Bought a 2002 Exploder 4.6l for a 4 x4 go to work car as my place of employment doesn't recognize level 3 snow emergencies. We have had a couple in the past and she currently has an 03 and they are nice driving trucks.
Anyways, I was randomly getting the oil press light at warm idle. Checked with a real gauge and starts out at 60 cold. Within a couple minutes down to 40 and after a run around the block about 7ish at idle. 140k on engine.
I pulled the pan thinking the oil pickup might be plugged or maybe the pressure relief on the oil pump stuck open, but struck out on both counts.
I did find some metal in the bottom of the pan. It sticks to a magnet so its not bearing material. I believe it has had some timing chain work in the past so possibly remnants from that?

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
