7.3 2001 Excursion Oil leak

[Devil DOC Excursion]

I have an 01 Excursion and I'm fairly new to the diesel scene. Just some info on the truck; it has a TS performance 6 gun switch, custom CAI, 4' straight pipe, Banks down pipe and waste gait eliminator, 4:56 gears, Custom drive shaft, CCV vent mod, to name a few. The problem I'm having is that initially the shop I took it to stated that the leak came from the O rings on the pedestal. So those where replaced and still leaking. Then found out it was the EBV arm on the pedestal, so replaced the whole unit and all brand new rings all around. Still leaking but not as much. The other issue is the previous owner also has a tube like the one for the CCV vent mod coming out of the oil fill cap as well, which also has a little oil weeping out. The tech said he never saw that before. Have you guys ever seen this? Also would it hurt anything by putting a regular cover back on it? Im losing my mind over this. It has good power and drives well but the leak drives me nuts. Im also wondering if there is to much pressure in the crank case due the tune being to high maybe?? Again just looking for HELP

pics of the cover?

A tune shouldn't be able to put pressure into the crank case. The cap would just be another case vent. Maybe the po thought it was a good idea to have a vent for each valve cover? I don't see any reason you couldn't put a regular cap back on.

We need more to go on as to where the leak is coming from. Clean it off with some simple green an run it for a few days and try to see if it's coming from the front or back. Mine leaks from the hpop lines at the head. Been meaning to fix it but it's fishing season

When I took it to the shop we cleaned out the valley at the top of the motor and fount that the leak was coming from the arm out of the pedestal even after replacing the whole assembly. Also if you guys know of any good tuners and diesel performance shops in San Diego It would be most helpful.

Then I'd do the pedestal mod or get a blank pedestal. You really don't need an ebpv in so cal.

Okay where do i go to find the info and parts needed to mod the pedestal so that i can seal that up? Also there is some blow by coming from the the oil cap vent and crank case vent which i know in these trucks is normal; i just wanted to add that to the equation as well.
