The oil leak has been addressed by applying a SILICONE BEAD around the oil and coolant passages on the head gasket. If the head is FLAT, have a clean-up cut done on it. BETTER YET . . . If you have a machine shop in your area that surfaces heads with a belt sander . . . do that . . . If the car doesn't smoke at start-up and the COMPRESSION, POWER and IDLE are OK . . . you can get away with just doing a HEAD GASKET . . .
