check the piston on the EBPV on the pedestal. mine had a similar leak and it was oil going past the diaphgram in there.

psd

if you got oil in the valley.it should be coming from hpop gasket or fittings.the o-rings get old and leak.just get a rag and wipe where all the fittings are and then start truck and feel where the fitting is leaking.under pressure that oil will come out fast and may spray,watch eye
if its more in the back of valley,it your turbo O-rings?

I had oil dripping from the dust shield on the tranny, looked like a rear main leak, however it was the HPOP lines coming out from the HPOP. One fitting was loose, just had to tighten it and was thankful thats all it needed. I had a lot of oil puddled in the front of the valley behind HPOP and under the fuel filter.

I think my truck is doing the same.Did you change EBPV or did you change the pedestal.

i gutted the EBPV and pulled the piston and diaphram out. threaded that hole and plugged it, so now the oil just cycles through that chamber. next time i pull the turbo i plan on swapping the pedestal for the non-EBPV.

I think the oring you used could be the problem. I have changed mine twice, and was told to use OE because of their location.
