Yeah but the word "fix" implies there's something wrong. IMO, there's not. It won't hurt a thing to keep it just like it is........with a replaced rear main seal of course.
I agree to a point, it's not rediculously low, it's just not what it could be with that pump.
This thread is very much like the Bam lifters thread where guys keep trying to run a roller lifter without block mods and then have less than ideal oil pressure. As far as I know the only drop in roller lifter for Mopar small blocks is the comp cams.
