2011 Equinox 2.4L engine swap with donor from 2013 Verano

I'm trying to help my son and daughter-in-law get their 2011 Equinox (original LAF engine) back on the road - it succumbed to the dreaded "Oil Consumption and Timing Chain" engine failure after a long drive at Christmas. Their Equinox has about 150k miles on it.

I was able to inexpensively source another 2.4L, this time an LEA-code engine, with about 103k miles on it from a 2013 Verano that was totaled after it was hit in the passenger rear door.

I'll post my progress on the engine swap here, but I'd appreciate any BTDT advice. I've been lurking around the forum here trying to gather information on the 2.4L engines and their failure. For now, my goal is just to get their Equinox back on the road. I plan to go through and replace the timing chain and guides before installing the donor motor, and I'll check for the clogged PCV orifice, too.

Here is the donor motor coming out of the Verano. I had to remove the A/C compressor to get enough clearance to angle the engine/trans out the top of the engine bay.



The build date of the Verano is Aug-2012, so from what I've read in other posts this may not actually have the better piston rings and may still have oil consumption issues I can only hope that the engine was at least running when the car was hit and totaled.

Your swap should be very straight forward. I believe the throttle body will need to be swapped on to the LEA engine for it to work. Might be a good idea to check which intake cam and intake cam phaser the old LAF engine had, as there are two versions. ( 2011 LAF engine should be the same as a 2013 LEA but it would be wise to check and be sure) . There was a good write up last Sept. - Oct. do a search for " 2010 2.4L LAF to 2016 2.4L LEA Swap "

Got it for $130 => $100 + $30 for a 1year warranty

I did stop in at a Buick dealership on my drive home last night and asked the service manager to look up the history of the donor car's VIN. Other than the initial delivery in November of 2012, and some sort of recall (a SW update on one of the ECUs) at the time of delivery, there was no other GM service history for the car. So, there had been no piston-ring work done, to date - at least not in GM's network.

A friend of mine bought a 2012 Equinox for his son in the last year, before learning about the oil consumption issues, and their 'nox is consuming a lot of oil now. At first, the dealership was saying there was nothing they could do, but then after reviewing the service history he found that the rings had already been replaced once at 60k miles. So, the dealership is seeing if there is anything that can be done as part of a warranty on the previous ring work.

That was one of the posts I reviewed before starting down this process for my son and daughter-in-law - thanks!

I've got the donor engine on a stand, now, and am ordering the parts to replace the timing chain, tensioner, and guides as preventive measures. It turns over by hand (and I felt resistance/compression), so that's a plus.

Also, looking at the Equinox - I think I'll be pulling the motor out the front, as the bumper reinforcement is just bolted on, and once it & the radiator & AC condenser are out of the way it is a straight shot between the unibody/frame rails out the front. I should get to that removal this weekend, I hope.

Sounds like a fun project. Where do you live ? If you were somewhat close to upstate NY, I would invite myself over to help. That, and doing a fwd clutch are on my bucket list.

bigb12359 - sorry I didn't see your message earlier...I should have gotten an email notification, but didn't...I'll double-check my settings.

VIN of the donor Verano was 1G4PP5SK9D4113848 . The preventive maintenance parts should have arrived at my son's by now (timing chain and guides, new plugs, etc.), so we can start prepping the donor engine. Also, on the donor engine, there is a plate at the top of the timing chain cover that has a label with some sort of barcode and numbers on it, but they are worn and not readable - is there any value in knowing the information on that label? Is it an engine serial number? Is there another spot on the engine to get that?

I should get the dead engine out of the Equinox this weekend. I think my plan is to remove everything in front of it, unbolt the torque converter from flywheel (through the starter opening...starter removed), and then separate the engine from the transmission and bring out the engine only. If I have my stack-up (or stack-sideways, in the case of the engine and transmission) correct, I should only need to shift the engine about 3/4" to the passenger side to get it to clear the transmission housing and come out the front/top. With the engine mount from that side loose or removed, there should be enough clearance to shift the engine that far to the passenger side. Can anyone chime in with some BTDT experience to back up my analysis/assumptions?

A coincidence (or, maybe instead, not surprisingly): I had my in-laws' car at a local shop for some other work to be evaluated/diagnosed - and sitting in their parking lot was a snow-covered Equinox. When I inquired, it was there because of a dead engine - a 2.4L that blew the rear main seal. Ugh.

Let me guess - their VIN was not in the "magic list" either !


It is crap like this that makes me second guess my loyalty to GM.



I am certainly happy in my decision to unload my '10 4-cyl. before I was faced with any huge expenses. Thank You forum members for opening my eyes !
