and my car.
You have waaaay more patience and professionalism than I am capable of in such a situation. Props on keeping your cool
Yeah,you're right, but I'm sure he has a lot of works to do on others customers cars , and sadly the bad mentality and the total lack of honesty is creepy nowadays
I paused at 8:30 to guess/comment before continuing:
I would detach the evap canister first to check if it's filled with gas. I sometimes see this happen when people habitually overfill their fuel tank.
And now back to our regularly scheduled video...
I've always heard that you should not over fill the gas tank, now I've seen visual proof that over filling is bad for the car. Good video!
Same here. You'd think though the evap canister would be above the tank level and a check valve to prevent liquid from getting in.
I get that evap can't do its job when tank is full, but it doesn't need to as there's no void to generate vapors to be purged.
Yup, no more "topping off" for me. Well, maybe to the next dollar, but with gas prices these days, that shouldn't put too much extra gas in the tank.
When you are filling up your tank, how are those vapors routed into the canister vs just coming back out the nozzle? I understand the vacuum of the engine sucking off the vapors from the tank etc, but still not understanding how vapors get to the canister when filling up with gas.. Sometimes when I'm filling up my truck, the gas pumps nozzle keeps cutting off repeatedly up to a point where it seems to stop and let me finish filling up.
@@captinbeyond Then it's filling too fast. It's not the vapours that get to the canister in this case. It's when the valve opens, the fuel level is too high and it sucks raw fuel in rather than vapours.
@@captinbeyond Think of a straw in a cup, straw above the liquid line, you suck air. Straw below the liquid line, you get liquid. Overfill the gas tank and now the liquid line is too high allowing liquid to flow in place of the intended vapor.
The charcoal canister is filled with many tiny charcoal pellets. The pellets absorb the gas vapor and allow fresh air to flow around them via the tank vent valve. The gas tank must vent to atmosphere except when the vehicles ECU runs the evap system test cycle. If the gas tank can’t vent it will collapse inward from the vacuum generated by the purge valve opening .
When the charcoal pellets saturate with liquid they expand and turn to mush. Then there is no airflow through the canister to vent the gas tank to atmosphere.
Don’t overfill your gas tank.
As my dear departed father used to say, "There is an ASS for every seat"!!! This profound statement is the result of our family owning an autobody repair shop for 64 years and dealing with a wide range of Humanoids that would wonder into our shop.

"There are more assholes in the world than asses."
For sure. Wish I had a nickel for everyone who said "As long as you have the paint in the gun"
Haha, well said....and I totally agree with your dad
No good deed goes unpunished, perfect saying
For sure I tried to round out my fuel cost to an even number. Click, click and another click. While this customer did not appreciate it your viewers did. I for one learned a valuable lesson and no longer try to overfill
The hardest part of being a mechanic/technician is the customers. Lol
It’s mostly cause the costumer is not educated and thinks they know what the problem is and can’t take another response. These people just waste everyone’s times the customers and the mechanics. Put your pride to side and be open to a mechanics expertise. But for these customers it’s hard cause they believe they did nothing wrong and have been too multiple shops and think they are being screwed but in fact it’s the customer really that’s causing the issue. It can be frustrating as a mechanic

Click bait "you're fired"? Your videos are awesome, no need for hyped titles to get us to watch, im subscribed and I still think you're a mechanical genius!🍺👍
I remember learning about the EVAP system in school but did not fully understand the system, but this is a perfect example of diagnostic to the system. Thank you!!!
Excellent work on the diagnosis. I've had customers throw full on temper tantrums when they find out the issue was caused by them. Nothing to do here except tell the customer you can't help them. Unfortunately, the customer will tell 1000 people how you tried to "rip them off". On the flip side, if you found something like the vent solenoid not plugged in, connected it, told them "no charge, have a great day", they'd never tell a soul. 😐
so true!!
As a man who's been in the service business ( musical instruments) since 1976, I concur. It's the " no good deed goes unpunished" thing. When I've found an honest helpful carpenter, plumber, lawyer, mechanic, roofer, (you name it) I just never go anywhwere else. I think it's important to support the good folks who support you. ! Promotes that rewarding sense of comminity, where we all become friends. Friends are good to have. This man seems like a good guy who was really trying hard to help out.
Depends on individual, but appreciate the all or none thinking.
The customer may not have appreciated your hard work but we sure do. I’ve done an extra top up with the fuel myself but now seeing what it can do, I will never do it again. You have helped to reduce a needless repair, thanks Ray! =]
yeah i a too overfilling my Volvo v70 2003 i do not know if the car have a Evap system but i will not overfill from now on :)
extra top up is ok up to a point. What i do is once the fuel clicks and stops, i add a bit more just so that the dollar amount is exact. There is a time where i overfilled to get the dollar amount but the fuel would shoot out a bit. However my car over estimates the fuel and the low fuel warning light doesn't come on and since its an old car its not quite an issue and i dont run into this issue either.
Me too.
I overfill my diesel car all the time. It doesn't have a vapor recovery system so I have no fear of this problem.
People doesn't understanding over filling fuel is not a problem. LOL!!!
Thank you for adding the text slides. I think its a great addition.
Let's not forget that the tank is full. The scan tool did say tank should be 1/2 to 3/4 full for diagnostics.
For all we know, evap may still work once fuel gets down to optimal level for evap.
The charcoal canister is designed to hold gasoline vapor.....NOT liquid fuel. By overfilling the fuel tank the charcoal canister is flooded with fuel and very little liquid fuel in the canister will vaporize when the ECM runs a purge cycle. There is no flow through the canister, it's only exposed to pressure and vacuum differentials when operating. Pressure puts vapors into the canister for short term storage, and vacuum evacuates the vapors when a purge is commanded by the ECM. Never, ever "top off your tank!" This could happen to you! A very expensive lesson!
@@ajwilson605 That may be true but I don't see it as much of an issue as it seems here.
If it were, mfrs would put in check valves to prevent or at least resist liquids from entering. The reason usually given to consumers to not top off is to prevent spillage.
But lets review what we see in the video.
The EVAP canister is disconnected from the tank and the hose to the canister disconnected from the tank is pinched off.
No liquid fuel leaking out.
The tube clamp is removed, and smoke comes out, not liquid fuel.
But when the gas cap is removed after all hoses connected and valve commanded open, fuel comes out of the filler tube but only after applying vapor pressure into the tank through the evap system.
So it is the filler tube that has liquid fuel in it at this time and is being pushed out and not from anywhere else.
Under normal operation, the tank would have pressure equal to ambient air or a vacuum, never pressure exceeding the ambient air pressure.
So it is important during the test that the tank be anywhere from 1/2 to 3/4 full, not more, which was specified by the scan tool. More than that and you may get a mis-diagnosis.
Gees, I hope you got to charge him for the diagnosis. Being in the consultant business myself, all you can do is tell the client what the issue is and what the ramifications will be. What they decide to do with that information is their decision.
Absolutely 100% there better have been a diagnostic charge…a person has a problem they can’t figure out and take it to experts/professionals who deal with those problems….if they spend their time and money on equipment to do their job that you asked them to do then they absolutely deserve to be compensated for it
Ray if I find out you don’t get paid for diagnosing issues when a customer declines work….I’m going be real sad and very disappointed in the company you work for…there should always be a policy in place by them for these situations
A lot of extra work was done to get to the root of the issue.
May, just maybe, the canister will dry out and he'll stop over filling the tank.
They should pay up front for a diag.

Back in the day, before all the smog stuff, we used to start the engine and then use an unlit propane torch to run the nozzle over all the possible places a vacuum leak could happen.

This is how people have always behaved. The only thing that's new is the Internet, which filters out all the good and only ever shows you the worst of humanity
This is there should be an intelligence test before being allowed to earn a driver's license. Great diagnostics, as always.
Or.... vote
You fail to understand how dumb the majority is...
Hmmmm… I think this is attributable to the human condition. Not so much an intelligence thing.
I now have a Camry. Toyota is new to me too. Good advice you've me Ray.
The beauty part of the whole situation is the following: You can't be bothered by someone's insult if you don't care what they think. By dismissing your diagnosis, this customer has made it clear that his opinion isn't worth your time or your worry.
Could be a plot to test your skills? You passed , good job !
So hard to try to help people out like this who don’t want to believe their actions were what caused the issue in the first place… your work speaks for itself and even though I just watch your videos as a young mechanic the way you go about diagnostics truly helps me figure out where to start and what to check. I’ve learned a lot over the years from guys like you who are genuine and honest mechanics.
I did Tech Support call centers for 25+ years. When I started late 90's people were nice then about when Obummer came into office they all turned into Karen's yelling and screaming that they didn't do it. It wasn't their fault even when you proved that it was their fail. Our society is falling fast as it has just gotten worse and worse since then in call centers. My last one was cable company and it was people screaming and yelling it wasn't their fault that they didn't pay the bill. Even when they admitted that they didn't pay the bill.
Human nature sheesh. In all my years I’ve only argued with a mechanic once. A small shop they evacuated my AC. They were supposed to charge it but they said it leaked. I paid. Took it to the dealer who tested it no leak, they charged the system it worked perfectly. Took the guy to the Bureau of automotive repair. Got my money back from the first guy. Cost me 100 bucks at the dealer. Otherwise I’ve had reputable mechanics. Kudos to you Ray you’re a cut above.
I had it where we needed to replace one of the front fenders from a dear ramming it. They told us it would take about 2 weeks to get the parts, 3 months later we still didn't have the car. They gave it back clearly with 10,000 extra miles and the entire inside was cleaned out, they clearly took our car while we were gone. Then only about a week after getting our car back, we were robbed specifically targetting gear we had in the car. It can't be a coincidence. It was a GM Dealer that did the repairs.
@@Skylancer727 I doubt it was a coincidence. There was a well known audio shop near me that used to steal back what they sold...
@@Skylancer727 You actually let them do all this and did not involve Law Enforcement??? You need help...
you just taught me a lesson on over filling,never even knew it was a problem ,thanks .
I don't know the intricacies of how my car works, but there's something incredibly satisfying about watching a diagnostic work-through even though I don't know what's going on. I also learned something today. 20 minutes well spent
Same, people who still do Watch repair are pretty cool to follow along with too, the "Wrist Watch Revival" channel especially since he talks you threw his whole process
Thanks to you Ray, I never knew you could hurt something over filling the tank! THANK YOU I'M GUILTY OF DOING THAT! AGAIN THANKS!
Nice thorough diagnostic work Ray. It’s always sad to hear that a customer isn’t willing to hear out the diag and do the repair as well as hear how to prevent it in the future. Hope they get it taken care of and stop overfilling their tank!
It sounds like they just want to spend money rather than a fix to an issue they're causing.
People need education when the pump clicks you are full stop cramming more gas in you are just going to screw up the evap system. It’s there to release pressure from the tank as you fill up the gas fumes are collected in the canister then reburned in the engine kinda like extra gas there. When you over fill now the gas tank has no room for expansion and the canister gets filled with gas and it screws everything up. When it clicks your done any amount not charged at the pump will get rebated back into your account so stop worrying about trying to reach that extra dollar at the pump.
@@ryans413 Way back in the day, before evap systems, when gasoline had lead added, "topping off" did no harm besides spilling that lovely toxic mixture on the ground.
Some older people still think that topping off is a harmless procedure, and we get what he have here today.
@@MonkeyJedi99 that’s true but that’s why I said people need to educate themselves on today’s vehicles
@@ryans413 I agree completely.
You are correct. Never top off the fuel tank!! When you do there is a good possibility you will flood that charcoal filter with fuel and the canister will no longer work. If this happens in dusty conditions it will turn into cement inside that filter. Been there seen that. I enjoy your videos. Keep up the good work.
I did the same thing to my Chevy Colorado once. I didn't know any better. I was commuting 180 miles round trip 6 days a week. I would try to squeeze in as much fuel as I could so I wouldn't have to stop for gas that extra time every week. I went through 3 canisters before anyone clued me in. I felt so dumb when the mechanic explained it. I was really nice about it, though, and thanked him. So, I get where the guy is coming from but at the same time, you gotta take the education with humility. He was probably embarrassed and his natural reaction was to lash out. Good luck to em.
Great that you were willing to learn! None of us know everything and listening with an open mind is key to doing better (in almost everything)
I have worked on vehicles for over 45 years and I've never heard about this. It makes sense though. I guess everything I've worked on, including my own, is owned by poor people who have never filled up their tanks but maybe once a year at most
I am so fascinated at how knowledgeable you are. I used to be a diesel mechanic back in the day. Dealing with those types of customers was so frustrating. Just watching your videos makes my day. Thanks for the great content!
I would have tested power and ground at the CCV connector with an incandescent bulb
Great video !! I'm one of those guys that always squeezed in another dollar or 2 of gas after the pump clicks off....but I won't anymore after seeing this video. Thanks Rainman 👍👍
The minute I saw they had a brand new canister and vent valve I had my suspicions. I’ve run into this a couple of times. Typically I’ve found that the over flow/vent line to the tank has been particularly or completely clogged so the gasoline backs up into the canister before it should, while filling up.
You did a great job diagnosing the vehicle. Mechanics, dealerships, and owner's manuals state do not overfill gas tank or words to that effect. Great job.
I must say that on occasion, I am guilty of overfilling my gas tank like this. I have never experienced any issues arise from doing so but I now understand why it would be a good idea to never do it again. Thank you once again sir for your videos. And I hope the guy who owns this toyota eventually realizes you were right and maybe even comes back to apologize to you.
Does it depend on the manufacturer? I always brim my car and drive it until just vapour. A mate of mine said this is bad because one could get grit at full - which could block injectors. I get that running out of fuel is also bad.
Mine is VW 1.2 TSi. But if used to do it on Vauxhall (GM engine) 1.4 and 1.6. will be YouTubing to find out what the risks are.
@@stephenhookings1985 without looking up the specifics of any evap system that your engine may or may not have I'm just going to say yes, it is bad. That charcoal canister gets filled up with gasoline and ruins it I would say roughly 90% of the charcoal canisters that we replace are caused by customer filling to the brim and then going further.
@@stephenhookings1985 not a problem until it is. VW has a valve which can die
I used to, until I had to replace my charcoal cans and EVAP ... that killed it for me. Now I go until the pump handle clicks off and call it good
Over filling it puts your charcoal canister at risk. If it sucks up liquid gasoline, it's finished!
Running it down to the fumes puts your fuel pump at risk, but it's not because of grit in the tank. That's a very old misunderstanding. The fuel pump is designed to be fully submerged in fuel to cool itself down. When you run the tank very low on fuel, the fuel pump gets too hot and starts slowly taking internal damage. If it happens enough times, the fuel pump burns out and stops running. Generally speaking it's good to never go below 1/4 tank if you can help it.
I seem to recall the warnings in the owner’s manuals on my (old) Toyotas and “new” Ford to NOT top off the fuel tank, with an explanation that exactly this result could happen. The gas pumps also warn “Do not top off fuel” on all the stations. Customer could have read that but did not or refused to accept it.
Well, how many people actually RTFM? LOL Not many.
Can't tell you how many times I've filled my gas tank all the way up. Especially on long trips. Very glad I watched this video. You rock Ray! (Rocking Ray) ?
With gas prices going so hi lately this will happen more often. All to save a few cents! When the pump clicks off, STOP FILLING!!! Nice job Ray!
Its moronic to try to chase fuel prices to that level. Over time you are going to overfill at an expensive price just as often as at a cheap one. My dad ran a mechanic shop back in the day (probably before the purge system was invented) and he always told me not to top up unless I knew I was driving some distance before shutting down. Especially on hot days. Gas in underground tanks is colder than the cars tank, so a chock full tank will expand and vent fuel. So I just don't overfill. No gain, possible pain=don't do it.
I love videos that involve troubleshooting via electronics. It reminds me of trying to troubleshoot a motherboard in a computer to find a dead capacitor or broken trace.
I do both. I think like that sometimes
You can't check a solenoid on sound alone. It's like a relay and you have to verify the valve or contact is functioning by checking the in/out. It seems to me like you have stumbled onto a lottery ticket if you can engineer a EVAP tester. I have a multimeter. I have a scope. I have a Timing light. I have noid lights. I have spark testers. I have battery testers. All I can see is you need a gas can to remove gas and PROPERLY test the system. In this case I would advise to keep maximum gas tank 1/2 to 3/4 for eternity, offer a free confirmation in 2 weeks! My friend had the same issue parking on a steep hill... it floods the system.
I have to admit, this is the first time I've heard that over filling the fuel tank can flood the charcoal canister and ruin it. Sure, I have seen the instructions to not over fill, but assumed that was just to prevent spills. And I am not in the habit of "topping up" the tank anyway... So have probably never made that mistake.
But, hey, it's good to know and proves you can teach an old dog like me something new every now and then!
Common issue on Toyotas... never ever go past that first click! The worst is when a malfunction in the nozzle does it, it happened to me in fact! The tube in the top goes directly into the canister, and floods it... one of the rare stupid designs in Toyotas. Now this can happen on other cars, but Toyotas are REALLY touchy on an overfilled tank, makes me cringe when I see people topping off at the pumps. At the Dealer it's a $2K job.
Ask yourself this why do you think the pump clicks off it’s not just cause it randomly stoped it did that cause your tanks full by continuing to pump more gas in you are now putting too much in for the system to work properly no cars gas tank gets filled 100% there’s always a small section of space for expansion as you fill up the gas vapours are collected by the charcoal canister and are held until the computer commands the fumes to be reburned in the engine kinda like extra gas there. If you over fill there no no room for expansion in the gas tank and and the canister gets filled with gas so no gas fumes are being burned and the tank could start to buckle under the pressure. If you ever remove the gas cap and hear pressure being released that’s probably a result of a bad canister from overfilling. I always say when it clicks your done
@@ryans413 Unless the nozzle doesn't shut off, and fuel starts pouring out which does happen now and then (especially here in California with our vapor recovery nozzles)... and trust me 100% chance the can is full in that situation, especially on the 'yotas as there is a fairly large tube in the filler area that goes directly to the pump on the canister... if you are lucky just the pump gets flooded (if it's caught quickly) which is why you can find the OEM Denzo pumps on Amazon as it's a common issue on Toyotas from the late 90's.
@@pinkertonfld Yes if gas starts coming out of the filler neck yep it’s way overfilled and the gas pump not working correctly once the vapours hit the nozzle it should click off how they work
@@ryans413 Ummm, some cars I have owned the trigger clicked continuously because of something causing the trigger to switch off, not because tank is full. I would have thought it was purely a safety feature, not down to protecting the vehicle.
So frustrating to see the obvious diagnosis but semi understandable in a way that the customer doesn't understand but that's why the fuel pump clicks off so that you do not overfill as it leaks down into the vapor lines
I always fill only to the first click, but never knew over-filling could result in a flooded canister.
Diesel fuel pumps click off also, and diesels do not use evap, pump nozzles click off to avoid muppets flooding the forecourt I believe.
@@marksmallman4572 yes in the video we weren't talking about diesel not everybody drives a diesel I believe the majority of people that would overfill are diesel drivers like myself there is a return vent line to the tank to prevent that spillage from aggressively pumping out of the spout doesn't work all the time but there is one. 👍🤣
Car is in surprisingly good shape and CLEAN too. Remember you ran the first test with a full tank. Not recommended.
Nice that you stuck to it even when ideas seemed exhausted. Congrats on finding it! Didn’t know that overfilling can lead to all those issues.
Maybe guy will cool off and realize… what no one wants to hear, “what you are doing sir, is wrong”
Ray, you’re absolutely correct. I , over a number of years, topped off my tank till I ran on the ground
While traveling. Never listened to people tell me I shouldn’t. Never gave me an explanation as to why but that I shouldn’t. Week years later I found out why after changing the canister, valves and tank (good old Pennsylvania rust at the fuel pump orifice) I became a believer. Yes it is a Toyota Tacoma. Also, never used Dorman parts. Always original or from the manufacturer who makes the original. Your customer is just being stubborn and probably one of those e persons you can always tell but not tell them much. Have a great day. Good diagnosis.
Well you yourself weren't a "believer" until it happened to you. I expect this guy is the same, but there is no "broken" part he can be shown.
He has probably done this for a long time, so it sounds like a scam to him.
I expect he will come around when he does his own research.
Pity he reacted the way he did. I disagree with people quite often, but I keep quiet and inform myself before saying anything, since I am fully aware I don't know everything there is to know.
I made the mistake of overfilling gas tank on Honda Odyssey. My mechanic told me, "Don't do that!". So I quit. Problem solved, after I paid him to fix it. I realize most of you mechanics are looking out for us little guys, and I appreciate it. I'm a plumber, so I get a lot of the customer know it all headaches you guys do, and it ain't no fun, but the good customers make it all worthwhile.
No professional expertise on this repair, but I've been a DIY mechanic since the late 60's and your workflow and diagnostic steps seem very well thought out. I'm impressed as always.
Great work Ray. Australia doesn’t have the stringent pollution rules you guys have but trickle filling the tank to max creates problems I never considered. Love your work and the vids. I’m learning heaps watching how you tackle your work. 🇦🇺👍
I was today years old when I found out you could overfill the fuel tank! Thanks for that!
I never knew over filling a tank could cause any problem apart from spilling out. ( never owned petrol power later than 1991) Intimidating looking set up they have now. Outstanding diagnosis work. Thanks for the schooling. As for the customer.... too much pride, guess they will figure it out after paying a few times over to be told the same thing. Thanks for the upload. Most appreciated.
I am a mechanic and yes overfilling your gas tank can damage the charcoal canister (a device that catches fuel vapors). I suspect we will be seeing more and more of these problems because of rising gas prices (people trying to fill their cars to the absolute maximum because they fear that it's going to be more expensive the next time they fill up).
@@mathieulevasseur4082 does overfilling diesel result in similar problems?
@Andrew_koala TL:DR Blah, blah, blah
A friend of mine had the over filling issue I found out when I replaced a second charcoal canister I less than a year. He would click click & click again when filling the tank the second bad canister was full of raw liquid fuel, I explained why they call it a"vapor" canister. Good point.
Please move north. Thoroughness, competence, honesty and integrity all in one mechanic. We need more like you.
Once again. Exceptional work. Only the customer knows how many times he’s been told what you’ve found to be the problem and had the canister changed.
Thanks for explaining WHY you dont top off the tank. I had heard that but am guilty of doing that in the past. Now I know why thats a bad idea so you might just have saved me some serious dough. One click and done at the pump from now on. I've learned alot watching a truly great mechanic (YOU) Thanks.
I’m a licensed mechanic with a smoke machine this is very good diagnostic for every boneheaded customer honesty will give you lots of good lifetime customers.Look after the good customers who trust you and get rid of the ones who don’t
I can understand the guys feelings hes probably been told it's all the stuff he got repaired and what they told him to give him the confidence that it couldn't have been his fault.
I wish you were in Australia as you are the most professional knowledgeable honest mechanic.
If these customers watched your videos they would have complete trust in your work
Oh my!! Not being up front with you in the beginning turned out to be a clue to the end. I believe this "Customer" owes you and the shop an apology. You have a great attitude. Great effort on your part Rainman!
Well I'm not sure not saying he overfills is being dishonest. He probably didn't know that was bad for the car.
Problem with mentioning everything to a mechanic is that it can bias the diagnostic process.
@@Cheepchipsable I didn't mention anything about the overfill or dishonesty.
Being up front with the recent vehicle history is more of a benefit to the customer. Having to contact the customer twice for bits of vehicle history at a time is not beneficial to anyone. Then being accused of up selling.
It's to bad the customer has probably been treated bad some where else.
Rainman busted his butt diagnosing the problem. Whats wrong with a gracious "Thank You"?
My goal is to always be a great customer.
Have a great day! 👍
Fine piece of diagnostic work. I know far too many guys who would not get a code on a 20 year old car and just shrug their shoulders in resignation.
Thank you for this video Ray. After years of telling my wife that she shouldn't fill the tank past the first click, I now have video proof that I was right!
Sorry you had to work so hard for it to go that way. Whatever diagnosis you give, I would never doubt. Your truly an amazing mechanic!!!
I'm impressed how well you took it. I probably would have been a lot more upset at the customer. But you are right, sometimes people just need time to digest things and accept their own responsibility, it is human.
Either way, kudos to you for your great attitude.
I'd suggest a new transfer case and a blinker fluid flush
Don't forget the catalytic converter bearing.
Ya need a new Johnson Rod in there.
@@MattExzy everything is ball bearings these days...
@@MattExzy He said rod.. Huh huh huh.
When someone doesn't know what is wrong with their car, takes it to an experienced expert, then doesn't want to listen to the well performed comprehensive diagnosis of the issue because it was user error....
😖😖😖
Lol IT is another field of work where the customer does not want to hear "user error". I feel Ray's frustration.
You should really get the fluke magnetic strap for that meter. Comes in so handy under the car
You might want to send a letter to his mailing address in the hopes his family reads what's going on. Grandpa escaped in the Camry again and he's been trying to fix that same gas vent since 2011. He makes sure to let everyone know each year on the Christmas cards he sends out to overfill their gas tanks. "If it doesn't click 8 times, Grandpa isn't proud of you." Ray you've disrupted a long family tradition.
lmao... now that by far is the best answer. kudos.
😂😂😂😂😂
I have a 98 Camry for a work beater, and I used to round up to the nearest dollar. It kept giving me a check engine light.
Goodie, a solution, Ill be taking this with me.
Love the way you dug in and tested each component of the system. I know sooo many people that couldn’t do that, that call themselves good mechanics.
I wonder what the evap readiness monitor said?
I sure hope he charged accordingly for that. So many people say they wish every mechanic was this thorough but they don't want to pay for it.
Just a tip, you may hear the solenoids clicking and reponding electrically but they still may be leaking internally. had a 2014 ford escape and the purge valve would click when activated through the scan tool, however after removing the purge valve, smoke would flow through either way without impedence when the purge valve is supposed to be normally closed until electrically activated
wow, i think i'm one of the "perfect customer" you could have: I deliver my car washed outside, no mess inside and i listen to whatever feil was detect and whatever best course of action to repair. As i know that i do not know nothing about mechanics and autos, i tend to follow the expert on the matter. No absolute problem to take my responsability for my own ignorance, so i would love to have a personal mechanic like you! i would absolutely pay your fee and more with a smile, knowing you did your best to service my car!
I agree to sending the car clean inside and out to be serviced. I also keep the engine bay very clean too. I think it tells the tech I care about my vehicle!
Been through all the steps you went through including swapping a known good canister. The problem with this car is likely the overflow control for the fuel tank. They go bad on this generation car and when that happens and combined with a customer that likes to top up obsessively leads to this on this generation Toyota. You can see the control valve at the top of the tank when you ask your audience if we see any smoke.
I'm pretty sure I have the same issue with my GFs 1999 camry.
Love the videos. Keep up the good work.
This is accurate, the failed overflow valve is contributing to the damage of cannister as well.
Good demonstration of what can occur when one overfills the fuel tank.
Hi Ray. I haven't been watching long time, but I want to thank you for giving me the confidence to try to work on things I normally wouldn't try. I have never been good with mechanical things, but since watching your videos I have more confidence to try! My home AC started making noise, and I used your technique and what I learn from watching you to try to diagnose and work on it. I was able to pull out the control board and blower assembly thing and know what the problem is now! Thank you again for being so inspiration!
I'm not a mechanic, but love seeing you diagnose. I have learned that the key to diagnostics, is to have a plan of action and to follow that plan. Methodical. The average layman car owner would throw parts at it, upon free recommendation of the Auto Parts store employee and confirmed by a shade tree mechanic buddy. Enjoyable and informative....even for the non mechanic.
I can understand both sides of this issue. I had a Camaro that I was overfilling the tank, not knowing that was a bad thing. I replaced the canister, and when I stored the car for the winter, I overfilled it thinking I was protecting it from any kind of contaminates getting into a less than full tank. Well, to my surprise when spring came around and I started driving it again, there was the gasoline odor again because I had saturated the canister. I sure wished I would have figured this out sooner, now I needed another canister, and when the gas pump stopped, I stopped filling.
Couple tips you where right to fill the tank up for winter but really half full good enough anything less will cause issue. When you fill the car up and the pump clicks off your done it’s full the system all works together with the gas pump to tell the pump when it’s full. As you fill up the gas vapours also fill up the tank so as the gas level increases in the tank since gas is heavier then the vapours the vapours sit ontop of the gas as you fill up once those vapours climb up the filler neck and hit the pump hand it tells the pump you are full and shuts off stop filling at that point your done. If you over fill now there no room in the gas tank and those vapours gets saturated in gas filling the canister now and that can cause the gas tank to buckle under pressure. Another tip when your gas gauge reads a quarter of a tank left look at that as empty and go fill up the gas helps cool the fuel pump if you constantly let the tank run so low the gas light comes on it can run the pump hot shorting it life span.
So many people have been ripped off by crooked and lousy mechanics I can understand the customers mind set. BUT you are doing everything right! In the end it's the customers loss!
I really like your videos. Just came across them. I'm an auto body repair mechanic trying to start my own channel and run across all these issues. Please keep posting it helps our community of repair monkeys with your experience and techniques!!! Earned a solid subscriber
Great video! Very impressed by your diagnostic prowess. Way above my back yard mechanic pay grade. I also didn't know you can damage the evap system by overfilling the gas tank. Good to know as I am (was) guilty of doing that myself.
Not me man. I've never done that. Yeah-right ! ha ha have a super day.
Yep, screwed mine up in a Mazda 5 a few years ago. Learned a valuable lesson. Never ever did it again.
On a management course I attended with a group of others, a psychologist asked us to write down the two best moments of our lives, and the two worst. We were then asked to remark on who was responsible for the 'best' moments. and who responsible for the 'worst'. Close to the end of the class, the summary we were presented with, is that "we" always claim responsibility for the best moments (like personal achievements), and the worst, always down to "someone else", even if we'd set up the situation prior to the disaster arriving. The conclusion then, is that bad things that happen to us, HAVE TO assigned to someone else. This is a great example of proof that condition exists.
I've been working on and fixing computers for over 30 years. (386 + DOS days.) 6 months ago I got asked to sort out a fellas problem with a printer. He thought it would be a simple 2 minute job, which it wasn't, not least because of his peculiar setup. Anyhow, I got the same reaction experienced here. A fella who knows next to nothing about modern operating systems, telling me I was doing something wrong. Even if I had been, how was he to know? I was doing this as a favour, so the 15 minutes I spent on resolving the matter didn't cost him anything, but his pissy attitude will mean he won't be getting free help in the future. Seems I fixed the problem (I was told later), but I didn't get thanked for it either. Honestly, some people should come with 'health' warnings.
Everyone thinks it will be a 2 minute fix.
I've met so many people who admit they know nothing about a subject, then proceed to argue with you when you try and explain something.
My computer sales/repair/throw-in-the-trash experiences began in 1981 prior to the first IBM PC and PC compatibles. I could tell a ton (and the stories don't weigh much - at all!) of such stories. It's amazing when people build/assemble their own computers from ordered parts, can't get it to power up, and then proceed to try to tell you what's wrong when start to fix the problem. I'm somewhat to mostly retired now and can look back and laugh. Out loud!
this is interesting because some of the worst moments of my life, I blame myself for, where as some of the best I can think of, I definitely give credit to other people for. Is there something wrong with me? lol
