EBPV Disconnect
I am tired of trying to drive a slug in the cold weather due to the back pressure valve, not to mention it sounds terrible with the converter removed. I was wondering how to disconnect it. Thanks

Right in front of the turbo there should be a little 2 wire connector, between the turbo and the fuel filter bowl, down by the base. I dont remember the wire colors but it is pretty much the only one right in front of the turbo, disconnect it, this will eliminate your EBPV from actuating. I did it and am so much happier, the sound and lack of power were horrible.

My friend Jeff in San Diego found a company that sells a module that turns the EBPV into an exhaust brake. Had a switch to enable/disable mounted on the dash, and a pedal switch to activate the brake with the dash switch on enable. Really cool setup, I'll get in touch with him and ask where he got his at.

The "module" will run you from about $80-$300 depending on what you get. The parts to do it yourself will run about $10. There is a company on ebay that sells one called the powerbraker or something like that. For ease of installation a ready made kit is the way to go. To save a buck or two you can buy the parts and build it yourself.

Thanks guys, I just can't stand that darn thing and it gets a lot of heads turning when I go through town because of the horrible sound comming from the straight through exhuast. I don't really have a need for the exhuast brake because there are hardly and hills in central Iowa but I will keep it in mind. By the way, I do have an automatic tranny and was wondering what the torque converter lock up was. Thanks for the info and thanks for the link KWIK!

Thanks Robbgt. I also have a 97 in case this makes a difference. I don't think it does though. Heck, does the thing even engage when the truck is at an idle? I don't hear a noise and it never warms up just sittin there. Just wondering

It doesn't hurt a thing to disconnect it as long as you don't live in a really cold climate. Places like Alaska, Colorado, Maine, you really need to keep that thing operational so the engine will be able to warm up at all. The zero degree weather and colder will introduce such cold air into the engine that it will take more heat out the exhaust than the engine can produce. Thus the need for the valve. I live in Seattle where it rarely freezes so I can safely run without it. I do occationally get into a freezing situation when I go to the mountains or eastern WA, but there I just make sure that I don't let it idle for more than a minute, I drive off and then the engine is working hard enough to warm up. I also made my wiring reversable so that I could put it back to factory config in case I ever go to a really cold place with the truck.

how cold is too cold? i like in mass... and sometimes it can get down maby into the 20's.... i am getting a stright throught exhuast... and i don't want to have it sound weard if the EBPV is activated... but i value engine life more than exhuast sound.... i usually start my truck in the mourning and let it idle for about 5-10 min before i leave..

A side note: If you really want to baby the motor consider a switch to Mobil 1 Delvac 5-40. The motor will run just as well cold on the synthetic as it does on the dino-oil warmed up. The dramatic reduction in cold engine diesel clatter is what sold me on it.
