  1. I've tried the PAI number as well. All I see is "part not available "
  2. Since I posted earlier about turbo boost failing, I did some trading between 2 trucks..... I swapped the VGT turbo valve between trucks, and now the original truck is working fine and the donor truck is failing. So I'm looking for a VGT turbo valve to replace the faulty one. The Mack part number is 25101072 . I've checked everywhere I can think of to find one and nobody seems to have one. Backorder is all I hear. Anyone here have any suggestions as to where I could find one? It would be greatly appreciated.
  3. It's not storing any codes and yes I replaced the turbo filter....
  4. Fuel appears to be ok. The lightning bole comes on and that kills boost. Lightning bolt has come on or off over the years with no issues but not this time.
  5. I'm at a loss! I have a 2007 CXN613 that loses boost for some reason. I've replaced turbo, air-to-air, piping to turbo, rebuilt VTG valve. When I start out, I have nearly 40 pounds of boost, then, 10 minutes or 4 hours, no rhyme or reason, it just loses pressure until I pull over and shut it down. After I restart, its good for a short time until it drops again .... Any ideas?
