Oil leak near radiator?

I recently purchased a 2000 F-350 Super Duty SUper Cab 4x4, ZF 6-Speed. 110K on the odometer. The day I picked it up I noticed some oil on the oil pan, bell housing. I thought it might be the oil pan or something above dripping down. After further inspection this morning I noticed that parts directly under the intercooler tube (passanger side) where it meets the intercooler had oil on it. It looks like it might be coming from the intercooler tube itself or that general region. I plan on taking this off to change a glow plug this week and should get a better look.

Could a seal have gone bad in the turbo itself casuing oild to be coming through the turbo? Truck seems to be running great. Oil pressure and temps are good.

Any ideas as to what this could be? Once I tear into it I will let everyone know what I find.

Thanks,
MG

Do a search for ccv mod but basically because Ford reroutes crankcase ventilation back into the intake tube before the turbo, you will notice oil in the intercooler pipes and intercooler.

It looks like it might be coming from the intercooler tube itself or that general region. As mentioned, check out the CCV mod. Probably where the oil is coming from.

Oil pressure and temps are good. What gauges are you using?

I probably will go ahead and get the other 3 gp's for that side.

I am using the factory gauges as my reference.

Thanks guys!

I'd replace the wiring harness under there for the heck of it since you're in there.
Use Beru (Motorcraft) GPs.
Factory gauges mean nothing. Basically on/off.

Are you shure it's oil? Could be a tranny line

It's oil. Tranny connections to radiator are clean.

The oil is coming out of the intercooler tubes. I am sure it is the CCV thing.

Good news is all my gaskets and seals are good!

Thanks everyone!
