Low oil presure 20 30 lbs.

Last week i collapsed an oil filter the oil dropped to 20 -30 lbs 15psi @ 1200 & 30 @ 3,000 . I changed the filter and all was good. A week later and its back but the filters ok . I changed the filter, oil pump,-10 line frim miloden pump to pick-up , dropped the pan and cleaned and checked p/u .their was some debrie in the pan but i think its from when i had a valve spring break and chewed up the valve guide . ran a diiferent oil line and oil gauge no change.All the rods look good Any idea's

Remove and check the bypass valve in the pump cover, it should slide in and out by turning the cover up ad down. The valve and spring are mounted at the rear of the cover It is not uncommon for that to happen, especially after someting breaks like a valve spring Let us know what you find

did that also , when i bought the new pump i pulled the old check valve and spring and put the new ones in. the old by-pass slid right out . thanks for the input any other idea's

Did the gauge get damaged? Maybe try a different gauge. Mopar oil pumps are pretty simple. It's usually the bypass that causes grief. It takes a lot to mess up the rotors so bad that the pressure drop significantly.

Pick up tube blocked, cracked or loose?
