If I pd. $1588 for pk head gasket, r&r cylinder head & replace leaking head gasket set & allseals and gaskets as needed. engine leaking oil?
if you paid someone to do that? take it back. If you did it yourself, you probably did it wrong, and can be a many number of things.
It could be that the oil plug was not secured properly or the oil filter was not attached correctly. It would be better if you took it back to an experienced mechanic and have all the faulty areas corrected.
