Cadillac SRX 3.0 Timing chain P0017 P0016

I just wanted to make a quick video on my thoughts about why so many GDI engines have problems with stretched timing chains. This particular Cadillac came in with a rough idle and a check engine light with DTC P0017. There is a TSB on this problem. Let me know your thoughts on this topic. I hope this video was useful.

[@carlbernngl]

Thanks for the video and giving a good explanation for the reason why these engine models are having stretched timing chains at such a low mileage. Cadillac should be honest about this one and issue a recall or a very steep discount on the repair. It's so prevalent that it's unconscienable

[@ADVANCEDLEVELAUTO]

+carlbernngl I think GM should've issued a recall. Nissan issued a recall with the Juke for the same reason. All timing chains were replaced free of charge.

[@qq-hk2sq]

Although what you are saying is understood, for the lay person the timing chains don't stretch, they wear at the pivot joints and as a result elongate. Stretch is what they might do if enough force and strain was applied to them say if one was used to lift several tons. The wear has a lot to do with poor oil change frequency and perhaps a bad batch of parts (not uncommon). Keep in mind this engine DESIGN has been around since 2004 starting out as the 3.6L. The timing chain issues appear to have been most prominent starting around 2007 and up when GM implemented an oil change interval that could go as high as 5 figures in the Cadillac resulting in some cars running low on oil from owners not checking it for 10,000 plus miles, as well as the oil just being worn out in that time. I also recall that around the same time GM changed the chain design as well, from the traditional roller to the current quieter design. In order for your theory to be plausible, the wear pattern would have to match the description. If you suspect the high pressure pump as being the culprit, it would stand to reason that the chain that drives that pump would show the most wear. When I replaced my timing components at 176000 miles in my 08 CTS GDI as preventive maintenance with no timing codes, the chains appeared to show the same amount of wear compared to the new ones. It was considerable with a side by side comparison showing near a half inch difference in length. It appears the main culprit for timing chain wear is low quality oil and or extended oil change intervals. The LFX version of this engine uses the same timing components with the same configuration without as many timing problems and probably has improvements in the oiling system. I believe the higher compression ratio the GDI has, contributes far more stress on the chains than a single pump that uses a roller lift arrangement like the 24 valves which is very efficient. Opening two valves at a time against high cylinder pressures should exert a good load on the chains and contribute quite a bit to wear, especially with weak oil lubrication. I use 10W40 Mobil 1 full synthetic and 3000 mile oil changes.

[@luisfhernandezgarcia7769]

quack quack hey great review! You know a lot about this problem, my uncle has a GMC Terrain 2010 V6 3.6L Poor maintenance I believe causes p0017 had low oil helped him with the oil change really dirty oil, only 5/6 quarts in there. Put 5w-30 Mobil synthetic at 135k miles, problem didn’t seem to be fixed. I was able to clean throttle and remove intake to see how the valves look. They look muddy and with so much residue he used Castrol oil and I believed burned oil stayed as residue.... I was wondering if you can help with a suggestion. I’m a good mechanic myself but don’t want my uncle to replace the timing belts. Was wondering if using degreaser or valve cleaner and doing a oil change as adding 10w-40 synthetic or thicker oil should do the trick....

[@MrBdavis99]

The GM port fuel injection 3.6 had the same problem with timing chain "stretch." In my opinion, the timing chain routing is the problem. If they had geared the exhaust cam sprockets to the intake sprockets and just driven the intake cams with the chains, there'd be less tension on the chains as the cams are turning easing the stress on the chains.

[@wojtekb767]

How about the other brands? They experiencing timing chain problems too.

[@on-site4094]

Thanks for sharing the info I’ll remember not purchase one of those amazing chevy shitalacs

[@wojtekb767]

Try to replace timing in BMW. It is placed at the rear so engine must be take out. All other brands have a problems too, some of them even worse than you think ...

[@kaharold]

I Totally Agree..The Reason Why The Timing Chains are NOT Up to Par is Because GM Using Cheap Parts... Especially after 2009 When They Filed Bankruptcy... I Will NOT Buy Any GM Vehicle Anymore that was Made in 2009 OR After...

[@on-site4094]

I feel exactly the same way I’ll never buy gm ever again there good for 150 km then there ready to recycle

[@wojtekb767]

2009 STS and I put 200k on it. Radiator leaks and wheel bearing were replaced. That's it. Now ATS 2.0T and already have 135k. Only coolant hose replaced cost me $30 no other issues so far. Now I'm looking for SRX

[@davidwoermansr]

My oldest GM is a 98 but my daughter has a 14 (I believe maybe 13) cobalt and it's over 230k with no problems yet but her truck is about built so the cobalt will get a rest and become the backup vehicle since the salt has done a number on the body around the fenders and under the plastic under the doors

[@ryanhewett1663]

I appreciate the 2 cents. I think you are right about the chains not being strong enough. do you recommend a chain that will hold up?

[@wojtekb767]

From what I see you can fix it without removing engine? If so I'm not concern about it and gonna to buy one. Will do myself if problem happen. Thanks!

[@cartroublewannafix8611]

Is there a way to adjust the timing without marks? I took the chain out and my stupidity allowed me to turn the the sprocket s individually, which turned the cams. Now I have no idea where I am at. Call me an idiot because I am. 2015 Chev malibu 2.5

[@ronniejr1983]

hi i have a 2010 gmc terrain 3.0 awd slt with roughly 90k. i have code p0016 and p0017. both relate to the camshaft position sensor of bank of a and b sensor. first step was to replace sensors and code came back. im having it looked at monday but i bet the chain on bank one is stretched. probably do all chains as the other one is prone to go soon also. otherwise its a good car.

[@ADVANCEDLEVELAUTO]

ronniejr1983 Acdelco sells the chains as a kit that also includes the tensioners for a fair price. Most times I run into these codes on the 3.0 engine it needs timing chains. I use a lab scope to check the sensors and if they look good it's time to replace the chains.

[@ronniejr1983]

ADVANCED LEVEL AUTO yup mine needs new chains to the tune of $2300 from a side shop. Well let's hope is lasts another 92k

First Question! I called gm dealer to see how much they would charge for the timing chain service, and the service person said they don’t have the tool for it. He said to take it to Cadillac dealer, is that true? It makes me feel like no shop can do it. Second question?i had to tow my 2010 Cadillac SRX to tires plus, cause I couldn’t drive it, and got codes p017,p621,and p690, and they said possible timing chain jumped also! Did your Cadillac read the same codes? And did the timing belt jump!

p0621 is a 5 volt ref. code. that can cause problems with the crank sensor. have to start with diagnosis of that

I find it hard to believe the timing chains will not last as long as the life as the motor. I had a P0016 code and before I decided to spend real money to change the timing chain I changed out the spark-plugs. There you go Viola- Prblem solved. The problem I have is the code is not registering right, it should have gave off a cylinder misfire. Is this a Money SCAM? Hmmmmm

[@ADVANCEDLEVELAUTO]

This video is for the people who have already tried replacing parts such as timing solenoids and cam sensors but still have these codes pop up. This is a well know and well documented problem. GM issued a technical service bulletin about these timing chains. No scams here.

[@tommystryker9954]

All I'm saying is I got a (SRX)P0016 and a p0017, I changed the plugs and it all went away. Something to think about... When my (CTS) gave me a code - a misfire code, I forget what it was but I changed the plugs and again the engine light went away.

[@tommystryker9954]

I take it all back- code came back. We got lucky, it was covered by GM up to 70 k miles, we had 69700. wheeeew, all fixed now for a while. They also guarantee it for 12 months after the fix.
