3.0 omc cobra gm engine. So I found there is water in my oil. Took the engine apart and could not find a crack in the block anywhere. The exhaust manifold had some water mixture( don't know if it was fuel or oil ) in it and the gaskets looked really old at the elbow and block, but had no cracks in it. A couple weeks ago I took the outdrive off and used the same gaskets it had on it when I put it all back together. I am wondering if water could somehow get into the oil from the outdrive or if I have a bad gasket somewhere?
