Re: Mercruiser 470 exhaust manifold cracked
do you mean 220 degrees . your right about how a/f can get into oil but someone told me that it could go down the exhaust into the cylinder and into the oil .that seems a long way to go ! so when i checked the riser and found a hole letting raw water into the manifold i thought maybe he's right . found those leaks i stated before and now hopefully the 2 pound drop in 35min was just the tool . oil still looks clean .what do you think ? does your engine run good now ?how hard was it to replace head gasket ?
