HOW TO PREVENT TIMING CHAIN PROBLEMS l GM 3.6 ENGINE PROBLEMS

He's genuine! Stand up guy, straight shooter! My kind of mechanic! I can dig it!

[@Browneye57]

Excellent info. I have a new to me 2013 XTS with 60K - did a Liqui Moly engine flush, then a few miles on an oil change, and then changed again and put in amsoil signature series with a new delco filter. The first oil had been in there about a thousand miles - the dealer did it pre-sale prep. I was ABSOLUTELY SHOCKED at how dark the oil came out, even the second change was dark. Engine is nice and quiet, I'm hoping to get plenty more reliable miles on it. BTW, did a drain and fill on the 6T70 automatic fluid three times - again, shocking how dark the fluid was. Don't neglect these cars - they will bite you back HARD!!

[@rshettle123]

Yep, it's having to clean out a lot. Eventually, the oil after 1k miles will still appear light and transparent like it should. I don't go beyond 3k for an interval.

[@kevinmoler4225]

Great info. I drive a 2013 Lexus ES350 and the oil always looks like it did when I changed it. I'm looking to replace the lexus with a XT6 or GX460. What is the difference between GM & Lexus engines with respect to engine oil color? Thanks,

[@Browneye57]

@@kevinmoler4225 Oil color has to do with how much sludge dirt and carbon it keeps in suspension through the detergent process of the oil. If the engine is clean inside then the oil won't get dirty. I imagine the Lexus engine runs cleaner, but all depends on the environment it runs it, it's age, and the frequency of oil changes. The XT6 uses the latest generation of this 3.6L V6, which is much more durable and reliable that earlier iterations. Dirty oil just means it's doing it's job - and any extended interval, say past five or six thousand miles, should begin to get dark from suspended dirt in the oil. I had a 2001 BMW 3-series that would hardly dirty it's oil in 6K miles, once I got the engine cleaned out to begin with. The first owner went 10K on OIC's, so a few flushes and changes and it cleared out the sludge inside. IMO OIC's should not be longer than about 6 or 7K unless you're doing analysis to determine additive package remaining, and to check for any wear indicators. Blackstone is a popular testing lab.

I just bought a Chevy 2024 premier blazer. I’ve had it for a little while now and I drive it to work around 8 to 10 miles a day one-way. I pulled it in my garage and change the oil at 2000 miles and that oil came out really black at 2000 miles so believe it or not I will be changing the oil at every 2000 mile intervals I know that’s excessive but I had a 1987 Chevy pick up with a 350 in it throttlebody injection and I changed you on that every 2000 miles, I had the engine for 425,000 miles and I still have the truck today with the same engine no problems and it doesn’t burn oil. I know the engines different than this one but I will be changing the oil just like that I can’t believe how black the oil got 2000 miles if you could use the GM oil monitor in your car all they want you to do is make sure it gets past the warranty and then you’re on your own. Thanks for your video. I’m sorry about the car but this is what I have now thanks again you really explained it well.

[@Hummin_Along]

Direct injection gasoline engines in general need oil changes very often. Also I have learned that it is crucial to use a good name brand full synthetic oil. Gasoline direct injection engines run hotter and are prone to diluting the oil with fuel. So you really need to keep up with changing spark plugs too. Now before someone says something about the oil you go with a name brand so you get a better additive package in the oil. Another thing I have learned is direct injection engines prefer 93 octane. Yes the ECM absolutely knows what kind of fuel you are running. I'm a mechanic of over ten years and went to a trade school. Just trying to help people out is all, just like this dude. My wife has a 2016 Traverse by the way.

[@johnnydrakos6407]

My understanding is the direct injection system cool the tops of the pistions which is how they were able to up the compression and run 87 octane in an engine that has 11.5-1 compression ratio. The turbo charged engines however do run hotter.

[@Hummin_Along]

@@johnnydrakos6407 Direct injection has nothing to with cooling down combustion. It just gives the ability to make the fuel injection sequence more precise for fuel economy. The only way to cool down combustion is either through fuel by adding more of it or running a cooler burning fuel like ethanol or methenol. The other way is by injecting something like NOS or water into the intake charge. While you can say that about direct injection those are just happy by products. But DI only has a cooling effect because it has not warmed up by coming through the intake ports.

[@titoortiz5924]

[@ggfgvvn.a.5752]

so i got a v6 camaro with the lfx motor and it says to run unleaded but should i run Primmum since its direct injected and the additives would help clean it or would higher grade gas hurt the car. i haven't been able to find a definitive answer so i've been putting premium gas in it once every 3 fill ups

Confirms what I've been hearing. I just changed the timing chains (195,000 miles `09 cts). Code was saying left bank chain was stretched and I couldn't pass emissions.

Great advice! My car has a 3.6 LF3 motor, I change the oil religiously at 4000 miles - $60 every few months is way cheaper than $6000 for a motor. I arrived at this conclusion by sending out oil samples to blackstone labs and tracking the oil additives, 3500-4000 is perfect, 4500 if there is some reason I can't do it right away. Granted, my car is a twin turbo which is harder on the oil than a naturally aspirated one, but I'm almost at 100k and my engine looks immaculate inside and the timing chains are in perfect shape.

[@unti419]

The new manager at the oil change place I go to asked me what I wanted the oil life mileage set at, I said 5k. Either there is a way to change it or he was BS'ing me. He seemed to know the engine and its problems. So far it seems accurate.

[@Sherman62]

I do the same with my LS based Silverados, which suffer oil related problems as well. They are not OHC, but experience AFM problems and a drop in oil pressure. IMO, factors are poor PCV, small filter element, AFM related oil consumption. I have deactivated AFM and increased oil changes. Things are better. Now I've got a 3.6 Camaro and it is interesting to see such similar problems. Will stay on top of maintenance!

[@robowebowe]

You are a really good teacher. The video is very informative. Please continue to make more.

[@tannerjohnson31]

The reason I know this is because I tried turning the engine over with no spark plugs and was shocked how much force it takes to turn that engine over and realized it was the high pressure fuel pump taking all that Force. After I remove the pump the engine would turn over very easy like the normal engine should but with that pump in there it takes a lot of force to turn that over and all that force goes through the timing chains, the bottom and the front one. Good video thanks.

[@justoyzracing9193]

Should I add a catch can and remove the crankcase vents from the air intake track?

[@jamessowder193]

I have a 2010 Cadillac CTS 3.6. It used oil like crazy. Drilled out the pcv valve a little bigger on both ends. There's specific sizes to drill them out to, so don't just go crazy, look it up and do it correctly. Ever since I did that, it barely uses any at all. Might use a half a quart between oil changes just keeping it at the full line. Actually runs better too. Has a little more response and seemed to gain a little more power after that fix.

[@unti419]

GM came up with a new passenger side valve cover gasket that was also to limit the amount of oil sucked into the PVC. The PVC sucks from a section in the back of that head, and the PCV valve holes being too small created an air velocity that took in oil. Not sure, but I think that came out in 2012. That's what I read somewhere. My 2011 CTS Coupe had the timing chains replaced under warranty by the dealer around 50k by the previous owner so that was probably upgraded. I use little if any oil at all between changes at 105k.

[@vinnygraziano1318]

On these GM 3.6 engines, I change the oil every 2500-3500 miles only exception is a long constant highway road trip and I change it when I get home. Keep the oil clean in these engines, they're fantastic if you do

[@MAS-001]

Hi Boss Automotive, first of all great advice regarding the care of the engine but, as an owner of this engine, I would like to add something to your advice if and when someone does decide to do an oil change or timing chain it is highly recommended to: 1) Remove the old oil filter and Drain the old engine oil out first. 2) Install new oil filter and Add engine flush in the engine before refilling to specifications with new engine oil. 3) Run engine with the combined flush and oil as to the instructions of the engine flush solution. 4) Remove oil filter and drain engine oil. 5) The owner may repeat the engine flush again if the owner thinks it is required (but in truth, I always flush my engine twice) but this requires extra oil filters and engine oil t be used. 6) 2nd flush, Remove oil filter and drain engine oil. 7) Install a new oil filter, and refill engine to the recommended specifications with engine oil. 8) After the new Oil Filter is installed and the new Engine oil is filled to the correct and recommended specifications, the owner must check the colour of the engine oil (via the dip stick) as they drive the vehicle, as soon as the engine oil turns black, change the oil filter and engine oil. Hope this helps. (P.S. By the way, if the engine has suffered neglect from irregular servicing it is always recommended to have the sump/pan oil pickup checked, cleaned or replace, especially if the owner has just flushed the engine and then replaced the timing chain and installed a new oil pump).

Great suggestions MAS.I have a 2012 Buick enclave, 103K.kilometers, great car but on cold starts like in the morning it would idle high and very erratically for about 20 seconds then idle great afterwards..I can hear like the timing chains making some noise and think i need to change the timing chains.. I am thinking about doing a oil flush but not sure what is a good flush to use with these engines, Sea foam, marvel mystery oil etc.. Anyone knows what flush works well with these particular engines. I never go past 7K or 8K kilometers between oil changes.. thanks

[@vincentrobinette1507]

If the engine needs a flush, you've waited too long since the last oil change. I don't own this particular engine, but, I think a much more accurate way to gauge oil change intervals, is based on the amount of FUEL consumed by the engine, and ignore time or mileage. Each quart of oil in the crank case is good for ~30-50 gallons of gas. If you get 30 miles per gallon, that's approximately 900-1500 miles. If your engine holds 5 quarts, that's approximately 4,500-7500 miles. In this engine, it might pay to change closer to the 30 gallons per quart. (I don't know how much oil this engine holds)

My 2015 lacrosse stalled on highway right after an oil change. Towed home it won't start now. Low oil pressure light had start coming on after every 20 to 30 minute trip for a few days prior. I would shut engine off, wait a few minutes and it would be fine. But same problem after about a 10 mile/20 minute trip to work, and on way home. Tensioner pulley was rattling. I hope engine is not seized. I read it may have a sensor that shuts engine off when oil pressure is too low to prevent blowing or seizing engine. Hoping thats the case. Haven't got it diagnosed yet due to money problems. Its been sitting 35 days. Yesterday checked oil it was lower than a month ago when shut down. So climbed under to see if any oil had leaked and can see at bottom towards rear of block under where pulleys are it looked wet. And had oil build up. Stuck hand under feeling around and felt a small rubbery portrusion and clean new oil was on my fingertip. I literally pulled the rubbery stuff of it is white. I don't know much about cars. I guess it is a sealer or something. So guessing thats where the slow leak is. Trying to determine if need oil pump or a gasket. Or if engine seized on me, or if sensor just not letting car start due to leak messing with pressure. I also realized oil change only put 5 qts in and it takes 6. And its low at least a quart since when checked day it got towed home. No stain on ground though. Just oily around whatever part that is down there toward the rear of the engine under the pulleys. I am thinking thats where the oil pump is? By looking at your vid its near the crank.

I'm going through about a quart of oil every month of daily driving of about an hour and half per day city. I have also always used full synthetic and high mileage oil in it.

[@retiredsnowbunnyhunterx5106]

What type of oil you use? Try using Valvoline extended synthetic oil and change your pcv valve. Might help you on the oil consumption. I have 07 G6 GTP with the 3.6 haven't had to add no oil to it at all.

[@jas4925]

First problem the stp oil filter. Second problem cheap oil along with a cheap filter. Third problem following the olm. My parents put 185,000 trouble free miles on a Lacrose and 100,000 miles on a enclave. No issues with 5k oil changes .

[@jeanpierreremond2565]

I agree with you. My 2014 enclave has 96k miles without any issue on the engine. I personally replaced the oil at 5k with full synthetic motor oil and full synthetic Fram oil filter ( I tore apart the old filter to verify the quality of this filter, and I was very satisfied with the internal components) I also opened a cheap filter installed by my local GM dealer 😢 that is why I prefer do it by myself.

Hello! I just got a used 2011 Chevy Malibu with this engine, what oil would you recommend I use with it?

[@bossautomotive7786]

5/30

[@robertocb1348]

Thanks for talking about frequency of oil changes. How about the type of oil brand, like Mobil or Penzoil, etc

[@unitedwestanddividedwefall3521]

You recommend a catch can for these engines?

[@bossautomotive7786]

Yes.

[@jonathanberry3787]

Got a question if you got a chance. I got a 2017 Cadillac XTS. When I start it up there is a rattle for a second or two. Im about certain its timing chain related. I thought it was a bearing in my dual fan but I replaced that and still got the same rattling noise. My question is if there are three timing chains what do you recommend I do

[@retiredsnowbunnyhunterx5106]

I hear that rattle on mines only on cold start ups after sitting for while like over nigh. But after that an driving it an cranking it again it don't make a sound.

[@rschneid1996]

I have a 2011 Buick Enclave with 184k miles on it. I follow the factory oil change guide (7,500 miles) and infrequently add a ceramic additive. I think changing the oil every 5,000 is a prudent suggestion. I also encourage replacing the PCV valve and breather tubes every 75k miles. Enlarging the breather holes on the PCV valve is strongly encouraged.

[@ramongordon3889]

Shalawam King, So I just received 2011 Buick Enclave CXL. It’s not starting, no oil on dip stick. Is it finished ?

[@unti419]

The manager at the oil change place I go to asked me what I wanted the oil duration mileage set at, I said 5k. Either there is a way to change it or he was BS'ing me. He seemed to know the engine and its problems. So far it seems accurate.

[@thecircleoflove7557]

Nice video. I love your explanation.

[@autiemuse]

My 08 Acadia went 245K due to frequent oil changes, full synthetic. What kind of engine "flush" do you suggest?

[@p.drichard]

Can you put a link as to which brand of fuel pump, timing chain, and all parts that you use to change these parts?

[@myfavorites1016]

Forgot to ask you , since my 2013 chev impala lt has that 3.6 with issues of timing chains , do you think by me switching to FULL SYNTHETIC oil and changing oil every 4 ,000 would prevent my timing chain from stretching , what do you think , cause im not gonna pay the money for higher priced oil if it wouldn't make a difference, thank u

[@unti419]

I use Castrol Edge full synthetic 10-30 High Mileage oil, it's really good. A 5 quart jug is like $22 on Amazon, so it's not really that much more expensive. The engine takes almost 6 quarts so buy two to have some extra. I would never use cheap oil like I did in my younger years. Re-refined oil was 39 cents a quart back then and I used the hell out of it.

[@jamesk.herder624]

Thank you Boss Auto for your video. It was very informative and helpful. I have a 2017 3.6 , I’m trying to increase its life. I change oil every 5k - 6k miles. When should the spark plugs be changed for that engine? Keep up the good work.

[@Motolympics]

Hey man, I was thinking of buying either a Regal with the 2.0 Turbo or a Lacrosse with the 3.6 V6. I always do oil changes every 3k with full synthetic along with AC Delco filters. If I keep running that schedule will either of these engines give me a problem. And which will be the better engine till 150K?

[@bossautomotive7786]

The 3.6 is a better engine in my opinion and experience. If you keep to the 3k oil change, full synthetic and high flow oil filter.

[@Jack51971]

Boss? What do you think of the GM 3.9?

[@Lunarphantom99]

I have a 09 Malibu with the 3.6 over 200k miles, my recommendations is keeping the oil changed, once da oil gets dirty check engine lights come on etc, every 3 or so months I get a oil change #idrivealot oh I also use #Seafoam every now and again, in the gas and oil case, timing will be off if the oil is bad

[@retiredsnowbunnyhunterx5106]

​@@Jack51971The 3.9 is good. Not a direct Injection engine so you won't have these problems but got plenty of power.

[@jamesgamerguy3]

what kind of engine flush you recomend ?

[@bossautomotive7786]

Just regular engine flush

Pcv valve too. Easy but critical. They like catch cans. And a catch can too.

Catch is a good move

[@Urbannestquest]

Thank you for the information. I learned a lot. I will change me oil every 5k from now on.

[@MrMckenzie2403]

You nailed it! It's a engineering F-Up. Saabs don't have this issue. Better heads do to a turbo. Also another big thing! its a High Feature Engine! High compression! use the gas gm tells you to use! These motors are none like any motors in some since. They are as small as a 2.8 and can be punched out to a 4.0 No motor can do that with out sleeves. This one can. Look at the vent valve on the covers. One side it is big while The other is tiny! Take that cover off and take a bit or something open it up! That will help that side vent better. Oil and gas is all this motor ask for. Don't cheap out! It will treat you well!

No way to really check the chain, I would change the Chain at 90k to 100k

have a 2019 xts amazing car but my 2009 cts is a nightmare . I do oil changes all the time and had the timing chain job did twice now have a p0008 and p0018 timing codes on again. also a oil pressure code and its a new sensor on that too. I changed the cam sensors and vvt sensors. crazy part is car runs rough and less power choppy. but at times drives smooth full power and perfect. got me thinking how would the timing be off if the car drives good sometimes. probably a phantom problem like a wire in a harness or something odd.

I absolutely LOVE my 2015 LTZ!! Cranberry Metallic with Black Leather, & the 20" wheels. I'll hit 70,000 miles this Jan. 2022. One CRUCIAL thing I do for my 3.6 VVT is adding a cup of Seafoam to the Engine Oil about a month before an Oil-change. This really cleans things up internally!! And yes...ALWAYS Synthetic Oil (Mobil 1). I've checked my Oil a month after an O/C, & it's still pretty clean on the stick! I also add 1/3 bottle of Seafoam to our cars gas-tanks 1/x month when they're @ about 1/4 tank. Further.....the ONLY ONLY Gas they EVER see is Certified Top-Tier NO-ETHANOL Premium from either Shell or Holiday stations. I realize fuel isn't sprayed over the valves in our DI Engines, but it helps reduce carbon buildup a little. Yes.....I realize I have a "Flex-Fuel" engine. BUT >>>>> there's no way in Hell I'm using Ethanol in it!!!!! The CTT Fuel helps keep Injectors/etc. a little cleaner. My Girl runs STRONG!
