I have a 2003 15hp 4 stroke mercury outboard engine and oil came out of my carburetor i looked for a pcv valve and did not see one so I don't think my engine has one and I did a compression test and had 120-125 psi
could this indicate blow by on my piston rings and be the reason for oil coming...
I took my boat out fishing and it ran just fine and the next week it started leaking oil through the carb and wouldn't start good unless throttle was up all the way what could be the cause of this?
