water coming out of port top left hand side of motor. what can it be..Pontiac Bonneville. 1992

Eximo

Titan
Ambassador
We do have a section for cars...

1992 hmm, possibly an external head gasket leak, vs when it leaks into the cylinders producing huge amounts of white smoke out the exhaust. Bad water pump seal perhaps. Can't imagine anything that would actually cause water to leak out of the intake manifold.

Depending on what "port" hes talking about, it could always be the water pump weep hole leaking indicating a failed bearing/seal in the pump.
