"great forum..I hope you all can help me. 1985 mercruiser 3.0 L 140
noticed water in the oil....ran a compression check and got close to 145-150 on all cylinders. I assume therefore that I dont have a cracked block, warped head or bad head gasket. It DID overheat for a VERY short period of time the first time I had it in the water due to a bad impeller which I subsequently had replaced. After some research I figured that the milk chocolate in the oil pan was due to a bad exhaust manifold gasket caused by the over heating. I have removed the exhaust manifold and riser and have a new gasket set at the ready.....two questions...1) does anyone think I am making bad assumptions, and 2) how can I find the torque specs for the manifold bolts? I am assuming around 25, but I dont want to be too far off...also, is there a blt tightening pattern? Thanks in advance."
