well its the main bearing that is spun. what happened was i was selling the car with a bad headgasket ( which now that that i think about it is also bad but, when you do the bottom end you should do the top anyway) but still driveable, so i was taking it around the corner to vac. out the car but when i got to the stop sign the car stauled i was thinking (well that hasnt happened in a while) but when i tried to start it back up it wouldnt start it was just like the battery was going dead ya know the motor barrely turning over. so i took out the battery tried to charge it but it was already charged. so i took the wheel off hooked a beaker bar up to the main pulley ( after taking out thye spark plugs) and it felt like a spun bearing so thats what im going off of.
