I took my car for a spin over the weekend and as soon as I stepped on it the oil light came on. I turned the car off right away hopeing that doesnt hurt the turbo, but more worried about the motor. i got the car home and call a friend of mine that had an oil gauge not installed yet. after convincing him to let me hook it up, the pos plastic tube didnt even get a drop of oil in it when i started the car. I did notice the car squelled, kinda of like the alternater belt was slipping. thats what i thought it was. Could this be anything other then the oil pump went out, and would an aftermarket crank pully cause it to go out?
