Oil Leak I'd say it's bad! *PIX* & also fuel gauge problem

so I've been noticing a slight drip here and there, no biggie, then after I installed a 3" downpipe and open intake (it probably had nothing to do with it) the drip got worse, its dripping from between the motor and tranny, I did a search and saw that the rear main seals on powerstokes are rare, but mine is a 94 with 187k on it, there is no real specific details on common oil leaks on OBS trucks... any help would be appreciated.....

here's my driveway I washed and degreased on Saturday, and didnt drive my truck at all yesterday

I'm sure this isn't good


I also did a search for fuel gauge problems with the OBS trucks, and nothing what i was really looking for popped up, my front tank is not reading on the gauge but the rear is reading fine.... I have heard it's the switch but I thought it would be the fuel sender, I remember having this same problem on an OBS gasser that i had before... and im pretty sure this may be another common problem, any help there too would be good

I don't know OBS trucks but I would start looking in the valley of the motor for HPOP line or turbo pedastal orings.IF those all check good then it is possible rear main.

I don't know nothing about the fuel pump system on OBS.

Yep...begin by looking on top of the motor to see if the valley is full of oil. Whats making it to the ground might be the overspill. If the valley is full, look at oil galley plugs, hpop lines and seals, etc.

If the tanks are anything like what was on my '87 F150...when my front tank gauge began to get flakey...the entire sending unit that drops into the tank had to be replaced.

If there's oil in the back of the valley, (get up there with a flashlight and look!) then it's likely the turbo pedestal O-rings.

If it's more in the front part of the valley it's probably hpop line Orings.

any specific place? the valley has no fresh oil.... just dirt, grime, and a few drops of diesel sitting there

Ahhhh............what a large oil leak you have!!!:

I had a leak like that once. Mine ended up being the plugs (about 2" round) in the ends of the heads.

There is a plug at the front of head, at the end of the high pressure oil rail, and one in the rear of the head, at the other end of the high pressure oil rail.

Now there are two plugs on EACH head!

I got replacement parts from an International dealer. I think the part number is 1827535C94 (Ford or International). I think each plug for me was near $40!

The plug is basically a large pipe plug, with an o-ring on it.

I also heard of folks just replacing the o-rings, which is much cheaper. I think the FORD o-ring number is #4C3Z6026CA.

But definitely check the front and rear, of each head, for the leaks!!

Good luck!!:Thumbup:
