FML - Leaking around the HPOP AGAIN

[ToddOH43]

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.

Where exactly on the pump is it leaking at

At the very least its leaking around the "non-serviceable" plug (that was replaced with a "serviceable plug") as well as the lines.

The strange thing is all was well for two weeks. Truck ran fine, oil level stayed up, no leaks period. Last Thursday night I saw the stripe of oil on the street that leads to where I park the truck.

Anyone wanna buy a 2001 F350 CCSB SRW? 242K on the clock, new tranny. Small oil leak...

Well that may be something as simple as a bad o-ring I understand that's all new but I have got bad new parts before and may be something that just needs to be snugged up give the girl some TLC

I'd be inclined to agree if it hadn't already been "fixed" twice in the last six weeks (once by a shop, and once by me) only to leak again after two weeks of driving.

I'm guessing at this point I'll move it over to the other side of the shop tomorrow and tear into it again. Maybe the third time is a charm. If its three strikes and you're out, I'm going to be a little salty.

Ding, ding, ding....

Give the man a cigar. I finally broke down and took it to a shop (this time one with experience working on diesels).

The result? The o-ring on the non serviceable plug (which I replaced with a serviceable plug) had failed. He also replaced the IPR as the pressure from the pump would randomly drop during acceleration.

Seems to be fine now. Idles smoother too, but I still get a p1211 code with my Edge on #3 if I have my foot in it. Not sure what's causing that - might have something to do with the Edge as opposed to something being wrong with the truck
