"El I appologise for heading straight to you on this one but i been reading up on the old posts and you appear to be the authority here...

You have a good idea on what I have been through in replacing the exhaust elbows, manifolds off, new gaskets, drilling / spark eroding bolts out ect. This week I did the timing, mixture and idle speed only to find out that Ive now got milky oil in the starboard engine. Water appears to be getting into the oil. I have a suspicion that I may have done this myself by fitting a fresh water hose direct into the pipe between the filter and impeller because the impeller wasnt strong enough to pull the water in from the tank I have the leg sat in while im out of the water. Sounds a bit strange but the water system was full of air so feeding a direct hose line seemed a better idea to flush out any air bubbles. I feel that the continued water pressure from a tap fed hose into the pipe as i stated above has forced water into the oil via maybe the manifold or head gasket. Apart from the obvious washing out of milky oil what do you think my best option is to find out where the water is migrating from ??? Head gasket or manifold ? Or should i simply wash through and run for time direct from the tank and see if the new oil goes milky ? Help."

"Hi,

Before panicking, I suggest that you change the oil and filter (after running the engine for a few minutes) a couple of times, so that you can flush any water you may have left in the crankcase (you can use cheap oil and filters for that purpose). If, as you think, you put the water in yourself, the oil won't turn milky anymore and then you are fine. But if the oil turns milky again, then it would be the time to find the source of water ingress, which amongst other things could be due to a faulty head gasket, a faulty exhaust manifold, or (God forbids!!!) a cracked block."
