I've done a bit a research on the EBPV Delete for the OBS 7.3's and decided I'm going to delete mine. I bought this truck in the fall as a project truck and now I'm in the process of putting the motor all back together and when I tore it apart there was a ton of oil in the valley and all over the pedistal so deciding to delete the EBPV to prevent any future problems. For deleting it I plan on buying the pedistal that doesn't have the actuator and the new turbo I'm buying doesn't have the butterfly valve either. Now I have a few more questions I need help answering that I didn't see on any of the other threads/forums.

1. Does deleting the EBPV throw a CEL? I read on Cali emissions trucks it will throw a light and non cali trucks it will just store a code but not throw the light so I should be good as far as not throwing a light right?

2. To my understanding the EBPV would be regulated by exhaust back pressure (as that's half it's name) so I would assume the EBP sensor (located coming off the passenger side exhaust manifold and mounted on top left of the HPOP) plays a major part in controlling the actuator opening and closing. That being said can you delete that sensor and the pipe between it and the exhaust manifold as well as deleting the actuator and butterfly valve?? The pipe and sensor I'm talking about is usually located in the location below.




I'm assuming you can't delete the EBP sensor because it plays a role in some other parts of the programming of the motor (I've read it plays part in the fuel trims but there was a lot of controversy whether it did or not) but never saw anyone say anything about it in any other forums. Again I'm just trying to simplify the engine compartment and getting rid of something that would no longer be doing anything wouldn't hurt. Plus would save me a couple bucks on the rebuild by not having to buy a new EBP Sensor and tube and would be one less thing to leak or go wrong.

Any help/input is appreciated!!

 

The EBPS has NO bearing on EBPV operation. The EBPV closes when ambient temperature (IAT) is below something like 40F (varies by year) on startup, and opens when you floor the go-pedal and when EOT reaches 150F.

The EBPV is not regulated by exhaust back pressure, it's the other way around. The EBPV increases exhaust back pressure when it closes.

 

I cut/welded my pedestal and removed the butterfly. The linkage arm is welded on in this pic because I removed the butterfly first and use the arm to locate the rod for the reservoir so it wouldn't leak oil. Later removed the pedestal and cut off the reservoir.

 

That's a really good idea actually!! I like the cutting off of the actuator from the pedestal then welding the spot on the pedestal where the oil feed veins would be for the actuator! Unfortunately I don't know how to weld aluminum but I bet I can get someone to do it for me for cheaper then the cost of the new pedestal, worst comes to worst it doesn't work out I just buy the new pedestal....I just hope there isn't a core charge for it if I did have to do that. Was it hard cutting off the actuator and then welding the veins that feed the actuator up?

 

No not hard. Have to be careful after welding to make sure that the oil passages are clear of debris.

 

Oh I will I'm super ADD about that stuff, I wash all my parts very well before they go back on the truck multiple times inside and out. Thanks again for showing me that!
