Hoping someone can help me,
I have an '02 F250 7.3 Powerstroke with an oil leak. It appears the oil is coming from a weep hole hole on the passenger side of the block near the starter. I have spoke with a local diesel mechanic and he indicated it was likely due to some O-rings for high pressure oil lines on the top of the block near the fule filter. Apparently, they are leaking and the oil is running along the valley at the top of the block and draining off through a weep hole that daylights near the starter. The truck just rolled 26,000 miles and is in mint condition (yes, I baby it) and has never pulled nothing more than a single axle trailer with a few quads or snowmobiles. Does the diagnosos sound reasonable? If so, anyone have any idea on difficulty in replacing o-rings and time required?
Thanks for the help...,
Have you looked in the valley where he told you? Is there OIL in there? If so, clean it thoroughly with brake parts cleaner and gunk, hose it out with low pressure garden hose. Then run the truck, looking for the leak. Depending on where it leaks at, depends on the difficulty of the repair. If it is just one of the hoses on the side, they are easy enough to fix, if it's the plug on the bottom of the HPOP, that is more difficult.

I think your mechanic is right on. Very common spot for leaks. Do what Jim said, clean it up good on top and check for oil to re-accumulate. Here's a write up on the o-ring fix to give you a visual:
Thanks for the read Ponyboychris. I need to drive the truck approximately 10 miles to have it repaired (I really do not have the facilites or know how at home). Do you think I will be OK. I drove about 4 miles before I noticed the leak and the underneath of the truck was pretty wet. Any thoughts?
Thanks again...,
Heck, after looking at the great write up with pictures, I think I can save myself a couple hundred dollars I would otherwise spend for the mechanic at the stealership and just do it myself. Doesn't look too involved.
A good diesel shop should charge one hour labor,plus parts.
The parts are three o-rings and you will most likely be charged $30 for them.
Just had it done and it was worth the price.
A good shop will clean up all the oil spilled on the engine.
NOTE: If the leak is the pump and not the o-rings $$$$$$$$$$$$$$.

These pumps very very seldom fail, they are one of the most DEPENDABLE parts of these motors. They may not keep up with the demands of a "Chipped" motor well, but they don't break.

Seems the o-rings aren't, by the number of posts about leaks.
However, thanks to this forum I found the leak in no time at all.
If you ever need Diesel work and your are close to Paso Robles, CA then North Coast Diesel is the spot.

Hi Jim,
Do you or anyone know a good diesel mechanic in the St Louis area? I have a friend with a '95 OBS Powerstroke and he needs some head work (hopefully that's all) after having discovered he bent two push rods and broke a rocker arm. He wasn't over revving it, they just broke.....motor has approximately 200,000 miles on it. Thanks Les

By the time a Tech cleans up the engine, puts some dye in the oil, test runs it to make sure there is ONLY ONE LEAK he will have more than one hour in it. Probably 2 hours in it maybe 3 hours total by the time he changes the o-rings. Plan on it costing 300 to 350 bucks at most dealerships.

1999 7.3 power stroke leaking oil out of weep hole
I recently got a 1999 F-250 7.3L power stroke with 186,000 miles on it. Didn't notice until today that it is dripping oil out of a weep hole in the bottom of the engine. Don't know much about diesels but trying to learn. Any advice?
