So the blowby post didn't yield any results, but is still an issue with this new truck. In addition to the blowby issue it also has a cold start problem. I have checked and replaced the valve cover gaskets, uvc's, and the guy I got the truck from just had the gp's replaced. Changing the uvc's helped the rough idle issues some, but it still has a slight miss and a hesitation. He also had a new turbo put on it, not completely sure why. If the old turbo quit or scattered this could explain some of the other problems. One thing that I am having a problem with is that the WTS lamp only comes on for maybe 5 seconds regardless of the temps. It has been down into the low 40's this week in the mornings and I have been letting the gp's run until the volt meter has come back up and the gpr has kicked out. It has a new alternator, batts, IPR overhaul, still needs to have the CPS recall done on it. Any help getting me started on the right path would be great. I have all of my performance goodies ready to install, but want to take care of the basics first.
Thanks, Justin

 

Sounds like its time for a compression test. Blow by and miss when cold are common low compression issues. Old turbo was probably dusted.

 

The lamp for the WTS is independent of GP on times ( just a reminder)...

 

What about the CPS? I learned that even if it was replaced only 5 days ago, BY THE DEALER, it can still be a bad one.
My truck wouldn't start and then would run for 30 min then only 3.

Replace the CPS and be done with it.
