Common Timing Chain Issues with GM Ecotec Engines | Timing Chain Rattles and Codes timing chain

Hey Good People,
I got some good information for your learning about the common issues on the GM Eco Tech engines. They are notorious for timing chain failure.
In this video, I show you how to inspect and prevent catastrophic engine failure due to timing chain issues. These engines are interference engines, a d if they jump timing, they will bend valves.
I hope you learn something from this video. Enjoy and thanks for watching.
Your favorite Mechanic,
Alex

I was reading about this. Apparently, the newer engines are Direct Injection engines. When the engine is cold, and you run it for only short periods of time (less than 30 minutes) excess fuel is injected into the engine so it can run. That excess fuel does not always fully burn with the less time to combust. It leaves carbon which mixed into the oil. Lots of short trips in cold weather, more carbon. More carbon, the timing chain gets stretched as the distance between the pins on the chain is extended. Over 100,000 miles, that is a lot of stretching. Advice - mix in trips longer than 30 minutes every week. Also, oil you use should be API-SP certified or ILSC GF-6 oil as it can contain the carbon better (not perfectly, but enough to potentially reduce the timing chain stretch). I am hoping doing these things will allow my Buick Envison with a 2.0L Ecotec make it to at least 150,000 miles. However, I appreciate the tip to change the chain at 100,000 miles. I will do that as well.

[@AlexTheCarDoctor]

Good advice as well buddy that may help a few people whoever comes across this thanks

All direct injection = Junk engine.

Got 222,000 on my 2.4 in my 09 Pontiac G6. I Change oil every 5k with regular conventional. No issues. Amazing engine

[@mrmarcink1300]

There is no more "conventional" oil unless you mean not labeled synthetic? Any brand name oil that is API GF-6 or GF-6b has synthetic esters as additives which would make them "semi-synthetic" this would explain at least some of the longevity, the rest is the 5k intervals.

[@alfredhowe8217]

Dropped off my 2014 Equinox at the dealership for check engine light issues, they found that the timing chain was starting to make noise. It’s got 108,000 miles on the odometer has had oil changes with correct Dexos certified oil at 5,000 mile intervals. We had no oil consumption issues until it reached 100,000 miles,now we use about a quart of oil ever thousand miles. Since we plan to keep the car we’re having it repaired.

Thanks buddy, I’m glad my video was Able to help you out man

[@denniswhitman6527]

I have used Heli-Coil kits onto many vehicle parts including body, engine mounts and internal engine parts as well. I have even used Heli-Coils on the Cadilac 4100 engine which was popular in the 1980's. Since the block was aluminum, I used double 1/2" inserts on the main bearing journals. I never had one of them come back for that problem again. I did work on other issues with the same cars over the following several years. So I can safely say that the Heli-Coils work well providing you install them correctly.

[@jimsix9929]

Alex had some great advice on the ecotech engine, as a semi retired mechanic with lots of experience( I just cant give up my shop) the best advice I can give is do not wait until it stops running, a timing chain replacement is under 1,000, can be done in 2 or 3 days not the end of the world but bent valves could total your car

[@AlexTheCarDoctor]

Thanks so much for your advice! I’m always open to learn! Definitely gonna use your experience and wisdom. Thanks again 👨🏽‍🔧

[@raypalermo1603]

At how many miles should they be changed?.

[@jimsix9929]

Ray it really depends on the oil, a car that gets a fast lube job every 7,000 could need a chain at 80K, if it is a neglected engine, like going over miles or cheap oil they can fail at 50K, use good synthetic 5w30 every 5K and it will last 200K, yes I said 5w30, the thin 5w20 is for fuel economy, not good for the engine, gas is cheaper than timing chains@@raypalermo1603

[@BellaRocko]

Lots of great information here. I didn't know some timing chain driven cars were so problematic. I wonder why Chevy went with the chain and not a belt on those cars. Thanks for sharing!

[@AlexTheCarDoctor]

I was wondering the same thing! I actually got one in the shop now, with a broken timing chain that I’m going to do a video on soon. Stay tuned! And thanks for watching and interacting in the comments 🤗

[@BDauto86]

Unfortunately belts have pros and cons as well. They're more likely to stretch, teeth round off, or break then a chain is. Generally the problem isn't the chain itself it's usually the guides or the hydraulic tensioners. Low oil or lack of oil changes will cause these issues prematurely as well. I also see and deal with alot of ecotecs, most of the time I fix them unless too much damage has been done.

[@atx-cvpi_99]

Because GM had major issues with the timing belt engines. They failed before the interval for replacement.

[@Maria-hm4gc]

I think Gm should replace it this for free since it’s a big problem with those cars, I have a GMC Terrain, 90 thousand miles and already have to replace a timing Chain it cost me $1400, that’s sucks …

Hey ive got a 16 equinox 2.4 auto awd. Its showing 3 codes i think, p219a, p0420, p0014, p0013 which is mostly timing stuff, fuel air mix, exhaust. it runs great one trip next time splutters everywere with lose of power until get plugs burning hot or something. Ive definatly gotta get a new hose that goes to use to be a pcv on Valve cover. But can you tell me what i need to do the timing completeley. lifetime warranty parts i dont like when their cheap because it means ill still have to do it again. If you have time id like to know what to buy and a fair brand something to actually last. Also my engine had the tube stopped offf on engine so lots seals and gaskets leak. What seals and gaskets that wont come in a kit can i replace while tearing into that part of the engine and any other things you would suggest changing instead of what i said? Any seals i can get to def needs done. it has abt 200000. people complains abt the 2.4 but ive not had to do anything until now with a lil over 200. ours has been great and we live in the WV mountians so its been used well. I hope you can find the time, Thanks !!!

hey Alex, do not be afraid of thread inserts, the repair makes the part stronger than a new part, the best ones are from Howmet aerospace ( an Australian company), napa auto parts has them, helicoil is ok too, no big deal to install and nothing to worry about

Had a customer come in for an A/C top off today. Needed a VC gasket and I thought I heard some rattle so I sold him a tune up and V/C gasket. (Almost to the 97500mi spark plug interval and I was already gonna be in there) I pulled the V/C and there was about a centimeter and a half of clearance between the chain and the top guide.

My problem is that her bank 2 camshaft sensor was bad and broke out the block and was pouring oil, i replaced the sensor but now the car only starts when that sensor is disconnected. When connected tge check engine light comes on but has no code, do you know whats causing this and if so how can i fix it? I did some research and have an idea but i want to know from a real expert of what it may b. Thanks for all that u do to help us all.

[@DevJB]

There is an upgraded 10mm hex bung cover bolt for the top guide hole, so you don't have to tap the hole at all. There is 3 upgrades to the primary tensioner. Cloyes timing chain guide in the front is responsible for breaking. The bolt hole tolerance is too thin. The guide rattles and breaks, especially in cold below zero weather while not properly warming the engine. Bad oil maintenance can contribute to it breaking faster but I've seen the front guide break multiple times in very well maintained 2.4 LE5's. Cloyes could upgrade the guide, there is enough room to expand the thickness of the top bolt hole, they could use better plastic, they could beef up the guide but they have not. I have emailed Cloyes with evidence and specs but they won't respond with any help whatsoever. Mellings can have my business.

[@dosgos]

Any special recommendations for parts preventative maintenance on a low mileage 2.4 LUK from 2013 that don't require a full timing chain job? Are there recommended upgraded parts or third-party parts for the full timing chain job?

I have a 2014 Chevy equinox. The timing chain guide on top broke and my timing chain ate a hole in my valve cover. Long story short replaced everything except the sprockets in a timing chain replacement and now I have a loud timing chain rattle on a cold start with rough idle after about 20-30 minutes of driving. If I pop it in to neutral it idles a little better but it idles much better if I just touch the gas a little. Any ideas? Edit: forgot to mention that if I let it continue to idle roughly it throws the code p228d which is a high fuel pressure regulator reading high fuel pressure it then goes in to limp mode and the stabilitrack turns off. It’s the only code that appears and I’ve replaced the fuel pressure regulator but with no difference in symptoms. The code will go away after a few starts and the check engine light disappears. I pulled the valve cover off and the timing chain is taught. I changed the vvt solenoids as well. I’m at a loss and I’m running out of money to throw at it!

Hello Bondo - read your comment. Sounds interesting. I have a turbo 2.0l ecotec solstice gxp and getting code p0016 for intake timing issue. Car with only 70,000 miles. One min car engine ok next on restart 5 min later engine running poor. Replace solinoids and sensors still with problem. Pulled off cover and chain is drooping between cam sprockets. U think could be just tensioner issue. Looks like on this engine tensioner is on left side. Could this tensioner be issue and could just unbolt current tensioner stud/spring unit and put in new one to take up slack? So then dont need to remove cylinder head and put in new chain?

[@AlexTheCarDoctor]

Hey there yes I recommend the water pump.I use the Cloyes brand timing kit

[@notme8121]

I strongly think that using a tread insert would fix and resolve the problem because once fixed the hole diameter in the aluminum is larger and stronger than when it was made. I kinda feel that all threaded holes in aluminum should have steel inserts from the factory since they would be stronger and reduce the seizing that steel bolts do in aluminum. of course I dont expect the factory to add all that work and expense just to save us trouble. so, are those motors pretty good other than that issue ?

[@DevJB]

Which engine code, -LCV? Just making sure, lol. If it's LCV 2.5 ecotec, yes you will want to remove the fragile plastic (insulated) intake manifold and throttle body while doing head gasket. (also clean them.) There is 5 bolts at the intake manifold gasket *replace gasket*. There is a lower bolt and 2 others, 1 or 2 hoses and a connector plug if I recall correctly. If you don't have a manual, research online first. Look at pictures of the intake manifold box so you know where the bolts are located before you begin. etc. ; ) If you do take the head off with the intake manifold attached. There is 95% chance the intake will break when you work on the head or move it around shop.

It does have the 5 bolts on top and one underneath. I was wondering if I could pull it out with the head and remove it after.

[@DevJB]

Usually it's the Intake phaser that goes bad, for top side. Or the hydraulic lash adjusters HLA's, Cam sensors or VVT solenoids. Front side is usually front cloyes guide broken and leaking throttle body or bad TB connector or rotting ECM. Back side is usually the primary tensioner failed. Bottom side doesn't have many issues except for the oil pickup tube will get restricted if a guide has broken; the engine will need yanked and taken apart for cleaning or the oil system will be faulty and possibly cause chain slack soon after repair because restriction or pressure blockage for hydraulic tensioners and HLA's to work properly. With restriction or bad oil, the chain gets slack and the front guide will rattle worse, which will cause it to fail much faster than it normally rattles.

Alex I have a 2015 Chevy Malibu I replace the mass airflow sensor, O2 sensor, the foot pedal the throttlebody. So when I’m driving, it still has the stable track light come on. and the auto stop doesn’t come on no more.

Hey there buddy that can be a number of things let’s start with the code it’s throwing that will point us in the right direction

The bad thing is it only has 93,000 miles

I had a 2008 Malibu I recently traded in, it had over 200 thousand miles , I never had a problem with the timing chain before I traded it in

[@A2J_Tim]

I did a repair on a grand am where that bolt walked out, I put it back in and about a year later we did the timing chain assembly and that bolt stayed in. The threads are not damaged, the bolt just vibrated out from factory torq being to low, thats my guess. If I were you I would repair that engine for your customer. Helicoil is a great product, I have used them for years, dont be afraid of thread repair.

I have that same problem right now that I'm working on what you did to fix the loose valves

[@AlexTheCarDoctor]

Hey there you have to take it to a Machine shop to have the heads redone that’s the proper way, if you have the skills and the tools you can just simply change out the valves and the valve seals yourself

I'm glad to have run across this video. I just got my car back from the dealership with this exact issue. I have a 2015 Chevy Equinox LT 2.4L. I had it towed back home today because they said it would take them 10 hrs to do the job and it would cost me $2100+ for them to fix it. I'm thinking maybe I should get another car. Or would it be better to fix it?

[@AlexTheCarDoctor]

Dang sorry to hear that. That is a common issue on the Equinoxes. It really depends on the mileage and the condition of the car. If it’s in great condition and reasonably low miles, I say keep it. If you get another car, you may be inheriting new problems with that one as well.

[@atx-cvpi_99]

Just get rid of it and buy a Toyota. These engines are junk. If it was burning excessive amounts of oil prior to the failure, it may need a new engine which is $3000 for a used engine and $4500 for a reman and that’s just the engine alone.

[@danielc8037]

Hi Alex I am in that situation like the last car you show. The car made a big rattle noise before shut down then try to started and did not. Finally I pull the engine out but how do I know if valves are damage ? Or is a fact if time chain is loose then the valves were damaged. I am trying to conclude if need engine swap or new time chain to current but don’t know how to check valves are damaged or not?

[@AlexTheCarDoctor]

Hey there buddy One quick way is to remove the valve cover And if the rockers are falling out like I mentioned in the video you have bent valve’s

[@danielc8037]

@@AlexTheCarDoctor ​ I did that after watching your video and they solid and well seated, no movement or wiggly. Today I removed the time chain cover I found a large black guide broken in 3 pieces, I turn the engine and try to align the marks on the chain and they are off by 3 links forward. Is that enough to damage the valves? or just new guides will be enough? Also a big click when turning the engine from harmonic balancer, after lube from piston 1 turn complete, I am assuming this noise is normal right? Thanks Doc. Daniel C.

[@AlexTheCarDoctor]

@@danielc8037 You may be all right but you will never know until you do a cylinder leak test that’s the proper way to test it out if the valves are leaking in any kind of way without taking anything apart or you can just put the timing chain on aligned everything properly and cross your fingers. it will make noise when turning it because of broken components if no components are broken it’s not normal for it to make any noise

[@danielc8037]

@@AlexTheCarDoctor Alex, Just want to thank you I did the engine swap and went smooth, I put 2000 miles already in the swapped engine, it was worth. I removed the time components from old engine because of the sound that I describe to you and put it in the swapped engine. As I mention is working great just one engine code with the Evap System from the car being sitting 6 month on the driveway, change the evac valve from the canister, I notice stayed always open t all times, and fixed. I got nervous that it was a misfired or something like that. It feels so good recover the car from junkyard that you think it was lost, I am taking better care of the swapped engine. oil change filters, etc. The interiors are great shape, ac, trans, etc. It gave me a lot of confidence on cars. Thanks so much for your knowledge sharing. Have a great Christmas

HELP DOCTOR! I have a 2002 Sunfire 2.2L. NO COMPRESSION ON ALL 4 CYLINDERS! Timing chain has a little slack, but not as much as the last one in this video. Some roller rockers are loose, but not all. Will bad timing cause ZERO compression? Thanks Doc.

[@AlexTheCarDoctor]

Hey there buddy yes bad timing will cause low compression on all cylinders. If you have loose rockers you potentially have engine damage, valve to piston contact has occurred.

[@markwilliams3940]

@@AlexTheCarDoctor Thanks Doc, but will bad timing cause ZERO compression on all 4 cyl's? Also, many of the rocker-rollers just fell off (when touched) where they span the spring and rod. Is this still an indication of "Catostrophic damage"? Appreciate the quick response brother. Last question. Thanks from the Kansas City Shade Tree Mechanics!

Great video what a young man these engines are garbage my friend has equinox with 98,000 miles has p0301 other mechanic said rebuild the motor so he took it to the machine shop and done it still has the same noise ticking at idle and exhaust popping and check engine light on and flashing even after the machine shop did it

[@dannyc8617]

Hey man, thanks for the insight, I have a gen 1 2.2 in an 05 Cobalt, I replaced the tensioner with the latest part from delco. The engine runs great, but still noisey on a cold start. Do you think a tension guide could destroy the motor? The chain is tight, had the rocker covet off when I did the install. I am not going to do anything else to the timing set as it is just a winter beater, just a curiosity question for my knowledge, and piece of mind.

[@AlexTheCarDoctor]

Hey buddy thanks for watching.it may be a tensioner like you said, it’s always important to change everything together but since it’s not an every day car it should be fine

[@archangel3237]

Noisy on a cold start is usually a vct actuator on the cam sprocket

[@dannyc8617]

@@archangel3237 Thank you for the insight, however this engine doesn't have variable valve timing, but the later versions do. It's been a while that it has been going on, but still runs very well, so I will just let it be until something happens.

[@DevJB]

@@dannyc8617 Some rattle for about 4 seconds or less is ok, while it is building oil pressure through all of the tiny galleys to hydraulic lash adjusters and both tensioners within these first 3 or 4 seconds. If it rattles while you're driving, letting off the gas and accelerating or coasting to a stop or at idle when warm. Then there may be an issue.

[@mrmarcink1300]

I heli-coiled one for a customer with a waiver due to financial constraints. I used a coil with red loctite and let it cure for a few hours before reassembly. Has gone over 60k since and no issues (yet). Not the right way by any means but this was explained to the customer and agreed was a good solution considering her financial situation at the time.

[@AlexTheCarDoctor]

Oh absolutely, but I always seem to get the knucklehead customers where I try to help them, I explain all the risks and they still get mad if and when it doesn’t work out as if I didn’t explain everything to them 😔

[@mrmarcink1300]

I get it, it's happened to me before. I've come to understand that the customer is not mad at me per se, they are just upset that their car is broken and costs a lot to fix. Always put yourself in their shoes, empathize with them and tell them you will do what you can. They already knew they were taking a chance so there is no need to point it out. Just de-escalate and take care of them. They will get over it.@@AlexTheCarDoctor
