Just a little oil leak?

[kalski]

I have an 02 7.3, found oil on the ground and traced it to the valley. Took it to the dealer and was told it would be $150.00. They called me and said the HPOP was failing and it would be $1600.00 +. I told them to leave it be and I would like to investigate it further.
I do see oil under the fuel filter, is it possible for this to be just a seal or fitting issue, and can it be repaired by oneself at home. Can I replace the pump myself, I am mechanically inclined but haqve never worked on this truck, or any diesel.

I don't know anything about it. But that does sound like Ford service. LOL

Sounds like your HPOP o rings are leaking, if you do it yourself its all of a 8 dollar fix for the two new o rings

Do it urself.

Hey, thanks for the replies! I cleaned the area around the fuel/water separator real good. I started the engine and gave it some revs, but did not find visable leaks on the hoses. Perhaps it is coming for the gasket/o-ring behind the pump. I believe I would like to change the pump if I have to do surgery anyway, if I can find one. Any more maintenance I might as well do while I'm in there?

Get one of the UV dye kits they are worth there weight in gold for finding oil leaks in A/C, Oil, Coolant etc

You need to get in there with a flashlight and a mirror while it is running. If there is only oil in ther rear of the valley, it is probably leaking from your o-rings on the turbo pedestal. If there is oil in the front and rear of the valley, it is most likely leaking from the o-rings at your HPO lines. Don't just replace the pump yet. It is polly OK. This is an easy fix!!

Here is a good instruction sheet for the repair....so I don't have to type it all

Here is where to order the o-ring from:

Replacement O-rings for Diesel Engines

Here are a couple pics of what you are looking for:







This is a video borrowed from Shane(sea71). Keep in mind this leak is coming from the topside and is easy to see. Mine in the past has leaked from the bottom side of the fitting. That is why the flashlight and mirror are necessary.

You can also oder the AE software and see what PSI the HPOP is putting out. If it is weak you can get the adrenaline pump from Dieselsite for $500. I have no idea where they are getting $1600. I do agree the most common areas are the O rings on the HPOP lines. I have also seen high mileage trucks drip oil from the intake boots and down into the valley. Doing the CCV mod will cure the oil in the intake.

I also have a small oil seep coming from this same area, but it is not either one of those 3 spots. is there a gasket on the front of the oil pump that could be leaking? Thanks
