Ok, this has me stumped....

Friday I started diagnosing something that happened about a Month ago on the Jimmy that make me push it back in the garage. It swelled the oil filter off the truck and spewed out 3 quarts of oil. I typically crank it every week to make sure it still runs and I was going to pull it out and actually finish putting the interior in. It moved 10 feet and when I parked it, oil was running out the garage, all of 3 quarts worth.

Friday night I pulled the filter and discovered it was swollen out and the seal was blown out. Thinking simple solution, I put a new filter on and after looking things over I put in the oil spun it over a couple time while my brother was watching the underside and once I felt comfortable I cranked it. Not 5 seconds after I released the key oil starts blowing everywhere. Upon second investigation, we have another swelled oil filter and about a quart of oil all over the place. Upon this adventure I pull valve cover to see if any oil is up there, there is, but.... So, I pull the oil pressure switch and the distributor put another filter on there and run the pump with a prime tool. A geyser of oil spews out of the oil pressure tap, so I put it back in. Oil is getting to at least the top of the motor before getting to the oil passages for the main and cam feeds. So, I call it a night.

Sunday: Pull the oil filter off, (apparently still under pressure since I twisted it on my hand and can't get it off now. Drop the previously fabricated crappy Y pipe, pull the pan and drop the oil pump and pan. Crap in all in the bottom of the oil pan. Keeping in mind this motor probably has less than 1000 miles since I rebuilt it, it appears to have over 100,000 miles on it. I pull the pump apart and everything looks ok. So, anyone got any diagnosis on this thing before I have to yank it out. This seriously has me stumped.
