Hey everyone I recently bought a 95 T100 with a suspected head gasket issue. I pressure tested all the cylinders and cylinder 1 has 60 psi compared to the 150 in all the others. There's also oil in the coolant reservoir. I have torn everything down and have the heads off there is no signs of cracks in the head. I think it is just the gasket. Wanted to know what some of y'all thoughts are. I might chance it and but a new head gasket in and put everything back together. Would you guys machine the heads and have the vales redone?
 
The standard approach, I believe, is to have the heads magnafluxed and decked and probably a valve job while they’re out

It would suck to do all the work and put it back together to find you still have problems.. something you missed
