Purchased a AC Delco Oil Filter PF47E. I installed it on my 2000 Chevy Astro. I noticed my engine did not have much oil pressure on startupand heard a rattling in engine. I drove it for awhile thinking it would clear up and it got worse. I went ahead and checked the oil it was fullbut was very dirty. I went to change the oil and the filter would not come off. I had to literally chisel it off. It was as if it had sucked in a vacuum on itself. The inside of the filter looks totally disintegrated. I have since heard some complaints from others on these filters what gives? Plus my engine noise is still there.
