RE: Low FE428 Oil Pressure...Help

Thanks for your input RC...the relief spring seems to have a pressure bewteen an stock pump and a high pressure pump when I compare them, so I think that it is OK.

Oil Pressure gauge is a Borden Tube typ and I checked it with my air compressor. Every regualtor change fro 10 psi to 80 psi...both gauges read the same.

You very well be correct in your thoughts it doesn't take much of a leak to reduce oil pressure. Maybe this is what confuses me. We all know these Fords require higher oil pressure than Chev's, right? Well...why is that. All bearings for rods and mains require the same lunrication regardless of what manufacturer they are originate from. So...it is the smaller oil galleries in the Ford that make the pressure high right after the pump...but the same as a Chev at the bearings...I have a hard time getting over this fact. The galleries themselves contribute highly to back pressure and subsequently the oil gauge reading shouldn't change much form even a spun bearing.

Hey, withthe old HP/HV pump I had 145 psi..now, with the HV pump only I have 58psi.....teh relief valve isn;t even opening anymore...but still no debris in filter.

I was using a Fram HP-1 and 10W40...I also use a System 1 oil filter now and then...just install a HP-1 between using the System 1 so i have time to clean it.

I used to use 10W30 when I had the HV/HP pump.

The HP pump could actaully suck the sump dry with cold oil that wouldn't drain back properly. If I moved the car to quickly after starting, you caould see the oil pressure gauge flicker as the pick-up got an air bubble.

I love my car...and I think the engine is terific, but I know something is wrong, and I don't want to lose a 428 crank...or any other expensive parts because I didn't listen to what the gauge is telling me.

thanks a lot for your input.

John
