Exhaust Back Pressure Valve

My 01 F550 seems like it needs a new one. I have no power at all when cold, once its warm the power is fine. I have yet to find a place, other than Ford, that sells them. Where can I get one? Or can I just clean it and reuse it?

if you see a light at the end of the tunnel, it's probably just a photon torpedo

I am not 100 percent sure but I think it wont have much power because when it is cold that valve is closed and restricted the turbo, mine is the same way I just let it warm up in the mornings and I am good to go about 15 minutes later.......Someone will chime into help u shortly though

How cold is it Justin. The EBPV only helps it warm up faster by keeping some of the exhaust heat in by blocking flow. I have mine disconnected and it only takes about 2 minutes longer to warm up at 30 degrees

That is correct. If its closed its gonna lack power. Does it make a hissing noise when it is lacking power

The valve should only be closed while the engine is cold. It may be sticking or may be operating correctly and is just a PITA. Let the truck warm before you drive it and you should not notice it. you can also disconnect it or just gut it if the temps don't get too cold in your area.

The issue I have is that the truck is a wrecker for our towing company. We get alot of calls that require us too hurry and we dont have 20 min to let it warm up. The truck has over 200,000 miles now. I was just curious if we could just replace it too see if it would help. I am by no means a diesel person so if someone else has a better idea on what too look for than please chime in. When the truck is cold it will not hardly move at all, no power. Put it too the floor and it doesnt even want too move at all.

That's normal for a cold powerstroke. If you replace the EBPV, it will probably be the same. diesels love heat and powerstrokes like it even better than other ones. If you have to be ready to go in a flash, you should take Dave's advice and plug it up.

The temperature here has been ranging from 60 to 100. I can plug the truck in and I plan on it for the winter. I just know something is wrong when its 90 degrees outside and it takes the truck 15 min to get enough power to pretty much move itself.
