Re: Water in Oil
I have a 1985 305 Mericruiser. There is water in the oil. We think it is the risers. How do you test for leakage in risers?
Is this a running engine?
If it is, and the risers ARE in fact leaking, you would know it because right after you shut down, a little bit of water would run back into open exhaust valves on both sides.
Then, when you cranked it, it would hydrolock a "little".
It would eventually start because that little bit of water would be pushed by the rings. Then, while subsequently running the engine, most or all of that water would evaporate out.
If you have a LOT of water in the oil. I.E. the oil level has increased measurably, then you have a crack somewhere in the block, heads, intake manifold, etc....
You DO NOT get a LOT of water into the oil from leaking risers.....mainly because it doesn't leak into the engine while it's running. And it's not very much either.
