A month or so ago I took the 2001 F-350 to the shop for a major oil leak. Guy said it was the o-rings for the high pressure oil lines, and supposedly replaced them. Picked the truck up and drove it home only to lose 4 quarts of oil in the 12 mile trip. (ok, I didnt really "lose" it - it was all over the passenger side and under the truck.) Had it towed BACK to his shop, had him do it "right" and everything was fine for about two weeks.
Two weeks ago I had the same problem - major oil leak again. I decided that the shop must've screwed it up so I did it my self this time. Pulled the pump (and EVERYTHING in the way of the pump), replaced EVERY O-Ring, gasket and seal - including the "non-serviceable plug".
Everything was happy happy until yesterday when the truck started blowing oil again. I looked this morning and sure enough, its leaking around the HPOP AGAIN!
I'm not sure why. I got all of the stuff I needed from Bob @ Diesel O-Rings, and put everything back together per the instructions. No oil leak for two weeks and now this? WTF??
Is there something else wrong that could be causing this problem?? I'm ready to start looking for a really tall hill next to a really deep lake.
