Any Ford 7.3 Techs Here?

I'm having a repeat issue which three diesel techs have not been able resolve. A bad oil leak from the pedestal base. It will pump out 2-3gals in 20 miles. O-rings replaced as well as a new pedestal. Any help please!

I'd say either your new orings slipped out of place or the oil is coming from somewhere else.

Pumping out a large amount of oil, it's probably coming from the high pressure pump. There is a kit that has new o rings and fittings for the high pressure lines. Usually what happens is one of the block off plugs on the HP pump backs out a bit and then the o ring fails. Anything that leaks in the valley runs to the back and can look like it's the pedestal leaking. While you have it apart, look at the fuel tubes to and from the fuel filter housing. The right hand line to the RH head can wear on the bracket to one of the intake bolts. I've seen them wear through and make a big fuel leak. There's also a kit to replace all of those fuel line seals.

Full disclosure, I don't know diddly crap about the specifics of your issue.

I agree with Farmboy and will add are they torquing the pedestal bolts?

There is a valley pan on the 7.3 diesel that CAN and many DO leak, there is a PCV system grommet in that pan that also age hardens has that been looked at? It is retained by the intake and ONE Allen head plug style fastener, they DO come loose.

There is no valley pan on any 7.3 Powerstroke, never has been. I haven't seen an indirect engine for many years now so I can't really say about them. Aside from the HP oil pump and turbo pedestal, the only other possible place oil could leak in the valley would be the lift/transfer pump used from 94 to about 96. Afterwards they used an electric pump and the hole for the lift pump is closed off with a cup plug. There is also no PCV system in the valley either. There is an oil separator on the left side valve cover only.
