Ok, so here we go.
2005 Sierra 2500 HD 6.0 4L60E
471k miles
I know for a fact that I have less than 60 psi compression on 1, 3 & 8. Is there anything I need to specifically look at other than valve train and or possibly rings?
So, roughly 6-8 months ago I noticed the oil pressure was low, like low enough for the DIC to display low oil pressure at idle. I've went from 5-30 to 10-30 only to have the oil pressure to sightly increase. I want to say that I'm about to be replacing the oil pump, but is there anyone that thinks the filter screen under the oil pressure sensor would cause this?
I love the truck. It was a retired company truck when I bought it. Yeah, I know, it was road hard and put up wet pretty much. Just looking for advice on where to go from here, and looking for good used 6.0's are rather expensive. Thanks in advance
