Thanks for the video. I had a PT cruiser with a misfire as well. Your troubleshooting steps help me quite a bit. I ended up finding a vacuum leak on the intake manifold with a smoke machine. I wouldn't have thought to use a smoke machine without your video.
Great job, Will. It's rare to see real-time diagnostics like this. Glad you're back!
Very thorough. I appreciate it, I've been a bicyclist my whole life, but for the past 5 years I've had this PT Cruiser. I could fix anything on that bike. I've got issues with my car, and it is time to go from zero to hero, and thanks to vids like yours, perhaps I can do that! Now I'm off to the next installment! :D
Wow best description. Of all this Info..appreciate the step by step 100%
thank you for the compliment!
Will - so glad you are back!! Great diagnostic video - very well explained. I learn something every time I watch your videos. Looking forward to part 2.
L,, llll,, L
I love your videos. I got hooked when my heads were cracked and I had to replace the heads on a 99 Chevy suburban. I didn't have much experience but I watched all your videos on the 350 Chevy which had 5 parts and that helped me tremendously. I had my laptop in My garage watching along. Thank you for all you do.....
thank you, that's awesome, feedback like this keeps me going, makes all the time invested worth wild, thanks again made my day
Welcome back Will. Very well explained video as always!
Fantastic video, great, clear instructions. Very valuable for DIY like me. Thank you very much.
Awesome video, Thank you, I have a PT Cruiser coming to my shop tomorrow with the same symptoms
Nice to see you back Will. Great analytic approach to a problem as always.
Thank you its nice hearing from you as well, thanks for the compliments wish i had my scope to demonstrate a relative compression check however it crapped out a few months back, would have been a nice demonstration as well thanks again
I just came across this channel. Wow what a resource! Thanks for taking the time to explain the diagnosis it really makes a big difference in learning to diagnose myself
glad you like the channel, your welcome anytime
Fantastic Will - you never seem to have easy repairs and that's why your one of my favorite channels. Glad to see your back. Thanks.
Thank you, yea i try to share the more interesting ones, i do get a lot of common jobs in as well but like you mentioned i hate to bore you with a ton of repetitive content, thanks again its appreciated
I totally agree, Steve.
Hi, nice filming and great consistent audio. Watched pt1 and pt2 and easy to see and hear.
I bought a 2001 PT cruiser that was garaged for 3 years, it's 2018 now. It was a show car and meticulously kept up with all service records. I got interested and looked on FB and offerup and see quite a few cruisers for really cheap, like a few hundred. Most have great bodies, maybe worn inside, but decent. Most have engine issues. Just looked at a 2001 similar to mine that had the same aymptoms. Garage told them to much to fix and it will start and run, but misfires, although at higher rpm it seems smoother. I was going to get is for $275 as a parts vehicle if nothing else, but like one reader commented it crazy that cars in basically good condition are junked because no one can afford to do repairs. I thought of making a stab at it with all the info for diagnosing the problem, just not sure what the parts would cost if it is a head. Guess I'll find out. Thanks again for the video and wondering if there is a part 3? Did you change head and continue?
thank you for the kind feedback and sharing with us. yes this complete repair is documented, i just added a link to each part in the video description
Great video! Looking forward to part 2. Glad to see you back on here.
thanks for the compliment, part 2 coming soon thanks again
Glad to see you back. I have a PT Cruiser I am looking forward to the next videos.
Thank you, its great to be back, i have to admit its growing on me lol and my other half is now thinking of holding onto it for a bit lol, part two is coming together thank you for following
great to have you back, Will!
thank you, its great to be back
very informative video...can't wait to see part 2!...welcome back Will!!
Thank you for the compliments, part 2 will be coming shortly, need to get to editing, believe it or not this is still in progress, this came in my shop Friday afternoon i shot while troubleshooting real time minus the editing lol got back on it today, thanks again
Really great video bud.Very informative stuff.You have a great day.
Bro I love how u say radiator, freaking legend love you bro.
You explain things very well.
grate video it is nice to see you back
Excellent diagnostics
Good Video
Back in the days when I worked in a garage, we would have had to remove the head after the compression test ,to pin point the actual problem
it was a small garage, doing the leak down tests is a great way to pin point the fault,
Thank you, i agree its nice to have a general idea and assumption of what to expect once the head is off, and thanks for sharing some of your past
Good video thanks a million it helped pull me through a timing issue tks ...
Nice 1 Will, good to see you back.
Thank you, its nice to be back
Excellent diagnosis
Several years ago, I ran into problem with misfiring. While doing compression check on #3 and #4, there was a lot of antifreeze shooting out of #1 and #2 cylinders. Took the head off and found a crack between #1 and #2. Remanufactured head cost me almost $400 at the time. After replacing it, had no further problem except massive oil spray caused by ruptured diaphragm in the oil sensor. Engine had been sitting with the head off while trying to get the funds to pay for the head and had been quite awhile before getting repaired. I made sure I removed the oil/antifreeze mixture and antifreeze so it may not cause damage to the inside of the engine before letting it sit. But oil sensor probably didn't take it too kindly. One day, I took off fast and then stop. When I stopped, suddenly the smoke blasted past me as if there was a bomb gone off behind me. Turned out oil sensor blew through the connector and flooded the exhaust pipes with oil.
Thanks Will. Glad to see you're back. Hope the life changes are for the better or at least tolerable. Tony
Thank you, its great to be back, life got rocky for some time thankfully i found someone to stand by my side and pull me back up
Amazing video easily the best i have ever seen!!!
Well said my pt has been misfiring and this guy made my life so much easier. This is a real schooled mechanic. Problem solved
Your videos are awesome! Keep up the good work
Thank you for the compliment, will do
I am writing this at 10:31 on your vid .. head gasket is my guess , or lower plen gasket . SUPER GREAT to see ya back man I missed ya !! Thumbs up ..
awesome thank you for the interaction i like it, great guesses, and thank you for the kind words means a lot
Like the others Will, I'm glad that you're back and truly wish that your life is a blessed one. Good demonstration of several techniques on analyzing the #3 misfire and hearing your thought process while you go through the steps. I always heard that the PT is a bear to do just the simple stuff and after watching you remove things just to get to the spark plugs, I'm convinced I don't want one of these cars. Take care Will and many successes in your life.
Thank you for the kind words, truly missed you guys, I’m set back by all the positive feedback and greetings I received, really means a lot to me and reminds me of the reasons I started this channel with hopes of helping others while trying to prove to myself I could do it, growing up turning wrenches has had a lot of ups and downs, in one hand I get the excitement/thrill of a successful repair, while in the same hand many hours, blood sweet and tears may have been invested for that outcome, some just fight the whole way while others go smooth, I’m sure you can relate this to many aspects of life,
on the other hand, you got a personal life that sometimes gets behind while the hours tick away, I always called it a dream I was chasing, then in a blink of an eye that dream can create a nightmare, or be held over you as one, in my case anyhow
it would take a book to lay it all out however my personal life took a heavy impact, I had to step back for a bit while trying to pick up the pieces, everything is looking up, I have more support and understanding in my life now than I have ever, im very thankful
robinsonsauto I hope you are doing well brother. Just try your hardest, and do your best.
welcome back , though you had left us. glad to see ya back
Thank you, never could, its great to be back thanks again
bon mecano,bonnes explications,good job
Great video. Cant wait for part 2
thank you, part two is in the works
My man.. Awesome job
Great to see you back making videos.
But more importantly, I hope your personal life is in good order.
God bless, and have a wonderful day.
Bob.
thank you for the compliment and kind words, things got rocky however they are looking up, thank you for the concerns, hope you have a wonderful day as well thanks again
Great video! Thanks.
i appreciate the compliment, your welcome
Excellent video and good to see you back :)
Thank you for the compliment, its great to be back
welcome back teach
What was that exhaust smoke coming from the center of the engine when you did the compression test (9:47 and later)?
Hope next part will be come soon,thank you and thumbs up
will do my best for you, i have started the editing process, to be honest this is still in the works, this vehicle came in Friday lol so what you seen was real time pretty much minus the time it took to edit, was back on it today, thanks again
Nice job
Thanks for your time for showing this great video
i do this kind of diagnosis so often. How do you guys charge for this inspecting time for the cause but not the actual fix such as replacing gaskets, burnt valves....
You let them know that what would be the estimate cost or bill them in the end after fixing the car ?
Sometimes i have some trouble with this diagonostic charge
Waiting for the part 2
Great demonstration, I noticed puffs of steam coming out of cyl 3 @ 9:45 when you were performing compression test, had to be coolant!
Thank you for the compliment and feedback, yes good catch, i notice it slightly as well once i got back near the engine bay, tried smelling it lol hindsight i should have pointed that out as it did get my attention as well, sometimes i just get so used to working alone i fail to cover every concern or clue i should say lol thanks again
Great video
thank you
Very informative video in real time, has me wondering if I have a valve issue at cylinder one myself as I changed the coil pack, spark plugs, and wires...injector seems to be firing fine but trips a code P3001 misfire cyl 1...thanks.
my hilux misfire the same way and I checked for sparks and coils and wires everything is good I thinking of a compression test that will pinpoint the problem thanks for your informative video I am waiting for part 2.
its always a good step in troubleshooting a misfire, another great tool for the arsenal is a lab scope, unfortunately my old bench top scope took a crap a few month back, once i get back on my feet it will be replaced for sure,
what i could have done with the scope is what they call a relative compression test, number 3 low compression would have showed up nicely, without removing a single part, just disabling spark and fuel,
just hooking up a amp clamp and cranking the engine over, each cylinder compression stroke will show a spike in amps as the starter strains to over come the comp. therefore the low compression 3 would have shown a less amp spike
I can't wait for that , thanks for replay
robinsonsauto hey robinson,
it is 2004 toyota pickup 4 cylinders its misfiring and have some vibration when start move and when ascending a hill .
i changed spark-plugs 3 times and test every thing and find nothing bad .
after this video i tested the compression and found the cause of the misfire .
3 cylinders around 165 psi and # 4-95 psi .
i pour an oil in cylinder #4 then i have 150 psi .
are there any way to fix it with out change the piston rings ?
This is great info but might be bad news for me. I started to get a #2 misfire code. happened all at once. yesterday at about 11:30am leaving work. i have checked everything and changed everything, you have showed me some additional thing to check... Thanks
John Gonzo What was causing it?
We test the coil pod and it tested fine but I suspected it anyway and replaced it anyway, it was the problem
I have always enjoyed your videos. Glad to have you back.
Thanks you i appreciate that, glad to be back
Awesome video great job!
I just bought a PT Cruiser and the previous owner said that when they installed a new transmission in the process they broke a sensor and now is causing the engine to overflow with gas n the car is not running due to that. Any ideas? Thanks for ur time!
Good to see you back posting videos. I am certainly interested in what you find when the head comes off. Hopefully it is just a gasket. You think it was time that might of killed the head gasket or head or maybe an overheat?
Thank you its great to be back, its hard to say for certain what caused the problems, however my main guess would be an overheating event like you mentioned
hey Robinson when are you going to release part 2 to the pt cruiser mis fire. youre video helped me identify the issue in my wife's 2003 2.4 turbo
Thanks matt. Do you have any vids on the turbo gt models glitching the pcm from over heat under the hood? I've seen that this can trigger p031 and p037 codes. What can you tell us? Thanks again
Look we had a good time you help me when I need it.
But it's over now and I have moved on yes o had the habit Bad it got in me but now I'm clean and although I don't attend any meeting
I can say
The Pt Cruiser/Pronto
Disease that almost ended me The Timing belt The Water pump.Radiator. and Headhasket along with The whole "Correct sensors"
Ordeal even the ECM repair
All that angst after the want all of it Gone I belonged lust after a PT Cruiser god bless you and thanks speedy
Pt Cruiser clean for over 6 month.YES.!!
Hello. thanks for your video. Consultation have a problem when it is regulating at a traffic light, try not regulate off or uneven .- a) I need if I can help where the IAC valve to clean it. b) where the fuel filter to change it ?.
Will I don't feel good that this car is probably worse than you thought but it does make me feel good that even the best professional can make minor initial misreads. I bought a car with a cooked engine cheap - ran just missed found out overheat cracked block- no white smoke coming out of muffler so thought probably ok
Great video Will. Looks like there's sludge present under the valve cover, or is that just a camera effect?
thank you for the compliment, actually i didn't take notice to that now that you mentioned i looked its not so bad, this was shot on Friday the same day the care came in so what you seen was pretty much real time lol i noticed a few steps i wish i had covered, one thing i did fail to mention is i dont see any trace of coolant in the oil, thanks again for the interaction its greatly appreciated
Mine barely even starts but when it does, it'll do this. Distributor, spark plugs and spark plug leads have all been changed and it still does this
Hey Robinson question maybe you can help me out on this . my engine vibrates, enough to feel it in the steering wheel, between 1000 - 1400 RPM or so. This happens whether accelerating in Drive, or reving the engine gently in Park or Neutral. In other words, it's always present.
Another question is when driving gently when the transmission shift to 4 gears the rmp will drop lower and RMP it will start to surge too then it will go up to where it need to be to shift next gear. If I press on the gas a little hard it will be normal . Could this be a faulty map sensor ?
2005 Dodge Durango 3.7 with 124,000 miles . thank
same situation I'm in rough idle
what check engine codes did u have?
Great video and nifty diagnostic work. I was trying to pinpoint the cause and end up confused. I want to predict the head gasket is leaking due to a blown gasket or warped head. A cracked head, perhaps. I would not think a cracked block would also cause the exhaust seepage. A tech posted to another video that 99.9% of the time it is a pitted valve seat when there is a compression and misfire issue on these PT motors, but this would not explain the coolant leak. Part 2 should be interesting. Thanks.
Thank you for the compliment, i hear ya, thought i had it figured out a few times then got thrown for a loop lol, always an adventure it seems, your correct they did have valve seat issues and i was leaning hard to that being the cause to be honest, then once i noticed the coolant system building pressure i had to step back lol my hope at that point is the previous owner didn't cook this engine, thanks again for the feedback
That's a good demonstration to people why a bad head or head gasket can burst your radiator, especially a really big leak into the cooling system.
You can hear lack of compression from right at start up at 01:15. No audible strain on starter at TDC of a couple cylinders.
Great troubleshooting! That car sure is a pain to get to the engine though. Should be interesting to see the results
Thank you for the compliment, yea i agree its a tight one, part two is in the process
Great video I hope my dosen't go that far but it's got a misfire.
I have an 09 pt cruiser 2.4 when I do leakdown Air comes out the exhaust and when I do a compression test the third cylinder has no compression even when I added oil u think it’s still just valves?
I have a 2001 PT cruiser it starts but as soon I put on idle it chuts out what do you think we can check on it
Enjoyed watching your 3 part video on the PT cruiser, just broke the timing belt on my 2008 today and found it has a non interference engine and may have bent the valves, does it always cause valve damage in these engines when the belt breaks?
Most times yes. unfortunately
It is an interference motor not a non-interference motor a non-interference motor would be very old or belong to a lawn mower most engines nowadays are of the interference type meaning that when the belt snaps the cam free spins away from the motor and if a piston comes up when a valve is open boom but this doesn't always happen and if you didn't hear a shit ton of loud noise or anything like that you may be all right just check your compression
Mine snapped put a new belt on it and it runs
I am trying to figure out why my 01 pt cruiser won't start has fuel and fuel pump is good new spark plugs and is getting a spark any suggestions as to why it won't start?
welcome back we were worried about you dude!
Thank you im glad to be back, and thanks for the concern everything is working out
how changing the injectors in a pt crusier 2003 2.4 turbo is nescesary closed the gasoline pump
My 08 pt cruiser sounds like it back fires through the breather when you give it gas going down the road. Sounds like it pops and crackles. Any ideas
Will, find a cliff with rocks at the bottom and jump those 2.4 suk azz to do heads on. Remove the inner timing cover and then the cams to get the head bolts out what a pain, not horrible... But u r doing it in a pt cruiser. Bad enough they suck to time as well. Ive had more run ins with these than i care to remember. Good luck my friend its about as bad as doing a water pump on a 2.7 in a stratus
my gf has a 2004 pt cruiser 2.4l turbo and the check engine is on and a cpmuter was used to diagnose the problem and it was code P0304 and the spark plugs and wires were changed. the check engine light will blink on and off when in idle and then will stop after accelerating. need help..
I had a misfire on Cyl #4, turns out that the intake gasket on the block side of the intake had developed a crack & it was sucking air.
Mine is making a racket and just started doing it today RIGHT after a CAR wash... Damnit! LOL.
Its been making some kind of weird noise for a while but I did not think it was the internals. Thought is was an exhast issue. TUrns out it may be infact the head. Its making a racket it seems and the idle is REAL jumpy. Not sure whats going on. But at this point? Mechainel failure is on the menu. I got close to 300,000 miles on the car so no biggy.
Pretty obvious to me that No. 2 not 3 had some issues.
How about a 2004 2.4 toubo-charged motor with the same over-heat problem.
can any of these errors on my pt cruiser cause it not to start? errors are p0508,p1193,p1491
Greetings, I really like your videos. I am a guide to repair my Pt Cruiser 2007. I have a problem and I need your help because I look for the fuel pump fuse in the fuse box and I can not find it. The cover of the box only has numbers but does not indicate which is the fuse of fuell pump. I would greatly appreciate the help you can give me. Thanks in advance.

was there any troble codes present ? just being cuirest lol
I WANT YOU TO SHOW ME SOME 2009 DOUDGE JURNEY REPAIR THANK YOU
hi, do we need to remove intake or just look for air by removing oil cap.. 2) i am not sure why air is coming out in number 1.. does 1 and 3 have some path, or 1,2,3,4 all have path and just because 2 and 4 is closed air is leaking to 1 by least resistance.. do u also recommend me to remove valve cover and intake to be sure..
on this engine the upper intake plenum needs to be removed to gain access to the spark plugs for testing, most other engines do not require this step, 2, all the cylinders share the same path to the exhaust, through a coming exhaust manifold, cylinder 1 just happened to be on the exhaust stroke during this test meaning its exhaust valves were open opening the path to the coming exhaust manifold creating a path of least resistance as you mentioned, i take that step to assure the cylinder being tested is on its compression stoke meaning all the valves are closed, gives you a visual
Thanks make sense, for a moment i was thinking why the smoke was leaking past cylinder when both valves are closed. then i realized because it is defective it is going past the exhaust. thanksagain for ur time. your videos are very unique not repetitive with same information.
Not sure why but my intake is metal and I don't have to take it off to get to the spark plugs
Need help. I have a 2001 pt cruiser 5 speed. One day it started acting funny, by funny I mean it kind of felt like I wasn't getting enough gas. It felt like it wanted to stall on me. When finally it did. I replaced the fuel pump and filter, and it didn't fix the problem. So I changed the coil pack. It started up, my dad took it for a ride, and it completely died on him. Ended up having to get it towed him. So I bought new spark plugs, it started right up but could tell it was still misfiring. The whole time all this is going on, there is no check engine light and no codes. We changed the cam shaft sensor and the check engine light came on, saying cylinder 1 misfire. I have since replaced the crank shaft sensor as well and it still doesn't want to run. It is starting up, but once you start to drive it, it starts stalling out. Please any ideas would be great. Sick of buying parts that aren't the issue.
I'm having the same problem on a 2002. Have you found anything? Contract me at nomad1ne@gmail.com thanks.
Looks like u know what u doing I got a 05 pt cruiser with tha code P0300 please help
My wife has 05 pt and when its at red light or stop sign turn ac on the car bogs down do you have any advice. Your videos are great pls do more
Ever figure this out? I have a 05 pt cruiser that does the exact same.
Chris Slatzer 03 PT with the same issue. Ever find a solution?
p0300,p0303,p0137,p0138 no coolant leaks but yet I have coolant loss car runs fine under a load.
Nvm cyl 3 was 25lbs all other cylinders 180 and air comes out of exhaust on cyl 3 at tdc
What was the prob is there a second vid ?? Nice vid
part two will be up soon, thanks for the interest and compliment
I haven't watched the series yet, but I'm guessing it's a cracked head
I need parts of p t 2003 m how i can buy.
Does this vehicle have any redeeming quality? Compared to Corrolla or Civic, this looks like such a pain to work on and on top of it you have major engine problem on a relatively new car. I can't think of any good engineering reason as to why the engine was designed the way it is on this car. What are the pros of such a design?
Thats a great question, i must say its pretty roomy as far as sitting space compared to a more compact car, and just the fact that the manufacturer stepped outside of the box with body style and concept seems to be appealing to some thats a big risk, however as you mentioned the engine compartment is cramped, changing up the engine layout had to be a task as well for them, i must admit its not as bad as it appears sure compared to most 4 cyl, it seems tough however i would much rather tune this up then say a carivan v6 rear bank, however as you mentioned its a poor setup in many aspects i agree, peppy engine as well for a 2.4
thanks! The vehicle itself is roomy but is the engine compact compared to other similar sized ones? for example, does 2.2 Honda occupy more room in the engine compartment than this one? One of the advantage of a modern 4-cyl 16valve engine is the easy maintenance of the spark plugs as long as one has deep socket or the valve cover gasket. By putting the intake manifold right over the plugs, this engine makes a simple job in to a nightmare. Even some of the V6 (3.5 Honda J series) allows easy spark plug changes on it without having to take off the upper intake.
12vgs8606 your welcome, yea i hear you, i was just thinking outside the engine bay for redeeming quality's, because as you pointed out some simple tasks have been made difficult, due to the compact engine compartment, therefore in that sense your correct, the engine bay rates real low with most other comparisons
if valve is slightly bent compression will be 0.
Tengo un ruido en mi pt cruzier lo escuchó un the top can help mi
Mine just blew a head gasket at 70,000 miles. Never overheated
they are bad about that
Chrysler Pt cruiser 2004 pcm reprogram
These have a double layer steel plated gasket, chances of it blowing is very slim..You will warp the cyl head before the gasket blows. Im almost willing to bet the car was overheated from maybe a fan failure without you knowing...Im a Chrysler ASE Master tech.
overheting. ..check. Cool system... fan
3 speeds. thermostato........
see u after a long time. great video.
Thank you for the compliment, its nice to be back
Been a month since your last video. :(
