Sick LB7
Just bought a 2003 3500 Silverado with LB7 Duramax. Noticed after several days the pick up smokes and has a lot of blow by. The pickup is making oil and losing water. I did the oil from dipstick to white towel test and it doesn't seem like there is any fuel in the oil, but the pick up loses oil pressure after you drive it. I did a compression test with results as follows:
1 - 410, 3 - 400, 5 - 350, 7 - 150, 2 - 410, 4 - 410, 6 - 410, 8 - 410
I feel safe to say it has a blown head gasket, but does anybody have an explanation as to why I would be losing oil pressure when I don't see water or diesel on the dipstick. The pick up does not run hot and starts right up. I'd appreciate any help. Thanks

hummm kinda sounds like injectors all but the blow by im not sure about that could be head gaskets or egged shaped bores and worn rings. the oil pressure dropping can happen from thin oil from fuel in the oil from injectors leaking into the crank case.
a few more things id like to ask what does the smoke smell like?
how fast does it make oil?
how fast is it losing water and is it leaking out or burning it?
