2007 Yukon SLT 5.3 to 6.2 swap, VVT cam replace options, and long tube headers
Hi, I have a 2007 Yukon XL 1500 4x4 with 5.3L 4L60 with 240k miles that is recently burning a LOT more oil and losing coolant (slowly). I suspect head gasket failure. Amazingly no issues from DoD so far. Rather than go through rebuild and DoD delete on the 5.3, I got a deal on a salvage 2007...- k99ja04

Low oil pressure at idle, pulling my hair out, looking for any and all options.
So it started about a year ago, once engine gets to operating temp (coolant needle straight up), the traction/stability light would come on, indicating an issue and then shortly after a p0011 code, “A” Camshaft Position Timing Over Advanced or System Performance Bank 1. Nothing would change in...- Levin37

2011 Yukon engine dropped a valve... 186k AFM Flex
Has very loud ticking noise, #5 was not firing. I took the drivers side valve off to find #5 intake valve not seated in the up/closed position. Put compressed air in through spark plug hole, air was blowing out throttle body. I guess the valve somehow contacted the piston and bent. I tried...- stapleto

6.2L V8 - 2021 owners
What is your real MPG? 2WD or 4WD? (I don’t need a 4WD so I ordered a 2WD). I, so far, go to work 4-5 days a week 1 mile away but tend to go around town to run errands and such. (I’m figuring like $200-$300 for gas a month) right now my 8 yr old, V6 Acadia is getting like 11 MPG but I fill...- Chloe_21
