I have a 83 bronco that I just got. When it runs I have a whitish smoke streaming out also I checked the tail pipe and it has black oil which seems fresh. Ther is no coolant in the oil or vise versa. I also see a slight dripping of oil where the exhaust bolts to the manifold. What does it sound like need to be repaired ?

Whie smoke means a coolant leak in the firing chamber. The oil is probably secondary to the coolant leak in the cyls. Pull all the plugs and turn the engine over( Coil wire out) and see if there is any water coming out of the plug holes. Get back with me.

Suggested Repair

Remove all spark plugs and crank the engine with the coil wire disconnected to check for water coming from the plug holes. White smoke points to coolant entering the combustion chambers; oil in the exhaust may be secondary to that leak.

Conversation Summary

The owner of a 1983 Ford Bronco reports white smoke, fresh black oil in the tailpipe, and a slight oil drip at the exhaust-to-manifold bolts, with no coolant mixed into the oil. The expert says white smoke indicates coolant leaking into the firing chambers and recommends pulling the plugs and cranking the engine with the coil wire removed to look for water from the plug holes.
