Please help!!! I just recently bought a rebuilt 350 chevy for my boat. The boat year is a 1979. Here is my only problem:
Motor starts right up and runs good. I run for about 10 minutes and by then the oil is completely milky. I have never taken this new motor on the lake and have only run it on the muffs. It has new exhaust manifolds, but didnt replace the risers. Could that much water be coming into the motor from a bad riser? Or do I have a bad rebuilt engine? Also could it be leaking from the intake? I am so frustrated considering this is a rebuilt motor and having issues like this. I just have a hard time believing that so much water could be leaking back into the motor bacause of the riser. And how do I know if it is leaking via the intake manifold. Its just hard to believe because it does run very good except for water getting into the oil. Any suggestions? Also the reason I replaced the old motor was this very same reason and thought it was cracked block. So what else could it be?
