:confused:hi any suggestions on why grey oil, and really thick ! engine ran great for the last year, run on monday,tuesday and wednesday no problem then on thursday grey oil started to flow out of rocker cover and down onto the starter motor , is it the head or something else.
 
Well, if oil is flowing out the top of your engine,that means that a water level higher than that is pushing it out,which usually means a siphon from the seawater side. Unless you have a large overflow tank that is quite high.Better get that cleaned out Pronto!
 
Hello Blobbt, What is happening with the Fresh coolant water? The raw water can get in through the Exhaust system. We need more clues... If there was a crack in your oil cooler there is a chance of water going into the oil system. Have you drained the oil out yet? Keep up******....
