1995 7.3 oil leak

[Sparchuleta]

Hello. I bought my first deisel about a year ago it is a 1995 7.3 it has 171,000 on it and it has an oil leak somewhere I can't seem to track down ? I can drive it for about 100 miles or so and it's usually 2 qrts low I just replaced the rear main . I have kept an eye on the hpop and the top of the Gally and there is no puddles building up but after driving it and inspecting it I have a oil drip coming off of the right side of my bell housing but it is not a constant drip it's just wet ? It's got me stumped I don't know where it's loosing 2qrts from a slow drip ? Unless it's burning it. If you guys have any suggestions it would be greatly appreciated

If it's loosing that much that quicky, it's gotta be going somewhere else. The first thing that comes to my mind is injector o-rings. What does the fuel filter look like? Is it really dark/black or have a slimy-ish look?

I'm not sure I have not pulled the fuel filter since I have had it?.

How long have you had it? I would recommend checking it... I change mine roughly every 10k. It's probably overkill, but I don't really care!

What does that mean if it is dark/ black or look slimy

[Sparchuleta]

Iv had it almost a year and since iv had it iv put maybe about 1000 miles on it . Iv been working on it trying to fix all the little problems and nick nacks . Iv just recently replaced the rear main because it looked like it was leaking but when I got to it it was not leaking

If it's real dark it may just mean it hasn't been changed in a long time, but from what I've read (never dealt with leaking injector o-rings), a black/slimy filter indicates oil in your fuel, from leaking injector o-rings.

Your injector orings can start to wear, high pressure oil will be forced into your fuel rail. The oil will than feed back into the fuel tank from the return line from your engine. Than the oil than jus went into the tank and mixed with fuel will than be pumped back to the motor and you will be running oily fuel- making your filter black.

Pull your filter and look at fuel in bottom of fuel bowl, is it clear or dirty(from oil)

Another thing to do is stuck a 3/8" or 1/2" hose in your tank and suck some fuel out, does it look dark? If so injector orings.

Another thing could be Turbo could be passing oil but that's seems like a lot of oil for turbo.

I learned everything I know now about the Powerstrokes from here, and from wrenching on my own truck. That's what we're here for!
