Ok but where is the oil pump?
The blame for Jr’s engine failure from DEI is the belt broke because of track debris????
Nascar uses what's called a dry sump oil system, no oil pan. The pump is belt driven and (I think) located back by the rear end. Hoses supply the oil up to and from the engine.
Will try and confirm.
It may be located up front, sort of like the a/c on your car, but either way, the belt can break or get dislodged by a pile of marbles being flipped up or any other piece of track garbage for that matter.
