Check oil light on 1996 chevy cavalier. guy who sold me said that it was easy fix if i bought the part. but the check oil light keeps coming on and off. there is a rattling noise in the back so im not sure if the car will go down on me anytime soon. is there something wrong with my car? i paid $2000 for it i want to know if its worth my money since i already put $1200 down.

My question is that if it was an easy fix why didn't he fix it? I would put a manual oil pressure gauge on the engine to check the oil pressure. When an oil light comes on that is not good. It may just have a bad oil pressure sending unit but I would confirm that with a manual gauge which you can buy at any parts store for pretty cheap. If you are hearing rattling noises from the engine I would suspect internal engine problems especially if you don't have good oil pressure. Is the oil up to the correct level? It may be something little but I would want to know what my oil pressure is and if it's not good I would try to take the car back and demand my money back because that car is not worth $2000 if it needs major work. Good luck.
