Hey Gang, I'm driving a 2001 GMC Sierra 1500 with a 4.8L V8. Looking for a little bit of help with a Compression diagnoses. Info is as follows; Compression - 115 - 8 7 - 110 110 - 6 5 - 95 120 - 4 3 - 115 115 - 2 1 - 95 Its not Burning oil, burns a bit of coolant but nothing noticeable out of the exhaust and the coolant doesn't look contaminated. there a slight knock/tic when i start from cold but only for the first couple seconds. No drivability issues but she does burn gas pretty decent of late. Had a misfire issues a few years back and replaced all the injectors not sure if that caused any damage. Theres a slight leak in the exhaust manifold. Otherwise it's runs great. Was thinking of doing the head gaskets and valve cover gaskets and having a look while i was in there but i was hoping to get a few educated guesses to what i might keep my eyes open for. Thanks in advanced.

I just bought a new to me 2014 GMC 2500 HD Denali and I got a really good deal on it because my better half works at my local Chevrolet dealer and it has 142k miles on it. The truck blew a head gasket on a family vacation and they chose to trade it in on a new truck to continue their vacation. The truck has been deleted, EGR and DPF, and it has 142K mostly highway miles on it. Other than the delete everything else is stock and it runs fantastic and I live in Idaho so I don't have emissions testing. The mechanics at the dealership said the truck was in great shape and that I should get it. I got a print out of the repair and the parts used on the repair is three pages long and it also has quite a few hours of labor in it and it would probably cost $5k for the repair. The truck is fast, amazingly clean inside and outside, and under the hood is immaculate and I want to love the truck but I have a nagging fear of high cost repairs. Is a blown head gasket a common problem on the 6.6 Duramax with stock boost?
