It might be the L87 in a 2018 truck. the 8th digit is a J, which sounds like its the L87
2018 6.2 Chev gasoline engine failure
- Thread starter cdlamb
- Start date
If the cam & lifter are both bad, how do they ensure the oil galleries arent contaminated with filings or shrapnel?
Does it require a complete disassembly to clean it out? What about removing the pan and cleaning the oil pump pickup screen?
They remove the intake and they remove the heads in order to get to lifters.
The lifter typically collapses internally, so there isn't any shrapnel to hunt down.
On the other hand, if you had the bad type of failure, where the lifter roller piece wears out, and you have metal to metal contact between the camshaft and the body of the lifter, then you probably need to drain, refill and run the engine for 5 minutes a couple of times in order to get all of the debris out of the oil cooler lines.

sounds like he is going to be in the ballpark upwards of $11,000 CAD at the Silverwood Chevrolet dealer in Edmonton Alberta.
Seems a little high to me, but he agreed to their "certified service inspection".
$90 complete veh. inspection
$941 to remove head
$6328 Replace Lifters And inspect cam (cam was found to be good so no need to replace saving $5855
$518 Replace Engine oil cooler lines ??? he didn't notice any oil leakage or require topping off.
$748 Replace vacuum pump ??? What is this for? Does it contribute to the AFM cylinder deactivation?
$1033 replace rear pads & Rotors, (we can do this ourselves for less, I am sure)
$1100 replace left inner & outer CV joint boots??? I don't know if there was an issue, and if they doubling up on labor?
Additional Cautionary recommendations:
$190 top off brake fluid, which shouldn't be low,
$170 four wheel alignment
$76 air filter replacement
Hopefully they haven't done the extra additional service without checking in with him.
he is 23, I will probably be the one footing a large portion of this bill
I haven't seen an updated estimate, but after they add shop fees and additional expenses and taxes it wont be a cheap fix!

Skip the brake fluid exchange , alignment , air filter , rear pads and rotors , axles and you have significant savings by doing yourself. Absolutely do the oil cooler lines ( likely leaking at a crimp) , vacuum pump likely has a hard brake pedal or isn't building up quick enough causing a hard pedal?
Are the oil lines known to leak?
I am 3 hours away. I wish I was able to see the issues they are pointing out.
Hopefully they are able to remove the lifters, seems they cause issues and if they can't remove require complete engine swap.
I just hope they aren't taking advantage of a young man. This bill would really set him back.
Thankfully I am able to help him out, using my line of credit at a reduced interest rate. I told him he could make payments on the principal and I would write off the interest, essentially offering him an interest free loan.
I will likely cut him a break and pay it off early.
I expect the complete bill may come to as high as $15,000 CAD
I hope he is telling them only to do the engine.
I am sure some of the other stuff we can tackle and save shop rate fees.

My shop software has pictures I can send in the vehicle inspection ( digital) don't hesitate and call for pictures. Any good technician/service writer is going to understand and take a moment out of there day for pictures ! Not sure if the newer ones do but the body style before it did and the body style before that. Trans cooler lines and oil cooler lines !
With their estimate they sent out stock photos showing cv joints and brake rotors.
Not very hapoy with this shop.
He initially took it to a Mazda dealer to get the code reader and an initial diagnosis, just because it was right next to his place of work it was parked after first experiencing symptoms and CEL.
The Mazda dealer pretty much made a video of their process.
I am impressed with this place.

If your not impressed with the gm dealer . Definitely don't hesitate to find one you are impressed with ! What does Google reviews say about the place ? When I worked for gm our local dealership truly cared about the service experience. The Chevy dealership down the street just seemed to care about the sale ! Your spending a lot of money. Make sure you feel comfortable with who you spend it with because if there is an after repair issue you want to feel it will be taken care of !
How do you pull it out of there in a state of disasembly? Still going to be charged shop labor on what they have done, then hope all parts are accounted for or next shop be questioning you.
It's a certified Chevrolet shop, they should all be held to the same standard.
Hopefully there is a recall issued and he can get it partially covered. Older pre emissions engines from the 80's woukd make 100,000 miles with less maintenance.
With the technology and oil improvements these trucks should go 250,000 with minimal maintenance.
I just hope they not taking advantage of a 23 year old man with little experience dealing with costly issues.
He owes on the truck and it's not worth much if the thing won't run, but can't afford to sell I at a loss now with this much into it.

I agree absolutely. Just ask for the pictures of the additional recommendations. Then decide if they are worth it to be done !

Never had one leak - guess that’s the perspective difference between a lifetime GM owner vs a GM mechanic …
Disagree. Modern cars' engine computers compensate for lower octane gas.

these trucks will aggressively pull timing as needed to keep from spark knocking.
I have run regular, mid grade, and premium (recommended) in our 6.2L L92 powered 07 Denali. Gas mileage deceases (timing gets retarded) when not using premium.
I have gotten knock detection warnings on the digital information center a few times. No cracked piston(s) thank goodness.
Cracked pistons do occur and are discussed on a GM SUV forum I've been a part of for almost 6 yrs.

your 07 is not DI. DI began in 2014 with the body change.
