I just hit 91K on my 2018 TD Equinox, and the timing chain has begun the 'Death Rattle'. The sound is most prevalent once the engine has warmed up, there's low load on the engine (above 2,000 rpm just prior to an upshift), and the oil pressure is on the "low" setting (24psi-27psi). I went back through my documents and realized I'd done 18 oil changes since I got the vehicle, and I guess that still wasn't good enough (found pieces of plastic from the guide in the used oil!) I've already priced out all of the parts required for the job as I'm pretty certain I'm going to have to do this job myself or pay out of pocket; surprisingly, all of the parts, everything (including a new oil pump) aren't even $300.00. Has anyone already had this work performed or done this job themselves? My concern isn't the timing job part, but rather getting to the rear timing cover itself. I don't have access to a lift so I'm either looking at pulling the engine and transmission out from the top together, pulling the engine out the top and leaving the transmission in, or lastly dropping the transmission leaving the engine in. I just want to know if anyone has done this so I may have a better idea of how much time is involved and how best to access the rear timing cover. Thanks in advance for any input.

Thank you Flüstern Deez . I am very interested in this topic as I am contemplating buying (or not) a used Equinox diesel.
Well, all of the parts have been ordered to perform the job. I located a shop that would perform the work for a very competitive price and have also found a place that rents their shop lifts by the day or week if I decide to do it myself. I’ll update this space once I get the ball rolling either way.

@Flüstern Deez : Wow! This is big news! With that mileage and that many oil changes - you must be the original owner?

Also ... is this the first Timing Chain failure reported here for a Gen-3 Equinox?

Plastic pieces in the oil + chain rattling sure seems to be a smoking gun.

Is there anything unusual about the Diesel engine or your use case that might have precipitated this?

Did you ever check with the dealer about warranty the power train is supposed to be 5 yrs 160kms. And pieces of guide would be a definite engine problem
I think it’s a 5-year, 60,000 mile (in U.S.) Powertrain Warranty, and @Flüstern Deez is at 91,000 miles.

So what was the price quoted?

So what was the price quoted?
$4,250.00 for labor from Miami Lakes Chevrolet. I found a local independent diesel shop that I'm going to have do it for $1,848. The timing chain has yet to fail; it just rattles like crazy at certain loads and rpm's. It's a known issue that US GM is not providing assistance with either by extending the warranty or recalling the poorly engineered timing component. Vauxhall in Europe IS honoring the issue by either installing a gasket behind the timing chain tensioner to prevent the issue from occurring in the first place or replacing the chain and tensioners provided it was well documented prior to 12/31/21 and the vehicle has less than 100,000mi. I've done nothing unusual with the vehicle. It's driven daily here in South Florida in crazy Miami traffic, but after reviewing the Vauxhall and Opel forums in Europe and Asia, this problem is very common. There are numerous tutorials on the replacement procedure mostly performed on the Mokka (AKA Buick Encore/Chevy Trax). It seems to be the only weak point in what's arguably one of the most power dense diesel engines GM has ever made (second to the bi-turbo version used in the Astra).

Hi Everyone, does anyone have a parts list and do I need to separate the transmission as I have seen in some posts?
Do you want the full parts list for the timing chain job? And yes, the transmission and engine must be separated in order to remove the lower timing cover.

Here's the list of the timing components I ordered to complete the timing job. The only other part you need to prevent premature failure of the timing guide is gasket 55515025 which is available in Europe or Asia from Opel or Vauxhall. I was unable to successfully order it from any country there, so I had to improvise. I ordered 12589479 which is similarly shaped, but larger in size. I used tin shears and a Dremel to create the same gasket. The only other part I'd suggest replacing if you can find it is the oil pump (55509127), but at the time it was made of 'unobtainium'. The Equinox is at the repair shop now and should be back to me next week. Let me know if I can help out with anything else. :)

@Flüstern Deez : well ... at least it's just a bunch of relatively inexpensive parts. I wonder how this list compares to one for the same repair on the Gen-2 Equinox (2010-2017). Probably very similar, right ... except some people also replaced the Cam Phasers, too (IIRC).

Doesn't this engine also have the INTAKE and EXHAUST Oil Solenoids?

I know there are two solenoids for oil control, one of which I replaced already (the mechanic who was performing the torque converter replacement broke the harness off and thought it would pass QC). There’s the oil pressure control solenoid located at the bottom of the block on cyl #4 that controls the oil pump pressure. There’s a secondary oil piston squirter control solenoid that’s near cyl #1 if memory serves me correctly. I haven’t priced out the parts for the earlier model Nox, but I can’t imagine they’re more expensive than the diesel.

Well, engine is out and both rear timing covers are off. It appears the upper and lower guides are worn the most. You can see the difference where you can see the full side of each link vs where you can see maybe 3/4 of each side. Should have it back before the end of the week if no other problems arise.

You mean ... the Chain cut into the contacting surface of the Guide? Do you have pictures of that?

Interesting. . . . gears driving the timing chain and another gear driving the other cam shaft it appears.

Yes, ‘scissor gears’ as they’re called are used on the camshafts as well as on the crankshaft to reduce the noise created by the timing components. Placing the timing cover under the bell housing further reduces the noise typically heard from this layout.
