PF141 oil Filter

Re: PF141 oil Filter

Well, okay, I've had a couple of days to think about this.

Hydraulic systems can operate from 100 to several thousand psi. I assume they have filter bypass valves, but they might open at higher differential pressure than the 10 psi valve on the Corvette.

The original PF-141 had no metal outer case, and I never heard of one ever collapsing due to excess pressure differential.

The metal outer shell will withstand higher pressure differential, but that should never be an issue on an automotive lube system, but could be an issue in some hydraulic systems.

Given the same filter media and total media area, I see no advantage in the HD filter, but, as the engineer said, it should do no harm.

Now, if you have a racing engine with a HV oil pump and the filter bypass valve is blocked and you like to rev it to 7000 immediately after a cold startup with straight SAE 50 oil...
