I've got a Yanmar2GM. Oil is coming out of my exhaust, I thought it might have been carbon... but it seems like a lot of oil, and because I am in a busy harbor, I am hesitant to keep running the engine to see if it goes away (oil slick leading back to my boat, not great). Engine is running fine, good water flow... no black smoke, but it is spitting something, leaving an unpleasant, rainbow-like (not certain that is the best way to describe it, but oh well) pattern on the water.
Problem started after I did work on my mixing elbow. Two bolts out of 3 were rusted into the engine body. I had to drill them out. Elbow wasn't damage, not too much build-up either. I was able to re-thread the holes, and to put the elbow back on, but now I've got the oil issue. I did spend a lot of time drilling into the side of the engine, I wonder if I just dislodged something in there, or maybe it's the head gasket? Anyway, I'm at a loss here. I fixed a thing, then messed something else up it seems... engine was running fine before I discovered the elbow bolt problem.
Cheers, help? :/
