Re: EF XR6 oil pump probs
If he's done all that work to the oil system, there is one simple reason - he thrashed the car. He might have done it for two purposes:
1) The oil system broke down because he thrashed it/didn't change the oil/ran it dry
2) He changed it to supply volume while he kept the motor at 6K revs.
Either way I'd be very very careful right here...
