18R-GU motor. This all started last week when i took off the intake manifold to fix an oil leak, why does the head have those three square holes that water comes out when the intake manifold comes off. Anyway i put it back on with a new gasket using grease to help seal it but later finding out gasket goo should be used, drove it then notice water coming out exhaust and checked oil to find it milky, i took it off, found water sitting in port 4, so on again with another new gasket using gasket goo and now its still leaking into port 4 but not sptting out exhaust and not dirtying oil, the manifold looks straight, i cant see why its leaking coz it didnt leak before?
