I have an oil leak somewhere around the rear of my engine, I can't see anything from the top.

Just remember, oil will go everywhere BUT forward

I have heard there is an o-ring

The O-rings on the HPOP fittings are actually #6 O-ring boss. The ports in the head are #5. You can get them at any hydraulic shop.
If it is not the turbo pedistal, then it's the HPOP O rings. The way you describe the leak sounds like the one I had. Is it small amounts and how long has it been going on for? Is it getting worse? I couldn't see the leak until I REALLY Looked closely at the hpop, then I found it oozin out, ever so slightly but it sure is a gusher when the truck is running... here is a
picture Anyways you'll need some locktite, the Orings and a few tools. Stealership says it will take 3-4 hours @ $75.00 an hour + materials. If you go
here you can see my thread. It took from 04/06/06 12:32 PM till 04/06/06 03:38 PM to find the leak, get oil/materials needed from dealer and wal mart and change 2 of the 3 O rings that looked worn. Total 3 hours to get stuff, actual work took about 1.5 hours.
FYI - I needed 2 gallons of oil, I think a 5/8 wrench, a #47 torx at a 90 degree angle (or a straight one with a wrench to twist it b/c it becomes oily and slippery) some paper (makeshift funnel to fill HPOP res), strong battery charger, allen wrench(s), a good memory lol since you have to take apart some fuel lines so that you can crank on the Hpop fitting (lots of little springs and plastic pieces, ALOT of papertowels, and small container to pour the oil into the HPOP. Total install was like 1.5 hours but after reviewing the info, I didn't replace ONE of the O rings, but it wasn't leaking so like JimTJr said, if it ain't broke don't fix it. After you do this install, letting the fuel pump run its course (to fill the fuel filter since you d/c it and drained it) and crankin' it a few times it started!
lol it feels good to do it. ALSO FYI, there will be oil/diesel in the valley since you had the lines off... spray degreaser and blow out with water, it will ''leak'' oil for a little while, but in reality its just the excess running out of the valley down the back of the engine block and tansmission. You can tell that its just water if you get up under it though. to add to the tools used, a 12"+ needlenose does wonders precisely picking up small springs (inside all fittings) and the HPOP cap from the valley of the motor. They are so small, slippery, in tight, and of course 'springy' so you're likely to lose them if your not very careful.
