So I drained the crank case. About 1.5 gallons of crystal clear water and 6oz of milky oil. Engine turns ok and there was no rusty water in the crank case. What’s the idea?
So I just bought a boat (wicked cheap) with a 3.0 OMC which from what I found is the same as a merc. The oil is way over full, halfway up the dipstick, of milky oil. Smells almost like gas. Supposedly boat was ran 2 years ago. Are we sure the block is cracked or can this be a head/manifold...
