"This is anupdate of my previous post. I had overheated my engine end of last season and found water in the oil. I finally was able to to remove the head to replace the head gasket. There was a little rust around the rocker arm assembly but the cylinder walls look fine. The gasket appears to be OK although I will now of course replace it, no warping of the head and as far as I can see there are no cracks in the block. I am not sure what caused water to get into the oil, other than the possibility of back siphoning thru the exhaust. This is the second time I have found water in the oil. Changed the oil and filters several times the first time it happened. Anyone have any idea what might have caused this? I hav read about installing an a anti-siphone valve in the exhaust but can't find a store that has one. Boaters World sells a "vented loop pipe" but I have read you should also install the anti-siphon (check valve.) Any suggestions appreciated."
