[Foley]

I had the same problem with the oil pan. It musta landed on top of a fire hydrandt at one time or another. The intake screen and pipe of the oil pump sit pretty close to the bottom of the pan and I figured it was a good idea to pull that pan and fix things, plus I wanted to look in the bottom of that pan and see what the story was. If you are talking about the 2WD, 305 V-6, I had to do the following in order to get that pan to slide out of there.

Remove the oil filter cannister, exhaust "Y" pipe, bottom flywheel cover, and then loosen the motor mounts and transmission mounts. Jack up the motor about two inches and the pan should have enough clearance to slide down and out the back. I was able to find a decent oil pan by advertising here on this site plus checking Craigs List. It was also a good time to pull the oil pump, clean and inspect it. It was pretty good except for the circular wear grooves on the bottom plate. I resurfaced that plate to get rid of those wear grooves.
