Found out yesterday that I used an OEM filter in an after market cap last time I changed the oil. Unaware of the difference of course. So basically I have been running unfiltered oil thru the motor for about 4000 miles. The IPR did have a bad seal, when I spray a little starting fluid into her. I Can get her to start and ICP tests good. I have zero low oil pressure on the gauge when cranking with no start but when it's running I have full low oil pressure, as soon as I let the rpm's get below 1000 it stops to zero. Do I need to pull the ENTIRE HPOS system apart and check for failure/debre or should replacing the filter and cap to its proper OEM PARTS FIX fix the problem?


Apparently you would like us to guess what year, brand and model of vehicle you are talking about.........
