I know this is an old thread, but I am new to the powerstroke community and have been doing a lot of searching. I figure when questions I have come up most of them will be applied to older threads.
I am considering doing the EBPV gut and pedestal trim mod. I understand the pressurized oil port into the cavity and the drainback port. The EBP solenoid activates that flow based off of what the EBP sensor tells it. I might even think of a way to pull the EBP solenoid and plug that hole, also.
What concerns me most is the trough type port mentioned in the quote below. Since that end of the EPBV cavity is not sealed, I am wondering if it is a makeshift vent for the oil passages (kind of like a crankcase vent). I am worried that plugging this hole could create some pressure in the passages and make oil leak somewhere it shouldn't.
Any thoughts?
Plus, have you had any problems with this mod, since it has been over a year?

YES :thumb:
The turbo needs oil for sure, but it doesn't get it from the EBPV actuator cavity.
On the snap side of the cavity there are 2 ports, one is for incoming pressurized oil, and the one on the bottom of the cavity is for drain back when the EBPV is de-energized. Then there is the trough typy cavity at the rear of the ebpv cavity, I can only guess at what this one is for. The trough cavity exposes the drain back from the turbo. I don't know why it would be open to the plunger side of the EBPV, which is not sealed. This explains all the crusty oil build up on the shaft of the plunger, and then also all along that side of the turbo pedestal.
So some one please slap me if I got all this wrongunish2:
I'm pretty sure I'm ok to seal all these up and not affect the turbo oil flow. At any rate, it's to late to turn back now. I'm going to putty up these holes and if it turns out I'm wrong, I'll buy a new pedestal :dunno:
