Question
The car is throwin blueish black smoke and smells alot like gas but when i get it on the road it clears and drives just fine Is the engine about to give out or what can it be?
Without personally performing some diagnostic testing, I would look into a most likely leaking of some of the fuel injectors which is thinning out your engine oil thus the blue/black smoke.
Remove ALL the fuel injectors and have them tested for leakage.
