$3K to change an oil pan gasket?
Do they have to pull the engine to do it?
I think I have seen YT videos changing it it a few hours.
Ya, the local GM dealership service dept. said the motor had to be raised up about 4" to remove the oil pan.
BUT, they also said it was leaking at the oil filter mount; this mount is machined into the pan LR corner.
When I got home I put the truck on ramps and checked tightness of pan bolts; all were quite loose according to my ¼" snap-on torque wrench. The 2 bolts below the rear main were finger-tight.
I asked the dealer why the inspecting tech did't find those loose bolts, he replied "well the tech would have discovered them when he began to remove the pan". That's when I loudly said BS! and told him motor oil is cheap by comparison.
I'm still hung up on him saying the 5.3 normally begins leaking oil around 80K miles.
I thought about pursuing this and ask for the GM, but I felt my BP rising already, and I used to have a short fuse anyway.

I'm at 106,000 miles on my 5.3L 2016 Sierra. No leaks or engine valve ticking.

Post warranty, I avoid the stealerships, in favor of smaller, local shops.

I have a 2013 silverado with a 5.3 and 151000 miles. No tick no oil leaks. I have used marvel mistory oil a bunch of times and shift to M5 .

Bought one of the cheaper Amazon versions of the range and installed it on my wife's 2011 GMC Yukon Denali with the 6.2 and when we traded it in last year it had over 250k on it and not 1 problem with the motor, I am convinced shutting off AFM is a good thing, I used a Flashpaq tuner to turn it off via the trucks computer on my 2012 Silverado with a 5.3.
