oil leak....main seal?

So I went to a dealer for a free check on an oil leak. Everything was normal, I was towing 12k gross, and that night there was prob. about 6 spots dripping on the ground, 3-5" dia. marks from oil. I thought it had something to do w/ the turbo, ped, or EBPV stuff. There is no oil in the valley. Oil is all the way back to the tran. pan, exh. pipe, and the cross member. Take it to the dealer and they tell me, my main seal is leaking, along w/ my oil pan, oil cooler, and crankcase....something basically saying 2800 for a repair. I even asked about the turbo and the tech said it was fine, dry. I took a mirror to look behind the turbo and I see oil dripping off the ebpv rod, and fresher/wetter oil all around the back of the turbo.
How much oil can leak from the EBPV?
Is there any way I can check to see if the main is leaking?
Over all the leak is about....1/2 gal 3-400 miles

I thought something was wrong w/ the turbo, so I switched my chip into a higher setting and under heavy load when the boost hits 9-10 psi, the turbo makes a very subtle high pitch whining type noise. Easiest way to describe is like an elec. motor at a very high pitch, high speed.

Sounds to me like the turbo pedistal is leaking and not supplying enough oil to the turbo. You probably have already fried turbo and all the oil that is suposed to go to turbo is all over the back of the motor.

It is very doubtful that your rear main is leaking. It is possible but VERY uncommon.

Chances are that the oil is coming from the pedestal and/or EBPV piston. Best thing to do is to get everything cleaned up as good as possible with simple green and garden hose pressure water.

Next, you have 3 choices:
1. Gut the EBPV from the pedestal,
2. Rebuild the pedestal EBPV with a Garrett kit
3. Replace the EBPv pedestal with a non-EBPV pedestal.

Any of the above will cost less than $200 if you DIY.

Oil cooler can be rebuilt if you find it to be leaking after you fix the pedestal. This is also an inexpensive DIY repair but usually an oil cooler leak will get oil in the coolant.

It sounds to me that your dealer is looking for suckers that they can take to the cleaners to improve their bottom line. Kind of reminds me of the old full-service gas stations where the attendants carried around an ice-pick in their back pocket. "Sorry sir, but when I was checking your water level, I noticed that you have a leak in your radiator and we can replace that!"

The apt. complex I live at doesn't have any outdoor faucets, and only thing near by is a car wash. I just bought the simple green and tried to clean some of it, but to me it seems it has to be turbo related. I've been shopping/looking at ways to disable the EBPV, and I probably will be doing that. I ordered a turbo re-install kit from ford for $25, which has the bolts and alot of o-rings. Will be getting ped. o-rings also. Anything else I would need. Thinking of doing a WW install too. Is there any thing I need for that. All I can think of is some more PB blaster. Any "special" tools?

I couldn't believe what the dealer said, I even told them, it was odd the most expensive things to go wrong on the truck all went at the same time. The service mgr just laughed.
