My friend has a 93 mustang. When he accelerates at high speeds the oil prssure will somtimes go down quite a bit Does anyone know what might cause this? He recently had some work done to it and does not want it to blow up.

Basically when he accelartes at wot and the rpm's reach 3grand or so the oil gauge goes down alot as long as the gas pedal is mashed. it seems to be fine under normal driving that is not wot

stay out of wot, get a new oil pressure sender, and hook it up to a real (a la autometer) gauge. if it is still dropping w/ new sender and good gauge, he doesnt have long left

I'll tell him to try that. Do you have any idea as to what could cause this problem?

Sounds like a cracked crankshaft. I've had 2 cars do that and both had a cracked crank, It stresses under load of WOT and oil leaks out through opening cracks.
