Hello
First off I'm used to working on outboards but no experience working on diesels.
My nephew bought a boat and when I went down with him to check the fluids today 1 of the engines had a oil in the tank on the top of engine where the coolant get replaced.
Iv'e done alittle searching around but can't pin point posts about the 6-71 and firgured I'd come here.
Iv'e seen a few posts saying that it could be head gasket , oil cooler leak , cracked head/cylinders. What else whould I check that could give the engine these symptoms? Wouldn't a compression test eliminate a head gasket or cracked heads/cylinders? If so what PSI should each cylinder be?
The previous owner said that he recently replaced a gasket that fit between the engine block and the cooler and that it was pressure tested and held about 50lbs. He 'thinks' it could be either the gasket blew out again or old oil left in the system when the first oil cooler gasket blew out, that wasn't totally cleaned out.
Thanks,
DamianJP
