Was reading an article on here about removing the turbo and it said to request a how to sheet on gutting the EBPV. What is this and what does it do. Im going to install a banks compresser wheel and do a rebuild kit and would like to know the details of the EBPV to see if I need to do it or not. I hope I will be happy with the new compresser wheel. Will the new wheel make a diffrence like everyone talks about?

 

The EBPV is a butterfly valve placed where the downpipe bolts to the turbine housing on the turbo. In cold weather and when the engine is cold, the valve closes to put a load on the engine to aid in cold weather warming. It is supposed to work as the truck sits at idle.

There are several reasons for gutting it. One is for people who don't let their truck idle for long periods of time, so the EBPV is never really activated often. Another is people in warm climates who simply don't need it. If you plan to make huge power out of your engine, you'll probably see that valve as a restriction in your exhaust and take it out. The last reason is for those who experience frustration over it's faulty nature. At times they may close while driving, causing huge power loss and extremely high exhaust temps. The reason for closing is usually due to the exhaust backpressure sensor getting a false signal, like from a clogged sensor line, or just a malfunctioning sensor itself. Sometimes the valve itself can be so caked with soot that it sticks when it closes.

 

So does anybody have a write up sheet on doing a rebuild on the whole turbo and one for the EBPV gutting?

 

this is a good question. i've been doing some research on a how to clean the EBPV. since i'm still new to the PSD world, i was wondering if anyone had a how to or tech document with pictures on how to clean it.

has a excellent discription of how to clean the EBPV but no pics. i'm tempted to make a how to with pics and post them if someone can show me what the darn sensor looks like.

thanks.

 

I'm new too with no pic's but look in the "Powerstroke Bible":

Under Section 3:TURBOCHARGER, select TP-38 TURBOCHARGER WITH EXHAUST BACK PRESSURE VALVE. There's a nice closeup drawing of the EBPV.

I look forward to reading your EBPV Cleaning picture book. A good story always helps me go to sleep.
