Ok guys so crawled under the truck and let it run for about 10 min. Air pressure only got to 80 lbs. I believe my hunch was right (the air pack). Basically when I turn the truck off I sprayed the entire air pack and all lines, I did not see any physical evidence of an air leak BUT there has been a constant hissing coming from the blow by tube that goes down by the turbo, I noticed that I large air line runs into this vent tube and that is where the hiss is coming from. I traced this line back to the air pack.
Also I noticed once I apply the brakes that hiss stops and once I let off it comes back.
What do you guys think? Obvious air pack rebuild? If so where is a good place to get a rebuild kit?
Thanks for the input welldigger aboit the hissing sound that basically described the symptom to a tee.
