I put this here because I didn't know where it otherwise belonged so forgive me if I'm wrong.
I have a Chevrolet Equinox that has done just 30,000 miles in two years from new. It has always been dealer serviced but last week it needed a replacement timing chain! Now OK it was done under warranty, but now I'm nervous. Do I keep or get rid?

those engines are hard on oil and they were set to too long an oci. Also parts were updated.

I wouldnt worry about it.

If it,s because they can prove it,s because they have a series of bad chains. And the new one is improved. I think your fine. If not I would have trouble sleeping at night.

In witch way did it fail?

It depends if the dealership fixed it correctly. Since you have a 100k powertrain warrenty see what happens. If something fails again then I would get rid of it.

What year? What engine? Oil type? Did it fail outright, or just noisy and the dealer noticed?

I know some Ecotecs had TSB s on the timing chain oiler.

I know it was hinted at above. But it's clear that extended oil change intervals are tough on internal chains. This is the case with Ford modular engines, Chevy small blocks, and now the balancer chains on modern engines.

We can argue about UOA results all day long. But the real world results are clear. Some engines suffer chain issues with extended drain intervals. And, I'm sure the chosen viscosity is part of the issue too.

Sure, the parts are better. But they are still conventional chains. And the stress levels did not change.

Back in the late 1960s I had a Mustang with a 289 V8 and no one ever talked about timing chains or tensioners. They were just bulletproof. Then timing belts and now back to timing chains, but now less sturdy.

Timing belts are asinine.

Let's save $20 when manufacturing a car, only to cost the owners of the car multiple thousands of dollars ...

No. Long Chains are unrelaible and foam the oil. A dry timing system is preferred. Agreed the maitenence of the belts should be easier regardless of packaging.

Ive NEVER had a trouble free to 100K wet chain timing system (OHC). Trouble, trouble, trouble.

OHV short chains on V8/6 are not typically a reliability issue but THOSE are nylon gear overmolded and were usually toast at 100K also.

I like chains over belts, but I have never liked having yards and yards of chain flailing around at high rpm. A nice short chain to the cam in the center of the block works for me. I rarely have to work on them, too.

I like pushrods for packaging, there's a reason the new Vette has the LOWEST center of gravity Car and Driver has ever measured in any car!

The Nox has a new chain that is supposedly improved, I'm sure that issue is being put to bed when combined with more conservative OLM programming.

The long OCI on these engines isn't helping any, major reason why GM went back and reprogrammed the OLM on the Lambda platform vehicles. Our 08 Acadia used to go close to 10k with the OLM after the reprogram it was down to 5k max and now our new 2011 Acadia hits 5k ever time when down to 10% OLM. To me either keep it simple and do 3k oil changes with conventional or 5k changes with PAO synthetic.

As for timing belts, yep they cost more to maintain to a point but like in Honda's changing the belt every 100K isn't that bad if the rest of the vehicle didn't nickle and dime you to death by that point.

Thats why quality oil's have an defoamant as part of their balanced additive pack.

Also arco from previous posts you seem to have trouble with all engines <100k regardless.

I have never had a timing chain issue. OHC or OHV. Some engines well over 200K. All at 10K OCIs.

Yes some early 3.6 engines had timing chain issues. GM extended the coverage for these to 120k miles/10 years regardless of ownership. Most models effected were CTS, Traverse and Acadia and variants. Years affected are mostly 2008-9's. I had the chains done on my 2008 CTS and my Dad had his 2008 CTS chains done too. His at 42k miles using OLM and Redline. Mine at 74k miles using Mobil 1 and 5k mile OCI. I know of 6 other people who had chains done too on Acadias and other vehicles. No problems at all after repairs.

Feel confident that you will be okay after the repair. Better parts are used and if chains are not done right...you will know pretty soon.

If they did it right, you should be better than new.
