1991 Nissan 300ZX Repair Question
How do i fix a oil leak that i cant find where its coming from.when the oil leak began there was alot of black smoke coming from the exhaust
Black smoke usually indicates a rich fuel mixture. As far as the oil leak, you can get a dye to add to the oil. Drive the vehicle and then check for the leak with a black light. The dye will glow.

easy enough to see a leak off a manifold, try placing cardboard under the engine area so the drippings will probably show. The black light system does work on small crack leaks like on a transmission case or a cracked engine block, good luck.
