I just bought a 2004 Avalanche and it has the 5.3 in it. Is there anything that is notorious about these engines? It has 72K on the odometer and runs well. It's a variant of the LS1 right?
Piston slap and lifter noise. Very ocassionaly you will see low oil pressure from a stuck bypass valve but it affect earlier gen 3 engines and I haven't seen it with the 02 engines. If it is quiet and runs good you got a good one.
dont worry about em, theyre strong. 03+ got the better oil pumps. They sometimes have piston slap when cold, but it doesnt hurt anything. if you break it, you can get a low mileage one from the junkyard for $300. theyre a dime a dozen
