I HAVE A 2012 GMC TERRAIN.2.4..REALLY HELPED THE PCV SYSTEM...COLLECTS ALL THE OIL GUNK FROM GETTING IN MY INTAKE MANIFOLD..THANKS SCOTTY ..EXPERT ADVICE..
Michael B. - I wouldn’t buy another DI Volkswagen if it was half price. I bought a Toyota particularly on Scotty’s recommendation. But ha I noticed that too
Well sure people laugh at a toyota for its vanilla flavour but they stayed away from Turbo and gdi, hence the proven old school reliability. Play it safe.
I bought a 2002 Chevy Malibu cause I wanted to support Detroit. Five years later, the car was having throttle issues ( revs up at stoplights ). Took it to the dealership. They couldn't reproduce the problem. Paid the 1 hour labor fee. Am I trusting this car to haul my wife and 2 year old around the mean urban streets of Los Angeles, at night? Abandoned domestic cars after that. Vanilla Toyota for my family!
LOL! EVERY one of our Ford vans and trucks made 300k all the time. And we drive the piss out of them! Plus we don't even change the oil every 3k but every 7,500 miles and very minimal other maintenance. The myth that only Toyota's break 200k on an engine is so silly. Those snobs don't even drive their vehicles as hard.
A caution on using oil catch cans in winter: they can freeze up and block the PCV line. The can is fine all year until you get freezing temperatures, then condensation starts to build up in the can. You actually get more water than oil in there in the winter months. It needs a lot of maintenance in a Canadian winter and becomes a hassle because you have to let the whole engine bay heat up hot before all the ice will melt so you can drain it. If ice builds up in the actual lines to the can you can get a blockage. Happened to me and blew my valve covers with the pressure. Happened again and blew my engine. I'm just leaving off the can in the winter now, not worth the hassle and risk.
+428ghost - If you are " Catching " a lot of moisture... More likely you have a Coolant Blow-by / Head Gasket Leaks! NOTE: If anyone here have the same.... Try Bar's Leaks Head Gasket Sealer, before it get worse! I did that with my Dad's Car and Truck.... OMG.... Now I only catch oil. Before, I was getting like 1 Ounce of moisture every 100-200 Miles! I made a few Video on my Channel if you want to see that!
get an air oil separator that has built in engine heating to prevent freeze up. Best solution. usually just have to run it off the throttle body coolant hoses
Hmmm, a serious problem in cold parts. What about a tee close to the PCV valve with the middle of the Tee being kept closer to the engine and in a way that goes down the engine block then putting a clear container almost level with the sump but again where the engine keeps it warm? A tap under the container let’s you drain it away once there is enough to make it worthwhile. Could be hard to find a spot where it’s not too hot not too cold. Customers buying a car should not have to do makeshift things like this, the companies engineers are paid to do a job, why can’t they design a solution to this? It annoys me greatly and worries me as well: if they cannot work out a solution to this then how good is the rest of the engine. Just like DPFs’ Diesel Particulate Filters - on the Toyota Landcruiser Prado in Australia with the 2.8 engine they have stuffed the design, why did they not look to the European vehicles and modify their solutions? Anyway this is just a thought. Good luck with this issue.
Scotty, I remember back in the day when most cars vented the crank case thru the tube down the side of the block to the ground under the car. This left a black tar stain on the road about a foot and a half wide that you stayed the heck away from if you were riding a motorcycle lol!!
I run an oil catch can on my 2011 Supercharged Wrangler. I empty the can about twice/year and it's TONS of gunk always in it. That's what we're keeping from going back into the intake, folks. THESE WORK! I'm installing one on my 2019 BMW 330i, as I just cleaned my intake (GDI engine) and my valves were CAKED UP BADLY! You need a catch can on a GDI engine.
The exact tech we've had on small recip aircraft engines for 70+ yrs. Works great and, I even have a secondary catch can installed after the air/oil separator to save the lost oil.
Isn't that a bad idea considering it is actually a (even if miniscule) oil water fuel mixture? That would lower the viscosity of your engine oil. @@daverossiter717
Impalaman's Garage it’s about business make a short lived engine so we’re forced to buy a another car to keep money and production moving in an endless cycle.
Hey Scotty, I purchased “M7 Racing” oil catch cans for both the turbo side and for the PCV side for my MCS r56. I notice the cans aren’t baffled with anything. Should I let it be hollowed the way it came or should I put stainless steel mesh inside or some type of material to help it filter better? Seems like no one really knows definitely what is safe and what isn’t out there on the internet. I would trust your judgement before anyone else. May you pls make a suggestion. Thanks again God Bless
Thanks, Scottie. Seems like the emissions control systems on GDI engines would be screwed with oil from the combustion products from oil blowby (and oil coming down the valve guides). Another problem with blowby is the blown oil seals on the crankshaft, which occurs when the PCV system gets completely clogged (due to poor design) and the blowby pressure has no where else to go. Case in point - the GM 2.4 L Ecotec engine, the engine design equivalent of the disaster known as the Chevy Vega. Thanks for this video and your opinions, and thanks for continuing to make them brief and to the point.
@@johnchandler1687 I keep it that way too, mostly so the wife and anyone else visiting doesn't come past EITHER garage door.... it is my island and I cannot be bothered while I'm there. Only downside is I have to stay nimble and limber in case I need to get anything
UA-cam recommended me to watch this video today (Jan 29 2020). If my facts are correct I recall Scotty covering in a previous video that newer Honda engines going from 2010's and upwards are Gas Injected Engines. Again recalling Scotty's little news bits Honda is releasing a new synthetic oil sometime in 2020 to combat the carbon build-up on the pistons and the rods. Let us see what unfolds as 2020 keeps rolling along.
Scotty absolutely love your vids. Learn so much about history of engines and problems that occur with engine design. Never realized how clean the valves stayed by injecting fuel directly into the intake valve system with direct injection. Hoping to soon modify a Buick 1963 215ci V-8 to direct injection with some Rover parts. Now I know exactly how I want to introduce the fuel to avoid problems. You are GREAT!
Eh...it comes with the territory. Aluminum block engines, cylinder deactivation, fuel injection computers...the early ones had problems. It doesn't mean they weren't good ideas, they just weren't tested properly before release.
Most of the time it's not their fault. Automakers task them with speed of assembly as a first and foremost goal, with the fewest human hands on the work as possible. Often times engineers will come up with a beautiful masterpiece of engineering but a marketing guy will hore a 'value engineer' (thats a real job, google it) who will take everything good out of the design to shave a few cents off production costs, or to use existing parts so that they can save from having to make new tooling, or simply the logistics of shipping inventorying or storing new parts, or simply removing as little as one production step. GM is notorious for this. To this day they use the same delcotron alternators that have a fatal flaw of blowing up if the battery's ground happens to be loose, GM locks can be serviced by the same kit of parts all the way from 1934 through 1994 with the addition of just one single part. They have keys that are all dimensionally identical as far as keying specifications go starting with an "A" blank through a "K" blank when they switched to a double sided key in 1994. The manufacturing process in 94 used the same metal stamping tools from the 30's. The only change was changing the setup of the milling machine that makes the grooves in the side of the key to slightly different locations. Even their ignition lock body castings were reused, In the 70s and earlier the locks slid into the steering coloum and snapped into place. Problem was they were easy to yank out with a slide hammer, so they stopped putting in a spring loaded retainer and instead machined a groove in the side to hold it in place with a bolt! Guess what, even though the spring loaded tab isn't there anymore nor the slot machined for it to go into, the spring is still present staked into the side of the lock body even though it had no function for over 30 years! Funny enough The company that makes GM locks, strattec, formerly Briggs and Stratton also makes chrysler locks. Inteterestingly enough the double sided gm keys from 94 on are a mirror image of the chrysler/dodge keys from 97 on except the chrysler keys are a tad thicker. That seems coincidental but it's not. When strattec's dies for making GM keys get worn out, they flip them around backwards, run a broach through them, and then they can make chrysler keys. All that so they can use a die that probably cost 5,000$ to make and can produce millions of keys, and do a small mod to it and flipping it backwards in a machine to produce millions more keys for another one of their customers! The same goes for engines and more. Often times this can cause problems down the road and or make things far harder to fix, but that is of no concern to people who make and sell cars, if it saves those people a single red cent they are going to do it!
+Willy Automotive Yes, even a penny. Look at the ford focus, there are like 5 million of them out there and everyone who has ever worked on them knows ford and mazda cut a lot of corners to pinch pennies here and there on them. 5 million times 1 penny is 50 grand. If you save 100 pennies over the whole car, which is a great underestimate you save 5 megabucks. That's a lot of money that the company gets to keep as profit.
SCOTTY must be SMART GUY he bought same exact Catchcan as i have on my car. it worked immediately from the start, on very first drive of only 8 km the filter was already wet with oil
I have been running a catch can on my 3.7 mustang, between oil changes (every 5K) I collect at least five table spoons of oil. I've been running one for about two years and I have probably kept at least a half of quart of oil out of my intake. My engine is not forced induction and I don't drive crazy. I do drive spiritedly from time to time but I don't abuse it.
I so much enjoy Scotties videos!! I would give almost anything to have a good mechanic and HONEST mechanic like him where I live !! He or she would make a killing
Thanks Scotty! You convinced me to order Catch Can (via your affiliate link) to my Hyundai Santa Fe with GDI engine, in the long run it's cheaper to install $35 catch can than use CRC intake valve cleaner $10 per can
Be sure to replace the hoses that come with it (assuming you got the same one in scotty's video which I also have) with new more resiliant fuel line (Can get from autozone by the foot). Also get you some hose clamps, and your good to go! Really like my catch can. Easy to install and maintain.
On many older cars without a pcv system, we called the crankcase vent tube to the outside air a 'road draft tube' as that is what is was. They actually used physics back then. Not all older cars were so lucky.
Ever since I purchased my 2015 Ford Escape with 1.6L ecoboost, I looked for any advice to maintain my vehicle using UA-cam. Saw my first video of Scotty and absolutely enjoy his videos, and respect his knowledge of what I might need to keep my vehicle running. After watching a few videos regarding the engine installed on my vehicle, I've sometimes wished I purchased something different. After watching this video, I have since purchased the catch can as recommended by Scotty hoping that it will help with excessive carbon buildup on the valves. Anyone have a description of what lines to connect the catch can to? Look under the hood, and say to myself that it doesn't look as easy as I thought it would. Just want to make sure I'm accessing the correct lines so I don't cause myself more problems. If I know exactly what to connect it to, I am comfortable installing it. Thanks Scotty. From a happy subscriber.
Well Scotty, you have another excellent video that can help owners save thousands. This PVC Catch-can is a cheap, less than $50, prevention item that should be done by thousands of GDI owners a.s.a.p.! Make sure you get a decent pressure capable can with a heavy screen to keep the water/oil at bay, coming through the PVC system. I do like the can models that have a drain on the bottom with a drain valve. Great idea, great video. Keep Rollin'!
Hi Scotty my wife has a PT Cruiser & later down the track I went & took the top off the air filter box & just to check the condition of the air filter & I was quite shocked the air filter was covered in oil & I took the whole complete air box out & cleaned it up & took awhile to clean all the oil out of it & then I thought of a solution & I cut the cut 2 of air breather hose & mounted 2 breather filters on each end of the breathers & I thought that would work & put in a new air filter back in the air box as it was nice & clean & having those breathers on the end of the 2 breathers was going to be ok but I was wrong & when I went with my son to take the PT Cruiser to a garage to get to new tyres fitted to the front to get a Warrant of fitness & noticed oil on the concrete floor from under the PT Cruiser & noticed the oil over the rocker cover & had come from the 2 breathers & I went oh no & I'm going to have to get a oil catch can the mechanic that was there I told who was Tony & that I will need to get a oil catch can & the one that Tony was going to get was too big & so I'm going to have get an oil catch can from AliExpress & the oil catch cans here in New Zealand range from $109.00 & $326.00 & up to $858.00 & that is by way too expensive & may have to try AliExpress Kind Regards Peter & other than that the engine runs fine & I know it's got blow by & I can't afford to do the engine up Scotty
Yeah, never buy a VW...my 18 year old Golf Mk IV has just clocked over 265,00kms. It runs like a German clock, apart from standard servicing and maintenance, all I've had to do is replace the fans. I gives me great fuel figures, and laps up my 1000km/week commute. Every manufacturer has good and bad models. Scotty obviously loves his Toyota, and I get the fact that it's reliable. But for people who actually want a car that handles and is fun to drive, a Corolla is just white goods on wheels. Different strokes for different folks...
i had an old Toyota... it died. Also my profile pic is my friend's 92' Camry that blew up. I don't think they are bad, just like anything, they still break. but i do agree with not buying a Volkswagen
japanese cars have good engines and horrible interiors.german cars have good engines and nice interiors and good handling but not so cheap to maintain.once you drive a german car you wont like to drive anything else.
I've driven and worked on many German cars (VW Jettas, golfs, BMW 3series, older 7 series, Audi A4, Mercedes Sprinter maybe others) they all had a nice ride (except the sprinter and bmw 3 that the rear subframe broke) and decent interior but i liked my interior on my older Cadillac much better and VW interiors seem to always smell like crayons and have the weirdest cup holders for no reason and always break. 1990's Passat cup holder is the worst i've ever seen for design. Also the 20v 1.8T engine is terrible. The main reason i don't like German cars is because they are so hard to fix, it's like they make it hard to work on on purpose
I have a GMC Sierra 2015 which is GDI and I don't know if General Motor have thougth about this problem at this time but when I bought it in 2018 I didn't take a chance and already installed one. It surprisingly how much sludge it can catch in little time.
Actually find this video to be extremely helpful, my vehicle have had a string of carbon build-up related issues recently, hopefully it will be helpful in limiting future problems at least slowing the progression.
That's a good idea Scotty! I think I'll purchase one for the 85 Ford F150. it has blow by where the rings are worn. I think that would be a good idea. We just run a rubber hose pointing down on it like the diesel engines have, but think that might be a better idea 💡. Thank You Scotty! I appreciated everything you do on this channel.
What about the old system used that vented the crankcase vapors into the air cleaner housing? This worked pretty well due to the larger surface area of the pleated-paper air filters. The air cleaners would normally be changed regularly anyway, so this seems like an acceptable solution that would work well now with DI engines.
I have a 2016 Audi A5 (2.0T) w/GDI. I installed a catch can when it was basically brand new. Initially, it did capture a little oil. Perhaps it was due to engine break-in? After a few hundred miles, the catch can never has any oil in it anymore. It's just dirty with a dry residue. Is this normal? The engine currently has 17,700 miles on it.
Mr Kilmer, I wanted to thank you for this older post. I found it to be one of the most informative automotive post I've ever seen. I hope you're enjoying your well-deserved retirement sir.
I dont call myself an expert by any means but I do own a 2018 direct Injection car so I will speak from experienced. I've been doing my own work on my own vehicles since I was young and have been tuning cars ECU for the past 8 years. Catch can alone doesn't get rid or slow down carbon build up especially with engines running with egr and tgv systems. When I checked my intake valves at 22k miles with catch can installed at 1k mile, it had tons of carbon build up on it so I had to do a tedious job of walnut blasting the carbon off. I installed an Air/Oil Separator, did a tgv deletion and an EGR deletion to slow down the process of the carbon build up and retuned my car's ECU to run properly. You will never totally get rid of carbon build up from a GDI OR DI motors but you can slow down the carbon build up by doing those things mentioned above.
Toyota's D4-S direct and port fuel injection is the best of both worlds, power and fuel economy of direct injection, clean intake valves and low particulate emissions of port injection.
To me it looks like double the number of injectors to break and/or get clogged up, plus the extra associated wiring. I can't argue about the improved fuel economy and performance though....
This is a great and perfectly explained advice video. I wish all youtube publishers went straight to the point like Scotty here. I nominate Scotty for an Oscar.
Hey Scotty, I hope you can find the time to answer this question for me. I have an MK6 Golf R that I have been considering getting an oil catch can kit for. All the full kits come with a block off plate/ adapter for the original pcv and warn of possible freezing in cold weather. They advise cleaning once a week when cold and to completely remove it and install the original pcv when temps are below freezing or you could potentially damage the seals in your engine. Is this a real concern? What are your thoughts on this? Thanks.
It does, mileage will drop and carbon deposit reoccurs via fuel. When oil is burned it increases chamber heat for an even burn of the fuel. If that oil not present the fuel doesn’t burn clean and you are where you started.
Jack Torse You know probably increases HP only mildly, I know with my race Kart and probably other race cars they have them, just so your not burning the oil as it is more of a dampener on the combustion process. Really these are here like Scotty says for emmisions.
The irony of this whole GDI / Gunked up inlet valves scenario is that we go to the effort of filtering and cleaning the incoming air for the engine; so if it was just a straight intake to turbo to inlet manifold, the air would be perfectly clean (relatively speaking) and there would be no gunking up of the inlet valves at all. But we (automotive engineers, that is) decided to recirculate all the gunk from the cylinder head back into the engine intake again *POST* air filtration, without considering that it might need to be filtered or cleaned first, and may cause issues down the line!! Very big fail.
So, you are proposing to have the PCV to dump somewhere outside of the air filter? And let the engine’s air suction draw the air through the air filter? Well, I think the oil from the blow-by will permeate through the air filter. And it will get on the MAF sensor and foul it. And still get into the engine intake. I suppose maybe if the air filter was redesigned to handle the increased amount of ail it would see.
Hi Scotty, does that mean that if you have an old clunker that consumes oil, instead of having to change the catalytic converter every time you pass the state inspection, you can actually put a catch-can and make it last longer?
The 2.4L Equinox has been designed to prevent a catch can installation. In fact, it's been designed to prevent service of the PCV system all together. They even designed in a trap on the makeup air side so if your vacuum side becomes clogged, the water vapor will freeze in the makeup side and destroy the engine. Genius right there.
Adam McGrath poor decision! U bought foreign plus a less sophisticated motor. Ford & Lincolns GDI turbos use dual type injection no carbon on Gen2 ..really was no carbon on Gen1 Ecoboost. Buy American!
Although operator maintenance and oil and filter choices can account for 30-70% of an individual vehicles life span, the quality of the oil pump, the quality of the valve seats, piston ring design, etc makes a bigger difference. Although Ford does an above average job with their trucks there is a real reason they anounced they will stop making most of their cars and that is not due to operator neglect. Consumer Reports annual car guide based on 500,000 to 600,000 reader surveys doesn't lie. I've been looking at it since 1987 when I got burned on a Chevy while in college. I encourage everyone to look at the guide. Pass on what the writers write as all humans including myself have biases.
Pretty much if u have a Kia or Hyundai you need a catch can. I have a genesis sedan v8 though it is not a gdi I still have to get a catch can because carbon build up on these v8s
Its also worth mentioning that if you drive a turbo car your intercooler will turn into a catch, so a good idea to have a catch can even if you don’t have direct injection.
Hi Scotty, A question: I am at least as old as you are and yes I do remember the old cars with the down draft pipe to dump the crankcase pressure directly out into the atmosphere and the small amount of smoke they emitted.. Which makes me wonder if we would or could just bypass it entirely now also and dump the pressure overboard (as was done in the past) and eliminate any need for a catch can on direct injection engines and eliminate the need to remember to empty the catch can. Sometimes like you I believe the simplest solution is often the best solution. Like you I also miss roll-up windows and vent windows on our side windows, manual transmissions and the old fresh air vents down near the floor on the drivers and passengers sides of our vehicles.
Love this guy. But wish he would talk a bit more about diesel cars... You see I'm from Portugal and all we have here are compact diesel engines...and I think they suffer from the same issue mentioned in this video and even worse being all the diesel cars turbocharged. Still I enjoy watching your videos Scotty even though I don´t have a petrol car :D
Alex Arriscado Vws tdi likes to clog the intake with goo. Either get a retune to delete the egr or do an intake cleaning every so often. I did it on my 98 Jetta by removing the intake and cam, and using a propane torch to burn the stuff out of the intake manifold and intake ports. Then since I was cheap, I made an egr block off gasket and lived with the check engine light being on, I didn’t want to retune. Occasionally I’d do a scan to make sure the light was on because of the egr and not more codes. I cleaned mine at 130k, and I could barely get my thumb down the main intake hole.
This is well-known on my platform, the Mazdaspeed 3/6 (turbocharged, direct-injected engine). One of the keys is this: if you put this on an engine that has 20-30k miles on it already, you're still going to need to pull the intake manifold and walnut blast the intake valves because accumulation has already occurred to really start off with clean valves. If starting with recently cleaned valves or a new engine, this will definitely help mitigate accumulation, but not stop it entirely due to EGR systems also putting oily air over the valves as well, in many engines. If you really want to address this, installing a water-methanol injection system will not only steam-clean the combustion chambers, it'll also keep the intake valves very clean. Additionally, it lowers cylinder temps, raises functional octane (M1 methanol is 116), and allow more boost and timing to be run if you're going for performance tuning on your setup. Finally, the evaporative cooling effect of methanol significantly lowers the air temperature entering the engine, thus increasing oxygen density and facilitating even greater power production.
You seem pretty knowledgeable with engine mechanics so any thoughts on Honda's current 3.5v6 in Odyssey regarding carbon buildup? Do you know if Honda has addressed the DI problem like Toyota or Ford? Thanks
@@tjsullivan4793 Not sure about the Honda engine, sorry. Most folks have taken a hybrid injection approach, utilizing both PI and DI, which completely addresses the issue. You see this in the FR-S/BR-Z engine, for instance. Sorry, wish I new more about that engine.
Hi Scotty I love your videos and learned a lot from. I got a new 2021 Explorer with the 3.0 v6 twin turbo engine. I wonder if that engine needs a catch can ? Thank you for your help. And be awesome as always !!!
Scott, Following your advice, I'm shopping for an oil catch can for my 2012 duramax equipped Silverado 3500HD, and my 2022 Mitsubishi Outlander ES. Both are direct injection, the Outlander is normally aspirated. Any thoughts on what to install? Also, temps in my area can go to -40.
Just to let you know Scotty, the reason they didn't put them on at factory and didn't notice the problem is because valve on gunk will not show up in a 500k mile torture test where its continuously running. What builds the gunk up is the constant idle, accel, decel function with the warming up cycle and cool down cycle over thousands of miles that creates what has been a problem on some of the DI motors in the VWs, Audis, Bmws, and the slightly older Ford Ecoboost motors until they also did the Dual injection system with port injection and DI. So anyways the reason they didn't realize to put on a catch can system from the get go is because when they have their cars in the testing facilities running for 200 hours straight it doesnt give the environment that will create the build up of carbon.
Seems logical - making cars less polluting has led to making them break down. This takes them off the road. Sooo logical. And then you buy another. Which then clogs up just like the last. This is the first video I've seen about blow by which shows the catch can itself. Very simple. Diesel tuners recommend them?
I bought a 2019 Mazda CX5 non turbo for my wife a few months ago and started thinking along the lines of a oil catch can. I did some inspecting first. I pulled the three hoses that connect to the throttle body and ran a Q-tip inside each hose and didn't find any oil residue at all inside these tubes. The car has almost 4 thousand miles on it so I suspect there would be oil residue inside one of the tubes. Looks like Mazda did their own research about this problem while designing the SkyActiv engine.
get those BS garden hoses off the cans and replace with fuel hose or better....also alot of manufacturers are NOT using the dual system that Toyota/Lexus is using....most dealers won't know...so used car buying requires alot of research beforehand even if it is a 2015-16 car.
Toyota still hasn’t gone to turbo, thank God!... because turbo engines are so pressure sensitive I think it would add to the complication of putting more fuel injectors so that’s why most turbo engines havnt gone dual port and direct except for Ford I believe , but they have no concept of spending lol. I have a new Camry best decision ever.
GDI systems have been in use for 20 years now on vehicles. The manufacturers have been aware of the valve coking issues in GDI's since the 1990's. The Dual injection system has been in use for over decade on some of German GDI systems. The Dual system is nothing new and it is pure negligence and or cost reasons it has not been used on Current GDI systems.
I can almost be sure, that at leat 95% of GDI engines out there have carbon deposit problems. Friend of mine, mechanic, he gets a lot of 2009-10-11-12etc etc cars with a complaint of lacking power and bad gas mileage. Many people are ready to sell them at that point, they just don't know they are ending up with another "new" GDI car, which may just gonna live until the manuf. warranty expires. I usually tell people to do their research before buying the car. GDI engine is not like "digital" or "supercharged", it is actually worse than multiport injection. These are throw-away in 5yr cars!
Scotty,I have for quite some time,been following the Oil Catch Can debate ( Do they work or not) In Australia,there is a company that tested 3 identical cars fitted with the Ford 1.6 litre Ecoboost engine.These cars were tested to 150,000 miles. One car was fitted with a very expensive catch can.The second car had very regular oil changes,more frequently than Ford's recommendation.The third car was stock,with services carried out to Ford's recommendation The results were as follows. The car that had more oil changes than it should have done,showed significantly less carbon build up on the valves,than the other two.The engineers,could see no difference between the car with the Catch Can fitted and the one that was stock. I think these real world tests,for me at least,proved that Catch Cans are basically, Snake Oil. Changing the oil regularly with good quality Synthetic oil,is the way to go. Has anyone in the US,carried out a similar test,if so can we see the results.
My 3.0L V6 on my 2007 Mercedes does not have direct injection and the piston rings are not worn but I installed this same model catch can anyway. The intake manifold has cheap plastic secondary flaps that are known to get coked up with carbon and impurities from the PCV which cause the secondaries to bind up and eventually break. It’s an expensive fix because you have to replace the entire intake manifold. Oil catch cans are a good idea and can only help not hurt as long as they’re installed correctly.

Scotty i want to change the muffler to make the car quieter
Can you talk about it
Scotty Kilmer what brand catch can is that if i turbo an engine i wanna use that one it looks like good quality
My car burns alot of oil.. Would using an oil catch can help?
What about the 2011 Cadillac CTS 3.0L V6 DOHC 24V engine? My car is with that engine.
Speaking of carbon build up, how do you feel about the hydrogen clean up trick? TIA.
I absolutely love the fact he gets the point in the first 6 seconds.
Other UA-camrs always give their speech about liking and subscribing at the beginning.
You're a genius Scotty!!
Was just thinking the same thing
If you need me to like and subscribe before I even get into the topic it's probably not worth watching.
He knows more
Wring
It's nice to see a mechanic that knows what he's talking about, is up to date & has a caring heart. Good job Scotty...
Exactly! Scotty been in a tare with very good imformative videos lately.
I HAVE A 2012 GMC TERRAIN.2.4..REALLY HELPED THE PCV SYSTEM...COLLECTS ALL THE OIL GUNK FROM GETTING IN MY INTAKE MANIFOLD..THANKS SCOTTY ..EXPERT ADVICE..
If you have a lot you could have a vacuum leak
Boy, he rarely misses an opportunity to remind us about the resilience of his 240K mile TOYOTA. 💰
Michael B. 🙄
Michael B. - I wouldn’t buy another DI Volkswagen if it was half price. I bought a Toyota particularly on Scotty’s recommendation. But ha I noticed that too
Well sure people laugh at a toyota for its vanilla flavour but they stayed away from Turbo and gdi, hence the proven old school reliability. Play it safe.
I bought a 2002 Chevy Malibu cause I wanted to support Detroit. Five years later, the car was having throttle issues ( revs up at stoplights ). Took it to the dealership. They couldn't reproduce the problem. Paid the 1 hour labor fee. Am I trusting this car to haul my wife and 2 year old around the mean urban streets of Los Angeles, at night? Abandoned domestic cars after that. Vanilla Toyota for my family!
LOL! EVERY one of our Ford vans and trucks made 300k all the time.
And we drive the piss out of them!
Plus we don't even change the oil every 3k but every 7,500 miles and very minimal other maintenance.
The myth that only Toyota's break 200k on an engine is so silly.
Those snobs don't even drive their vehicles as hard.
A caution on using oil catch cans in winter: they can freeze up and block the PCV line. The can is fine all year until you get freezing temperatures, then condensation starts to build up in the can. You actually get more water than oil in there in the winter months. It needs a lot of maintenance in a Canadian winter and becomes a hassle because you have to let the whole engine bay heat up hot before all the ice will melt so you can drain it. If ice builds up in the actual lines to the can you can get a blockage. Happened to me and blew my valve covers with the pressure. Happened again and blew my engine. I'm just leaving off the can in the winter now, not worth the hassle and risk.
Word of warning in cold conditions and can be an expensive repair. Well commented on !!
+428ghost - If you are " Catching " a lot of moisture... More likely you have a Coolant Blow-by / Head Gasket Leaks! NOTE: If anyone here have the same.... Try Bar's Leaks Head Gasket Sealer, before it get worse! I did that with my Dad's Car and Truck.... OMG.... Now I only catch oil. Before, I was getting like 1 Ounce of moisture every 100-200 Miles! I made a few Video on my Channel if you want to see that!
get an air oil separator that has built in engine heating to prevent freeze up. Best solution. usually just have to run it off the throttle body coolant hoses
Captain Howdy haha “sweating it” like the condensation that builds up. I have no friends.
Hmmm, a serious problem in cold parts. What about a tee close to the PCV valve with the middle of the Tee being kept closer to the engine and in a way that goes down the engine block then putting a clear container almost level with the sump but again where the engine keeps it warm? A tap under the container let’s you drain it away once there is enough to make it worthwhile.
Could be hard to find a spot where it’s not too hot not too cold.
Customers buying a car should not have to do makeshift things like this, the companies engineers are paid to do a job, why can’t they design a solution to this?
It annoys me greatly and worries me as well: if they cannot work out a solution to this then how good is the rest of the engine. Just like DPFs’ Diesel Particulate Filters - on the Toyota Landcruiser Prado in Australia with the 2.8 engine they have stuffed the design, why did they not look to the European vehicles and modify their solutions?
Anyway this is just a thought.
Good luck with this issue.
All this time later and your video is still helping. I installed two catch cans on my turbo engine. Great work! Love your videos.
why two?
@@jminkvihubyb one for each valve cover on a 2jzgte vvti. I needed to replace the valve seals. Too much blow by.
Scotty - you are like Huey Lewis in the 80s - you just keep putting out the hits. Great job. I learn so much from you.
Save me all KINDS of money!
He's takin' what they're givin' 'cause he's workin' for a living.
I want a new drug!
Too young to know what you're talking about 😂
Huey Lewis and the News
Scotty, I remember back in the day when most cars vented the crank case thru the tube down the side of the block to the ground under the car. This left a black tar stain on the road about a foot and a half wide that you stayed the heck away from if you were riding a motorcycle lol!!
I run an oil catch can on my 2011 Supercharged Wrangler. I empty the can about twice/year and it's TONS of gunk always in it. That's what we're keeping from going back into the intake, folks. THESE WORK! I'm installing one on my 2019 BMW 330i, as I just cleaned my intake (GDI engine) and my valves were CAKED UP BADLY! You need a catch can on a GDI engine.
I hope Scotty is making a living off these videos. Because if he stops uploading, i'll be stuck watching Bravo with my wife.
His socialblade says he is making a damn good living off these videos. lol
Scotty readily admits he is a UA-cam millionaire.
😂
Of all people on youtube...
He deserves it
I’d rather cut my own throat
The exact tech we've had on small recip aircraft engines for 70+ yrs. Works great and, I even have a secondary catch can installed after the air/oil separator to save the lost oil.
@BMO Yes, you could do that however, I just put that same Small amount of catch can oil back in the engine.
Isn't that a bad idea considering it is actually a (even if miniscule) oil water fuel mixture? That would lower the viscosity of your engine oil. @@daverossiter717
It is unconscionable that car manufacturers did not know this extreme level of intake valve carbon build-up would occur going into the game.
Volkswagen is utter shyte
Impalaman's Garage it’s about business make a short lived engine so we’re forced to buy a another car to keep money and production moving in an endless cycle.
They know it happens back in the past youd just have a hose going to the ground but your not allowed to do that now lol
As long as it meets EPA regulation and survives past warranty... it seems they don’t care.
Planned obsolence
Yes! You answered my request to put this video up! YOU ROCK SCOTTY!!
Hey Scotty, I purchased “M7 Racing” oil catch cans for both the turbo side and for the PCV side for my MCS r56. I notice the cans aren’t baffled with anything. Should I let it be hollowed the way it came or should I put stainless steel mesh inside or some type of material to help it filter better? Seems like no one really knows definitely what is safe and what isn’t out there on the internet. I would trust your judgement before anyone else. May you pls make a suggestion. Thanks again God Bless
Thanks, Scottie. Seems like the emissions control systems on GDI engines would be screwed with oil from the combustion products from oil blowby (and oil coming down the valve guides). Another problem with blowby is the blown oil seals on the crankshaft, which occurs when the PCV system gets completely clogged (due to poor design) and the blowby pressure has no where else to go. Case in point - the GM 2.4 L Ecotec engine, the engine design equivalent of the disaster known as the Chevy Vega. Thanks for this video and your opinions, and thanks for continuing to make them brief and to the point.
204,000 miles on my 3.6 DI in my 2009 CTS. Doesnt miss a beat. No catch can. Good oil will also help. Never used anything but Mobil 1.
I love how organized and tidy his shop is! OMG!!!
Hes got my money anyday..regardless
Looks like my garage. Just a walking trail thru the middle.
@@johnchandler1687 I keep it that way too, mostly so the wife and anyone else visiting doesn't come past EITHER garage door.... it is my island and I cannot be bothered while I'm there. Only downside is I have to stay nimble and limber in case I need to get anything
Bet he knows exactly where everything is though
The mess is almost always a sign of WORK being done there...
Scotty has the best mechanic channel on UA-cam, I have learned so much because of him!
Deathhound
And save a lot of doe!
UA-cam recommended me to watch this video today (Jan 29 2020).
If my facts are correct I recall Scotty covering in a previous video that newer Honda engines going from 2010's and upwards are Gas Injected Engines.
Again recalling Scotty's little news bits Honda is releasing a new synthetic oil sometime in 2020 to combat the carbon build-up on the pistons and the rods.
Let us see what unfolds as 2020 keeps rolling along.
Scotty absolutely love your vids. Learn so much about history of engines and problems that occur with engine design. Never realized how clean the valves stayed by injecting fuel directly into the intake valve system with direct injection. Hoping to soon modify a Buick 1963 215ci V-8 to direct injection with some Rover parts. Now I know exactly how I want to introduce the fuel to avoid problems.
You are GREAT!
I wish I had a dollar for every engineer that screwed up a design.
Eh...it comes with the territory. Aluminum block engines, cylinder deactivation, fuel injection computers...the early ones had problems. It doesn't mean they weren't good ideas, they just weren't tested properly before release.
Sometimes they screw up due to management. And possibly on purpose as well. Pinto, anyone?
Most of the time it's not their fault. Automakers task them with speed of assembly as a first and foremost goal, with the fewest human hands on the work as possible. Often times engineers will come up with a beautiful masterpiece of engineering but a marketing guy will hore a 'value engineer' (thats a real job, google it) who will take everything good out of the design to shave a few cents off production costs, or to use existing parts so that they can save from having to make new tooling, or simply the logistics of shipping inventorying or storing new parts, or simply removing as little as one production step.
GM is notorious for this. To this day they use the same delcotron alternators that have a fatal flaw of blowing up if the battery's ground happens to be loose, GM locks can be serviced by the same kit of parts all the way from 1934 through 1994 with the addition of just one single part. They have keys that are all dimensionally identical as far as keying specifications go starting with an "A" blank through a "K" blank when they switched to a double sided key in 1994. The manufacturing process in 94 used the same metal stamping tools from the 30's. The only change was changing the setup of the milling machine that makes the grooves in the side of the key to slightly different locations.
Even their ignition lock body castings were reused, In the 70s and earlier the locks slid into the steering coloum and snapped into place. Problem was they were easy to yank out with a slide hammer, so they stopped putting in a spring loaded retainer and instead machined a groove in the side to hold it in place with a bolt! Guess what, even though the spring loaded tab isn't there anymore nor the slot machined for it to go into, the spring is still present staked into the side of the lock body even though it had no function for over 30 years!
Funny enough The company that makes GM locks, strattec, formerly Briggs and Stratton also makes chrysler locks.
Inteterestingly enough the double sided gm keys from 94 on are a mirror image of the chrysler/dodge keys from 97 on except the chrysler keys are a tad thicker.
That seems coincidental but it's not.
When strattec's dies for making GM keys get worn out, they flip them around backwards, run a broach through them, and then they can make chrysler keys. All that so they can use a die that probably cost 5,000$ to make and can produce millions of keys, and do a small mod to it and flipping it backwards in a machine to produce millions more keys for another one of their customers!
The same goes for engines and more.
Often times this can cause problems down the road and or make things far harder to fix, but that is of no concern to people who make and sell cars, if it saves those people a single red cent they are going to do it!
Even a penny !
+Willy Automotive Yes, even a penny. Look at the ford focus, there are like 5 million of them out there and everyone who has ever worked on them knows ford and mazda cut a lot of corners to pinch pennies here and there on them. 5 million times 1 penny is 50 grand. If you save 100 pennies over the whole car, which is a great underestimate you save 5 megabucks. That's a lot of money that the company gets to keep as profit.
SCOTTY must be SMART GUY he bought same exact Catchcan as i have on my car.
it worked immediately from the start, on very first drive of only 8 km the filter was already wet with oil
I used to think I knew a lot about cars.
You’re amazing Scotty. Thank you
I have been running a catch can on my 3.7 mustang, between oil changes (every 5K) I collect at least five table spoons of oil. I've been running one for about two years and I have probably kept at least a half of quart of oil out of my intake.
My engine is not forced induction and I don't drive crazy. I do drive spiritedly from time to time but I don't abuse it.
I so much enjoy Scotties videos!! I would give almost anything to have a good mechanic and HONEST mechanic like him where I live !! He or she would make a killing
Thanks Scotty! You convinced me to order Catch Can (via your affiliate link) to my Hyundai Santa Fe with GDI engine, in the long run it's cheaper to install $35 catch can than use CRC intake valve cleaner $10 per can
Glad to hear it, thanks for the support!
My catch can cost 150$ :/
Be sure to replace the hoses that come with it (assuming you got the same one in scotty's video which I also have) with new more resiliant fuel line (Can get from autozone by the foot). Also get you some hose clamps, and your good to go!
Really like my catch can. Easy to install and maintain.
Wow i wished i would have known this when i bought my 2012 kia soul i bought the crc cleaner and will buy the catch can after i clean it
+TheMidnightNarwhal - The People who you bought from went to a nice dinner for sure!! 😂😂😂😂😂
On many older cars without a pcv system, we called the crankcase vent tube to the outside air a 'road draft tube' as that is what is was. They actually used physics back then. Not all older cars were so lucky.
Ever since I purchased my 2015 Ford Escape with 1.6L ecoboost, I looked for any advice to maintain my vehicle using UA-cam. Saw my first video of Scotty and absolutely enjoy his videos, and respect his knowledge of what I might need to keep my vehicle running. After watching a few videos regarding the engine installed on my vehicle, I've sometimes wished I purchased something different. After watching this video, I have since purchased the catch can as recommended by Scotty hoping that it will help with excessive carbon buildup on the valves. Anyone have a description of what lines to connect the catch can to? Look under the hood, and say to myself that it doesn't look as easy as I thought it would. Just want to make sure I'm accessing the correct lines so I don't cause myself more problems. If I know exactly what to connect it to, I am comfortable installing it. Thanks Scotty. From a happy subscriber.
Well Scotty, you have another excellent video that can help owners save thousands. This PVC Catch-can is a cheap, less than $50, prevention item that should be done by thousands of GDI owners a.s.a.p.! Make sure you get a decent pressure capable can with a heavy screen to keep the water/oil at bay, coming through the PVC system. I do like the can models that have a drain on the bottom with a drain valve. Great idea, great video. Keep Rollin'!
I had a 2000 Saab 9.5 Aero with the 2.3 liter engine that was equipped with a factory catch can.
Hi Scotty my wife has a PT Cruiser & later down the track I went & took the top off the air filter box & just to check the condition of the air filter & I was quite shocked the air filter was covered in oil & I took the whole complete air box out & cleaned it up & took awhile to clean all the oil out of it & then I thought of a solution & I cut the cut 2 of air breather hose & mounted 2 breather filters on each end of the breathers & I thought that would work & put in a new air filter back in the air box as it was nice & clean & having those breathers on the end of the 2 breathers was going to be ok but I was wrong & when I went with my son to take the PT Cruiser to a garage to get to new tyres fitted to the front to get a Warrant of fitness & noticed oil on the concrete floor from under the PT Cruiser & noticed the oil over the rocker cover & had come from the 2 breathers & I went oh no & I'm going to have to get a oil catch can the mechanic that was there I told who was Tony & that I will need to get a oil catch can & the one that Tony was going to get was too big & so I'm going to have get an oil catch can from AliExpress & the oil catch cans here in New Zealand range from $109.00 & $326.00 & up to $858.00 & that is by way too expensive & may have to try AliExpress Kind Regards Peter & other than that the engine runs fine & I know it's got blow by & I can't afford to do the engine up Scotty
Things I learned from this video:
Buy an old toyota
Never buy a volkswagon
Pretty much all of scottys videos teach you to buy a Toyota
Yeah, never buy a VW...my 18 year old Golf Mk IV has just clocked over 265,00kms. It runs like a German clock, apart from standard servicing and maintenance, all I've had to do is replace the fans. I gives me great fuel figures, and laps up my 1000km/week commute. Every manufacturer has good and bad models. Scotty obviously loves his Toyota, and I get the fact that it's reliable. But for people who actually want a car that handles and is fun to drive, a Corolla is just white goods on wheels. Different strokes for different folks...
i had an old Toyota... it died. Also my profile pic is my friend's 92' Camry that blew up. I don't think they are bad, just like anything, they still break. but i do agree with not buying a Volkswagen
japanese cars have good engines and horrible interiors.german cars have good engines and nice interiors and good handling but not so cheap to maintain.once you drive a german car you wont like to drive anything else.
I've driven and worked on many German cars (VW Jettas, golfs, BMW 3series, older 7 series, Audi A4, Mercedes Sprinter maybe others) they all had a nice ride (except the sprinter and bmw 3 that the rear subframe broke) and decent interior but i liked my interior on my older Cadillac much better and VW interiors seem to always smell like crayons and have the weirdest cup holders for no reason and always break. 1990's Passat cup holder is the worst i've ever seen for design. Also the 20v 1.8T engine is terrible. The main reason i don't like German cars is because they are so hard to fix, it's like they make it hard to work on on purpose
Straight to the point simple to understand for everyone.
I have a GMC Sierra 2015 which is GDI and I don't know if General Motor have thougth about this problem at this time but when I bought it in 2018 I didn't take a chance and already installed one. It surprisingly how much sludge it can catch in little time.
Actually find this video to be extremely helpful, my vehicle have had a string of carbon build-up related issues recently, hopefully it will be helpful in limiting future problems at least slowing the progression.
Thinking about putting one on my festiva. Was looking at the intake when I had it off and it was covered in oil spray.
I have this exact one on my Silverado and it works awesome!!!

Hi I’m from planet 🌏 lol 😂
Hello from URanus.
That's a good idea Scotty! I think I'll purchase one for the 85 Ford F150. it has blow by where the rings are worn. I think that would be a good idea.
We just run a rubber hose pointing down on it like the diesel engines have, but think that might be a better idea 💡.
Thank You Scotty! I appreciated everything you do on this channel.
Thanks Scotty! I just got catch can in wife's chevy cruze 1.4l, but after watching this I feel like I need to get one in my 2015 silverado 5.3l too
Scotty, what in your experience is better for a diesel engine: Oil Catch Can or Bypass oil filter? Best Regards
Brah I use the blow by catch can filter its total tits!
What about the old system used that vented the crankcase vapors into the air cleaner housing? This worked pretty well due to the larger surface area of the pleated-paper air filters. The air cleaners would normally be changed regularly anyway, so this seems like an acceptable solution that would work well now with DI engines.
I have a 2016 Audi A5 (2.0T) w/GDI. I installed a catch can when it was basically brand new. Initially, it did capture a little oil. Perhaps it was due to engine break-in? After a few hundred miles, the catch can never has any oil in it anymore. It's just dirty with a dry residue. Is this normal? The engine currently has 17,700 miles on it.
Mr Kilmer, I wanted to thank you for this older post. I found it to be one of the most informative automotive post I've ever seen. I hope you're enjoying your well-deserved retirement sir.
Which one was it ?
Wow! I just learned something new, Thank you Scotty
I dont call myself an expert by any means but I do own a 2018 direct Injection car so I will speak from experienced. I've been doing my own work on my own vehicles since I was young and have been tuning cars ECU for the past 8 years. Catch can alone doesn't get rid or slow down carbon build up especially with engines running with egr and tgv systems. When I checked my intake valves at 22k miles with catch can installed at 1k mile, it had tons of carbon build up on it so I had to do a tedious job of walnut blasting the carbon off. I installed an Air/Oil Separator, did a tgv deletion and an EGR deletion to slow down the process of the carbon build up and retuned my car's ECU to run properly. You will never totally get rid of carbon build up from a GDI OR DI motors but you can slow down the carbon build up by doing those things mentioned above.
I just purchased one for my 2014 Ford Focus 2.0 thanks for the heads up I got the exact one you were showing
glad to hear it, thanks!
3:07 that’s what she said
Should I install one in a 2018 Chevy equinox gasoline engine and / or 2020 Chevy trax
Toyota's D4-S direct and port fuel injection is the best of both worlds, power and fuel economy of direct injection, clean intake valves and low particulate emissions of port injection.
To me it looks like double the number of injectors to break and/or get clogged up, plus the extra associated wiring. I can't argue about the improved fuel economy and performance though....
driftbro yea big deal Ford Motor did it earlier with Gen2 Ecoboost.
David Klimmek ignorant fanboy detected
driftbro yea dont like factoids that prove you wrong eh? Toyota didn't pioneer anything.
@@Davido50 yeah....sho yo right! Toyota didnt pioneer anything, except undeniably reliable, headache-free, safe, and did I mention....Reliable cars!!
This is a great and perfectly explained advice video. I wish all youtube publishers went straight to the point like Scotty here. I nominate Scotty for an Oscar.
My 2013 Hyundai veloster turbo just brought one will be installing soon
I just want to know if I install this will it void my warranty?
2016 Mustang GT put on an JLT oil catch-can , works great my engine thanks me each oil change....
Just ordered the jlt for my 3.5 ecoboost. Kind if pricey at 173$
Can I put one for my 2018 Honda Accord sport you think is good will help my car
Hey Scotty, I hope you can find the time to answer this question for me. I have an MK6 Golf R that I have been considering getting an oil catch can kit for. All the full kits come with a block off plate/ adapter for the original pcv and warn of possible freezing in cold weather. They advise cleaning once a week when cold and to completely remove it and install the original pcv when temps are below freezing or you could potentially damage the seals in your engine. Is this a real concern? What are your thoughts on this? Thanks.
Threw one on my chargers 5.7. Can’t believe how much oil gets into the can.
I used 1/3 a quart on a 1700 mile road trip with a 5.7 Grand Cherokee. I changed the oil with Royal Purple full synthetic right before the trip too.
I hear that all the time about the Hemi motor. But they aren't GDI, so does it really matter?
It does, mileage will drop and carbon deposit reoccurs via fuel. When oil is burned it increases chamber heat for an even burn of the fuel. If that oil not present the fuel doesn’t burn clean and you are where you started.
Jack Torse You know probably increases HP only mildly, I know with my race Kart and probably other race cars they have them, just so your not burning the oil as it is more of a dampener on the combustion process. Really these are here like Scotty says for emmisions.
My theory. When in doubt Rev it Out.
Hang in there Scotty. Mint advice, as always. Keep your neighbourhood safe & stay happy.
The irony of this whole GDI / Gunked up inlet valves scenario is that we go to the effort of filtering and cleaning the incoming air for the engine; so if it was just a straight intake to turbo to inlet manifold, the air would be perfectly clean (relatively speaking) and there would be no gunking up of the inlet valves at all. But we (automotive engineers, that is) decided to recirculate all the gunk from the cylinder head back into the engine intake again *POST* air filtration, without considering that it might need to be filtered or cleaned first, and may cause issues down the line!! Very big fail.
So, you are proposing to have the PCV to dump somewhere outside of the air filter? And let the engine’s air suction draw the air through the air filter? Well, I think the oil from the blow-by will permeate through the air filter. And it will get on the MAF sensor and foul it. And still get into the engine intake. I suppose maybe if the air filter was redesigned to handle the increased amount of ail it would see.
Catch cans are actually a really good idea especially for forced induction and high horsepower cars
is the newer generation 991/992 Porsche 911 one of these cars? I heard the infection sprays over the intake valve on these.. yes?
Hi Scotty, does that mean that if you have an old clunker that consumes oil, instead of having to change the catalytic converter every time you pass the state inspection, you can actually put a catch-can and make it last longer?
Thanks Scotty! You've been right so far in every video and I look forward to seeing more of them.
Thanks again for making them!
The 2.4L Equinox has been designed to prevent a catch can installation. In fact, it's been designed to prevent service of the PCV system all together. They even designed in a trap on the makeup air side so if your vacuum side becomes clogged, the water vapor will freeze in the makeup side and destroy the engine. Genius right there.
😂
I was tempted to get a ford flex recently, but hesitated because of the GDI engine. So I got a lexus instead.
Adam McGrath poor decision! U bought foreign plus a less sophisticated motor. Ford & Lincolns GDI turbos use dual type injection no carbon on Gen2 ..really was no carbon on Gen1 Ecoboost. Buy American!
David Klimmek Nah; something else on that Ford would have been more likely to go. Used Lexus is similarly-priced and better quality than new Ford.
But Ford is not as reliable as Toyota
Davin Peterson 280k on my Ford ecoboost,it’s pretty reliable.comes down to operator maintenance
Although operator maintenance and oil and filter choices can account for 30-70% of an individual vehicles life span, the quality of the oil pump, the quality of the valve seats, piston ring design, etc makes a bigger difference. Although Ford does an above average job with their trucks there is a real reason they anounced they will stop making most of their cars and that is not due to operator neglect. Consumer Reports annual car guide based on 500,000 to 600,000 reader surveys doesn't lie. I've been looking at it since 1987 when I got burned on a Chevy while in college. I encourage everyone to look at the guide. Pass on what the writers write as all humans including myself have biases.
Pretty much if u have a Kia or Hyundai you need a catch can. I have a genesis sedan v8 though it is not a gdi I still have to get a catch can because carbon build up on these v8s
Its also worth mentioning that if you drive a turbo car your intercooler will turn into a catch, so a good idea to have a catch can even if you don’t have direct injection.
Hey Scotty, I’m getting older and use a penile catch can every night to keep from getting up every hour to use the restroom.
@aspect ~ Now THAT'S recycling ! ;-)
Puddin on the ritz
It comes with a built-in dip stick to tell you when it's full.
Hi! Does anyone know if these can be used on Diesel engines??
Hi Scotty, A question:
I am at least as old as you are and yes I do remember the old cars with the down draft pipe to dump the crankcase pressure directly out into the atmosphere and the small amount of smoke they emitted.. Which makes me wonder if we would or could just bypass it entirely now also and dump the pressure overboard (as was done in the past) and eliminate any need for a catch can on direct injection engines and eliminate the need to remember to empty the catch can. Sometimes like you I believe the simplest solution is often the best solution. Like you I also miss roll-up windows and vent windows on our side windows, manual transmissions and the old fresh air vents down near the floor on the drivers and passengers sides of our vehicles.
Scotty... How much STOCK Has Toyota Given You For Proclaiming Them Better Than ANY OTHER car manufacturer
Love this guy. But wish he would talk a bit more about diesel cars... You see I'm from Portugal and all we have here are compact diesel engines...and I think they suffer from the same issue mentioned in this video and even worse being all the diesel cars turbocharged.
Still I enjoy watching your videos Scotty even though I don´t have a petrol car :D
I agree, most cars sold in Europe are diesel. From BMW, Mercedes and even Hondas...
Alex Arriscado
Vws tdi likes to clog the intake with goo.
Either get a retune to delete the egr or do an intake cleaning every so often.
I did it on my 98 Jetta by removing the intake and cam, and using a propane torch to burn the stuff out of the intake manifold and intake ports.
Then since I was cheap, I made an egr block off gasket and lived with the check engine light being on, I didn’t want to retune.
Occasionally I’d do a scan to make sure the light was on because of the egr and not more codes.
I cleaned mine at 130k, and I could barely get my thumb down the main intake hole.
Alex Arriscado Os Diesel usam a EGR, o efeito é o mesmo.
Frank. T Thats from Spain :D
Alex Arriscado Ask him when he goes live.
Ford Eco-boost prime example of why you need one.
I have a 2013 Lincoln MKS Eco-boost AWD sedan one of the 1st things I put on when I bought the car.
Ol,Scotty love the videos brother, Greetings from Glenwood!
This is well-known on my platform, the Mazdaspeed 3/6 (turbocharged, direct-injected engine). One of the keys is this: if you put this on an engine that has 20-30k miles on it already, you're still going to need to pull the intake manifold and walnut blast the intake valves because accumulation has already occurred to really start off with clean valves. If starting with recently cleaned valves or a new engine, this will definitely help mitigate accumulation, but not stop it entirely due to EGR systems also putting oily air over the valves as well, in many engines. If you really want to address this, installing a water-methanol injection system will not only steam-clean the combustion chambers, it'll also keep the intake valves very clean. Additionally, it lowers cylinder temps, raises functional octane (M1 methanol is 116), and allow more boost and timing to be run if you're going for performance tuning on your setup. Finally, the evaporative cooling effect of methanol significantly lowers the air temperature entering the engine, thus increasing oxygen density and facilitating even greater power production.
You seem pretty knowledgeable with engine mechanics so any thoughts on Honda's current 3.5v6 in Odyssey regarding carbon buildup? Do you know if Honda has addressed the DI problem like Toyota or Ford? Thanks
What is this you speak of?
Methanol was found to cause excessive wear in engine parts, that's why ethanol is used instead
does this depend on the dilution of the methanol?
@@tjsullivan4793 Not sure about the Honda engine, sorry. Most folks have taken a hybrid injection approach, utilizing both PI and DI, which completely addresses the issue. You see this in the FR-S/BR-Z engine, for instance. Sorry, wish I new more about that engine.
just bought a 2018 ford f-150 with the 3.5L ecoboost twin turbo and just ordered the oil catch can too.
Hi Scotty I love your videos and learned a lot from.
I got a new 2021 Explorer with the 3.0 v6 twin turbo engine. I wonder if that engine needs a catch can ?
Thank you for your help. And be awesome as always !!!
Do I need an oil casting on my 2010 Chevrolet Camaro LT ? or a 2012 Nissan Maxima ?
Strongly recommend this for any turbo subaru

Hello from Perth, Western Australia!
hello again!
Ditto, same to you
Car Guy same, Bayswater
Melbourne here 🖐🖐
Hello from Wentzville Missouri USA
Scott, Following your advice, I'm shopping for an oil catch can for my 2012 duramax equipped Silverado 3500HD, and my 2022 Mitsubishi Outlander ES. Both are direct injection, the Outlander is normally aspirated. Any thoughts on what to install? Also, temps in my area can go to -40.
I got a 2011 mazdaspeed 3 and regret not doing this when I bought it
What is a mazdaspeed3 ?????
Ab Abner Mazda 3 MPS in some countries
Why do you regret not putting one on, still have the car? Just curious.
Is this needed on other Mazdas? I have a 2011 6 v6 I don't think my engine is a GDI...
Just to let you know Scotty, the reason they didn't put them on at factory and didn't notice the problem is because valve on gunk will not show up in a 500k mile torture test where its continuously running. What builds the gunk up is the constant idle, accel, decel function with the warming up cycle and cool down cycle over thousands of miles that creates what has been a problem on some of the DI motors in the VWs, Audis, Bmws, and the slightly older Ford Ecoboost motors until they also did the Dual injection system with port injection and DI. So anyways the reason they didn't realize to put on a catch can system from the get go is because when they have their cars in the testing facilities running for 200 hours straight it doesnt give the environment that will create the build up of carbon.
Seems logical - making cars less polluting has led to making them break down. This takes them off the road. Sooo logical. And then you buy another. Which then clogs up just like the last. This is the first video I've seen about blow by which shows the catch can itself. Very simple. Diesel tuners recommend them?
Scotty I’m local to you ball park figure how much would you charge to install one on a 2017 Focus St.
This device is for people who maintain there cars properly. I like that line 👍
Ya my cummins 2003 24 valve crank case vent it just a tiny filter with a tube going down to the floor. Its awsome!
I put a jlt catch can on my mustang, works great, trans am is next to get one
One of the first things I did was to add a JLT to my 2015 GT. It's amazing how much oil it cathces.
Have you noticed that your oil level drops between OCI ?
BMW could benefit from this. I’m sure it’ll reduce your chances of needing to walnut blast the intake.
Scotty is a national treasure, protect this man at all costs.
@LucasMaclean-fy7st real sarcastic XD
So if my car is gasoline indirect inyected this is not necessary, right?
Reminds me of having to grind the valves on car of the leaded fuel vintage.

I bought a 2019 Mazda CX5 non turbo for my wife a few months ago and started thinking along the lines of a oil catch can. I did some inspecting first. I pulled the three hoses that connect to the throttle body and ran a Q-tip inside each hose and didn't find any oil residue at all inside these tubes. The car has almost 4 thousand miles on it so I suspect there would be oil residue inside one of the tubes. Looks like Mazda did their own research about this problem while designing the SkyActiv engine.
3:07, "that's what she said"
Then the bed broke
Joe Rumler you went from 1st to 4th gear
Who knew Dennis Hopper was so knowledgeable about cars?
And he does it with such Speed.
Another reason to love my 2014 Toyota. No GDI, no Turbo, no problems
get those BS garden hoses off the cans and replace with fuel hose or better....also alot of manufacturers are NOT using the dual system that Toyota/Lexus is using....most dealers won't know...so used car buying requires alot of research beforehand even if it is a 2015-16 car.
David Santiago yep. New honda accord for example is gdi only
Toyota still hasn’t gone to turbo, thank God!... because turbo engines are so pressure sensitive I think it would add to the complication of putting more fuel injectors so that’s why most turbo engines havnt gone dual port and direct except for Ford I believe , but they have no concept of spending lol. I have a new Camry best decision ever.
GDI systems have been in use for 20 years now on vehicles. The manufacturers have been aware of the valve coking issues in GDI's since the 1990's. The Dual injection system has been in use for over decade on some of German GDI systems. The Dual system is nothing new and it is pure negligence and or cost reasons it has not been used on Current GDI systems.
O P Volkswagen's 2.0 engine is direct injection and turbo. So are the GM ecotecs with turbos
I can almost be sure, that at leat 95% of GDI engines out there have carbon deposit problems. Friend of mine, mechanic, he gets a lot of 2009-10-11-12etc etc cars with a complaint of lacking power and bad gas mileage. Many people are ready to sell them at that point, they just don't know they are ending up with another "new" GDI car, which may just gonna live until the manuf. warranty expires.
I usually tell people to do their research before buying the car. GDI engine is not like "digital" or "supercharged", it is actually worse than multiport injection. These are throw-away in 5yr cars!
Scotty,I have for quite some time,been following the Oil Catch Can debate ( Do they work or not) In Australia,there is a company that tested 3 identical cars fitted with the Ford 1.6 litre Ecoboost engine.These cars were tested to 150,000 miles. One car was fitted with a very expensive catch can.The second car had very regular oil changes,more frequently than Ford's recommendation.The third car was stock,with services carried out to Ford's recommendation
The results were as follows. The car that had more oil changes than it should have done,showed significantly less carbon build up on the valves,than the other two.The engineers,could see no difference between the car with the Catch Can fitted and the one that was stock.
I think these real world tests,for me at least,proved that Catch Cans are basically, Snake Oil. Changing the oil regularly with good quality Synthetic oil,is the way to go.
Has anyone in the US,carried out a similar test,if so can we see the results.
Brian Smith Thanks Brian.
My 3.0L V6 on my 2007 Mercedes does not have direct injection and the piston rings are not worn but I installed this same model catch can anyway. The intake manifold has cheap plastic secondary flaps that are known to get coked up with carbon and impurities from the PCV which cause the secondaries to bind up and eventually break. It’s an expensive fix because you have to replace the entire intake manifold. Oil catch cans are a good idea and can only help not hurt as long as they’re installed correctly.
