Think I should clean the oil pump screen?

Just leave it unless there is cause for concern. If you have good pressure I wouldn't bother. If you need something to do on the weekend it wouldn't hurt.

HI I'm new here and I was thinking of droping the oil pain to clean up the inside of the pain and the oil pump screen. The car has 163,000 miles. The engine has a little knock only at cold start up. I changed the valve cover gaskets and the distributer gaskets and their was no varnish or sludge on any thing the enigne still looked new. I use moble 1 synthetic oil and AC Delco filters. Should I clean the pump and pain or just leave it alone. I have the 3.1L V6 LHO.
