there was and is stll oil (new stuff) so got it back up on ramp to have a look and all be it its NOT AS BAD as it was but is still all over the place , looks as if its coming from roundabout flywheel area near the sump if u no what i mean been told its maybe crankshaft seals but why is it not as BAD as it was ? are these sump gaskets dodgy ? or is it known for crankshaft seals to PISH oil everwhere under LOAD any help really really apreciated as im about to drive the car of the harbour
