I was driving along at around 60mph in my 1996 blazer 4.3 4x4 with
114.000mi and all of a sudden i could smell something hot, i noticed there was almost no oil pressure. So i pulled over and shut the motor off, but not before i heard a rattling sound from the motor. I motor will still start and it sounds ok at idle but as soon as i step on the gas i hear the noise again. Anyone have an idea. Thank you
