A few things could be wrong what engine/year do you have and are you noticing any driveability issues?

its a 99 3.0 vulcan. and yes when i was driving it, it sounds like it was knocking real bad but that would onlt oaccur when it was warmed up. and right after it would start to knock it would stall out and not be able to start again. then the last time it happened i was driving and it stalled out, then i looked under the car and under the hood and there was oil everywhere...
