I would like to see your car leak out smoke to tell you what s wrong with it
blue smoke if you wore down the rings or valves,
white smoke if you cracked the block or blew a head gasket etc. you should be able to take it to a mechanic and have him diagnose the car to find the problem. a charge of course.
you will do this to your engine quickly if you overrev it constantly etc. Normal hard driving will take a while for this to happen, 1-2,000 miles
So you would have to have an engine overhaul. You should be able to choose rings, pistons, rods or even an aluminum block if you got the credits
Same thing with transmission etc
