Either blew the head gasket or had back siphoning. I did over heat the engne by forgetting to open the raw water inlet at the end of last season. I tried to remove as much water as possible by changing the oil several times. Could not find a mechanic willing to work on it (there're like Gods around here)so it sat all winter. I can see rust around the rocker arm assemly when I remove the oil cap. If I have the head gasket replaced what issues will I have with the rust and what should be done to alleviate it. Any help greatly appreciated. Thanks |

I had water in my MD11C crankcase. It was caused by my leaving the water inlet hose in a bucket of fresh water when I was preparing the boat for spring launch. The bucket was above the engine so that the water would siphon back into the engine when I would shut it down and leave it over night. I changed the oil and filter several times and it seems fine now. |

I made another post but do not see it here. Basically I would like to know what problems if any, may arise with rust inside the engine and what my options would be.
Thanks |

you probly have rust thr out the engine,if when you remove cyl head there is rust on cyl walls then unit needs to come out for o/h. if no rust then remove oil pan to check for rust on crankshaft, if none then you mit be able to get buy with cyl head o/h. |

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. Any suggestions appreciated. |
