7.3 oil pan leak

[NatureKat]

Any help would be appreciated! My 2003 7.3 with 220k, quigley, Sportsmobile conversion, was just in the shop for routine checkup. Oil pan gasket is leaking. Our shop doesn’t have the proper lift to remove the cab from chassis, the local ford dealerships lift is down and they don’t know when parts are coming in for it to work. Our shop called all around Bend and nobody will touch it. If any of you have had a similar problem and know a great shop, please let me know. We also need a new rear main seal and our shop said to just do both at same time. Thanks for any help.

Maybe find a mechanic who is willing to try to sneak the pan out in place like that guy did?

Don't mean to question your observation. Are you aware the 7.3 is notorious for oil leaks in the upper valley and the oil drains down the back of the motor and can easily be misdiagnosed is a rear main seal or pan gasket leak.
Just thought I'd mention it.

Good to point that out Lilnuts2!

If that's the case a careful through cleaning of the engine block from the valley downward would be in order. While no where closely related the V10 & V8 Modular Motors have a head casting issue that caused an oil leak some often took as signs of a blown head gasket. Those leaks would be seen at the back of the engine on the passenger's side when the dog house was removed.

Just for grins what is the source of the oil leak coming from the upper valley on the 7.3 engines?

[REF]

A common point source would be the HPOP

Watch this video on the subject.

Did your shop check to make sure the pan bolts were tight?

260k on my e350 with 7.3. HPOP was rebuilt prior to me buying the rig at 80000. I’ve had two valley leaks since then. One was passenger side high pressure line to the head. Driveway fix was challenging but successful with the replacement of a $0.10 o ring. One other minor leak was from the turbo pedestal. Two more cheap orings and I replaced the up pipes while I was at it for another $100.

Lots of degreaser in the valley and around the rear of the engine allows you to pinpoint the location of the leak.

Any drips from Fuel bowl, hpop and lines all collect in the valley and drain out the back right over the rear main and out the flex plate cover hole.

No drips on my driveway now.

Curious what became of this?
