Hi there, is this high up on the engine? If so check the rocker cover gasket, start here.

Hi there,

OK, so is the oil at the back of the head or dripping from the bell housing, is there wet oil on top of the bell housing? You may have to steam clean down and check with a mirror and a torch for any fresh leaks after a run.

Hi there,

can't find a rear view of the head, and this engine is not in the Mitchell 1 data base, so if the rocker cover is ok, is there a cam plug? If not I would say the back of the head gasket is leaking.
