Q: Oil pump replacement?
Hi. My PJ #458 is showing low oil pressure at idle once the oil comes up to temp. When started, it's around 75 then settles to 50 at 70mph/2000rpm while driving. Once the oil is around 175 degrees and I come to a stop light, the pressure drops to darn near zero. When I get back on the gas, it goes right back up to 40-50. I was thinking about changing out the oil pump but I'm not certain if it's a normal Ford unit or something more high performance? Any help would be appreciated.

I believe the oil pump is the original ford unit, is it reading low on both gauges.
I would be checking the oil pressure switch first or putting a mechanical gauge on it to check exact pressure. Tony

Put a mechanical gauge on it.
Let the car warm up and see what hot idle is. Oil pumps usually work or don't. So even if you changed it, I don't think the results will be any different.

Thanks to both of you who replied. I will try the mechanical gauge first and go from there. Much appreciated.

What oil thickness are you running and what brand? I dont think this is your only problem but its worth knowing.

I run 10w40 in mine. I have a stroked (302) s/c 3v. I believe that was the recommended weight oil from Saleen in the owners manual supplement for the 302 "Extreme" cars.
OP... How many miles are on your engine? Sent from my SM-G965U using Tapatalk
