Do I need to change the oil pump

Hi I'm new to this site and I have a 1994 Chevy Camaro z28 with about 168,000 miles on it. When the car is at an idle the oil pressure is fine but when I give it gas the oil pressure drops, does the oil pump need to be changed?

Re: Do I need to change the oil pump

Can you give some numbers (idle, cruising, what RPM)? Chances are it is from bearing wear and not the oil pump.

^^^^^

oil pump itself rarely fails. The oil pump drive gear has been know to strip. Typically because the top part that is bolted to the block (plastic) breaks/cracks raising the drive gear off the cam and it strips. You would likely see quite a bit of metal shavings I oil though

bearing wear is the most typical reason for low/none oil pressure...
