i work at a gm dealership.... call gm customer service and blow your stack. you might have to pay a couple hundred for a deductible but they should cover it. go above the heads of the dealership. start a claim with gm stating your case of your motor repair history and you have had problems in the past. then Gm will call the dealership and they should good will it

ps make sure if its FWD the engine you get is from a FWD vehicle also..i think the front drive axle goes through the oil pan..or i may be thinking of the trail blazer SS.

Axle through the oil pan is Trailblazer. As far as replacement, the dealer will not cooperate, but google the GM warranty escalation procedure, you should be able to track down the phone numbers or E-mail addresses of higher ups who will listen if you complain loud enough. If your Client is a multiple GM vehicle owner it should help.

the 08 and up 5.3 long blocks are the same. You're looking for a GEN IV engine
The came with VVT or DOD . . . meaning it would go into 4 cylinder mode, these lifters are known for failing and wiping out a perfectly good engine

So since this motor is displacement on demand and flex fuel, a 2010 with same features should be a direct fit, right?
He claims he exhausted all options, I think more than anything he just wants it fixed quickly not tied up for a long time. The money is not the big issue, it's the loss of a vehicle. It's his wife's ride and she loves it.
Sounds like this might be the case, it has lifter noise and a dead miss. I have done zero diagnostic on it, but it came in on the hook and when I moved it inside the oil pressure dropped off to less than 10 psi in a matter of a minute. It's obviously sent metal all over.

i think i have a complete cam, lifters, gaskets laying around for that truck if you feel like looking into it vs tossing a motor at it. GM customer service!!! 1-800-222-1020 call and tell them you own a fleet of gm vehicles for your business and the dealer obviously misdiagnosed the problem cus its still doing the same thing but now your out of warranty by milage but still in by time

RT- I think you can get a reman Long block from GM and will have a warranty.
X-Driver- The AFM- active fuel manangment or DOD as it is also known had issued with oil being splashed inside that a baffle was added later. Its the rear cylinders - check your plugs if they are oil fouled get it fixed. This is a known issue that GM may do a secret warranty on- they may offer to split the cost with you if it is an issue. ALL the automakers do this including the NOT infallible Toyota.
