7.3 High pressure oil pump
 

I have a 2002 f250, I am working on the 3rd pump in 109,000 miles. Is that normal? Is there anything that can be done to make it last longer? These have all been installed by the dealership.

What is going bad on them or are they telling you they are going bad? I just had to replace my lines and o-rings.

It keeps leaking oil all over. Did you do it yourself? How hard was it.

They may be F'ing you. If it is the o-rings they are about $13 and take about 1 hr in toll to change them all. What happened to mine once, and thanks to Doc Holiday and a couple others on this site, they pointed me in the direction of the pump and a bolt on the back. Well it loosens up sometimes and all you need to do is tighten it up and all is well. But yes I did change the lines and o-rings myself.

Type in HPOP over on thedieselgarage.com or dieselstop.com

TONS of reading on this, but the HPOP on 7.3's isn't really a notorious problem area such that you should have been through 3 of them....

Turbo Pedestal?
 

Are you sure it's not the turbo pedestal leaking? More of a common problem, maybe being misdiagnosed?

What do I look for and what do I do? Any info is wanted?

Mine started to leak on an 02 model also around 60k miles.

I took it to the dealer and they replaced the o-rings and had me going for about $130.00. I have learned since that it is a pretty easy fix and of course the o-rings are cheap.

Go to www.thedieselstop.com and you should find all the information you need.

But to answer your question to have that happen three times in 109k miles is too frequent. I have heard of dealers ripping folks off charging for a new pump with all you need is o-rings.

Hopefully you can find the cause and get better service.

Good luck

Get a flashlight and give a good look around the base of the turbo. Not saying this is the culprit but it may be good to rule out. Plenty of info on the web about fixing it.
