Joe , if the EBpv is not working what wood be the problem, and if this valve doesn't work it wood probably to excessive blue smoke on cold start ups correct.
Thanks for the welcome Joe,
If it not my waste gate then what opens up and allows what sounds like air pressure going through the exhaust and when you give the truck fuel you hear a chirp like valve or gate closing and when you let up off the fuel it opens and allows the air pressure sound...
Hey I am new here and I am needing some help my 2000 SD 7.3 during warm up cycle the engin is reving up to faster idle but the waste gate is not opening up to help it warm up. I have replaced the cold air senser in the air box what should I do next.
