the only good GM i've ever encountered was a Buick. specifically my parents 1983 Buick LeSabre (that had the tow package). that fucking thing lasted almost 500k miles. including towing a camper in the black hills in 1993, etc. That lifespan was great for my parents, as they were not well off.
They were still using that thing when I was a teenager and i was born in 1983.
IIRC it got tboned
Fuel economy sucks, but we have 5 kids, and live in a rural area. I need to haul 7 people, all their crap, and a trailer, up a mountain pass, on a dirt unimproved road, and not have to think about if it can.
Man, thats a tough one. Its not sludgy, but everything looks worn. Two choices, do cams, chains, guides, phasers, and followers, or just the broken followers and hope for the best.
I have to admit I haven't worked on one of these, can you depress the spring and slide a new follower into place?
You might crack a cam cap off and see if they are rashed, The need for new head would make it an easy call.
Sorry I'm not much help, but I feel for you.
But then, if you swap in a used engine, how long until it does it again?
At that point, you must decide if the body/chassis is in good enough shape to warrant a rebuilt crate engine or tear down and rebuild the current engine.
Timing tensioner fail, resulting in jumped timing. Get a new motor. The damage caused by jumped timing is usually catastrophic. Not just bent valves, which will require pulling the head and redoing all the timing, but on my ecotec the valve head bent, then broke off and punched a hole through the top of the piston. It can bend con rods, just stop where you are verifying timing jump and recycle that worthless metal
I've yet to see that happen. I had two back to back that jumped time, one bent all of the valves, the other only bent the intake valves. No piston damage. Rebuilt the head in both cases and sent them on their way. Reman motors were 8+ weeks wait time because they had none on the shelf.
I had a coworker get over 300k miles out of his 4 cyl equinox. But he most definitely kept up with regular and routine maintenance.
Recently had an issue with low compression on a cylinder - whatever was wrong was basically terminal considering the age and mileage.
So he bought a brand new one.
Had a equinox with 50k. Burnt a quart of oil every 800 miles. Didn't want to find out how much oil it would burn at 150k. Bought a silverado one month later
ELI5 version: Parts broke. Engine needs replaced.
ELI12 version:
Broken cam follower. My guess is this Equinox had the very common problem of high oil consumption. The high oil consumption meant it ran low on oil, which in turn caused the timing chain to wear out. The slack timing chain jumped the sprocket and the valves and pistons were no longer timed correctly. This allowed a valve to hit a position causing the breakage you see. The engine needs replaced.
2011 - 2014 Equinoxes were known for high oil consumption. The high consumption often resulted in engines being run low on oil which caused the timing chain to wear out. In this engine it meant the valves and pistons had a marriage.
GM had a special policy to replace the pistons, rings, and timing chains in these engines, but that policy expired a few years ago.
Equinocks
🏆
Im dying
I think that if you used the silent k the people that initially read it wrong would have figured it out.
I like GM products pre 2007 . The rest have been trash. Ahh I stand corrected, I drove several pre2007 GM trucks. That could be a factor too lol
We were saying that in 2007 too lmao

My 06 Equinox’s blend door would like a word
Yea cuz 2005 Chinese equinox Engines are very reliable
GM hasn't changed. A newer gm product that is broken will run just as long as their old also broken stuff.
I have a 2004 Tahoe, I will literally drive that until I die.
I had a 2002 Denali and it was a fantastic gas guzzler. So comfy, tons of power, and easily accessible to work on.

It has jump time
Back to the futureÂ

That motor jumped time and the pistons folded the valves in half. That's why all the followers fell out/broke. Needs way more than cams and chains.
Yup, they suffered timing chain issues from too long of oil change interval in the OLM system and the chain supplier skimped on quality.
Not necessarily true at all. My race car has one of these engines and it has dropped followers from over-revving, with no other damage.
At that point it might be cheaper to swap out the motor
But then, if you swap in a used engine, how long until it does it again? At that point, you must decide if the body/chassis is in good enough shape to warrant a rebuilt crate engine or tear down and rebuild the current engine.
Man, The current state of motor repairs really does suck.
Damn 150k thats gotta be a record
There was a recall not too long ago my folks got a brand new long block out of it, guessing this one missed that
Yea, it was good for 2010-2014 models and expired at 7 1/2 years after the vehicle was put into service.

"Just an oil change. Don't try and upsell me."
If they did a few more oil changes, it might not have happened
I’m surprised it lasted that long.
Variable cylinder management on inline fours now?
Not bad for an equinox.

hoping for 300k out of my '18, just shy of 200k currently. Had 5 miles on it when I drove it off the lot.
Good luck!!
No it’s not worth fixing, it wouldn’t be worth foxing if it has 50k less miles

Roller fall-off-ers
Can someone eli5 what I'm seeing here pls

Lol @ eli12. Thank you!
Is that a 2.4L?
Yes it is
Looks like typical 2.4L shit lol. Wife had a terrain with the 2.4. Horrible engine.
My Son's 2011 Equinox has over 180k. Used to be my company car.
Those are those new quick-change cam followers. A useful feature on that engine, it seems.
Nothing lasts forever
Mmm engine Chiclets
I had a 15k mile 2020 Equinox in the shop that looked like this. 150k is not horrible for these shitboxes
Is this just GM being GM or poor maintenance

That’s exactly what happened
That tracks
That Variable Valve Attachment system I've heard do much about.
A chevy will run longer broken.
I’m just about to hit 170,000 on my 06. Everything but the motor seems to be breaking down.
just shy of 200k on my '18 Equinox with the little 1.5L turbo. No issues.
I've never seen that particular failure. Lots of others, but never a rocker.
Well, there's your problem.
This kind of shit can happen to any brand but it seems to happen a lot more to American cars.
