hey everyone,
i was just wondering...

a good friend of mine sold me his 1979 450sl a while back and i haven't had alot of time to work on it until recently. the car drives with what i hope to be some minor problems including:

-when i start it up and drive it, everthing seems fine, but when the engine warms up and its idling(stop sign or traffic light) the oil pressure drops, engine idles at very low rpm, and usually engine stalls, but once i accelerate the pressure goes back up. (to help it to not stall when im at a stop light, i switch into neutral and rev the engine a little to keep it just below 10)

-engine seems to run very hot. im scared it will overheat

-when i start the engine after it has cooled down, ALOT of exhaust smoke comes out of the exhaust pipe. when the engine warms up then not as much smoke comes out.

if i could get an answer to some of these problems it would be great. thanks guys!
