Gutting the EBPV ped acuator Concerns? - Diesel Forum

Supercab79 · 03-25-2007, 10:44 PM

I would really like to do away with the whole acuator cylinder like I've seen some do but what is the ped made of? If you just gut the rod assembly and plug it does this starve the turbo for oil?

Any help would be great
Thanks Marc

The pedestal is aluminum. If you simply remove the actuator guts, you won't have a problem with oil-starving the turbo. Cheers!

I don't see how just gutting it up cannot cause a problem. There is a pressure hole in the cylinder that will leak right to the return if not welded.

Trust me it works fine did mine right before christmas no problems.

I'll second that. gutted the ebpv and actuator, tapped and plugged the actuator rod hole. no problems.

I would go with a modded turbo pedestal from Rick96F250 He will take care of you. He can send you a modded pedestal that will NEVER leak.

Why spend cash when you can spend alittle time modding what you have when doing other chores,I did mine when I was putting in transmission and new up pipe gaskets.It really is not that hard and its almost free pipe plug cost me change I had in my pocket. Just my .02

If it worked for you great, the modded pedestal WILL also make removing the turbo almost fun. Without the barrel for the actuator the back bolts almost jump out! To each his own. I'm not trying to bring down what you've done. I'm only offering an alternative.

It leaks right to the return on a normally functioning one that isn't gutted.

The plunger is in there to seal the two off.

444-4D · 03-26-2007, 10:41 PM

The plunger is in there to open and close the EBP valve.

Sounds like you've been on some website reading info that was written by someone who doesn't know how one works.

The plunger is in between the pressurized port and the big oil return passage. The other port also goes to the return but is controlled by the solenoid. If you take the plunger out you are letting presurized oil albeit a small amount (the pressurized port has about an .080 hole it)go directly to the return all the time instead of just when the pcm is calling for the ebpv to operate.

I agree with the ease of the bolt thing but, I will upgrade to a s/d ped. and such when I get a gerrett ball bearing. [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Not so good now. The PCM closes the EBP valve by blocking the return not by asking for oil supply. The oil supply is always there and is always dumping except when the EBP valve is closed. Any time the engine is warm the oil supply for the actuator is dumping into the return. BTW the supply hole is .040".

Understood. I don't plan on going that route. My next turbo will be the D66. My pedestal will remain and I still would recommend it to anyone. Rick did a great job fabbing and welding mine. All in all it is a GREAT mod and the price ain't all that bad either. The SD pedestal is a great idea too, but like I said I want to keep mine and most people on here will keep their stock turbo and now with the D66 out, I would imagine there really is that many less people that would change pedestals. The welded pedestal is very clean and neat plus makes the turbo removal easy and I will never again have any leak worries.
