Hey guys, Once again I've spent days reading threads only to find the ones that have my answer the solution was never posted. So I have another issue, I have a MAJOR boost leak. I can't even build 1 psi. I have a homemade boost tester I made from a dieseltechron video (God bless) when I hook it up and supply air the air immediately vents out into the driver's side valve cover, I'm assuming into the ccv doghouse. I can't build any pressure whatsoever. I've read post that say some leakage there is expected. I've read some that very slow leakage there is expected. I have major leakage there. I recently rebuilt the injectors and when I did I had taken the ccv doghouse off and cleaned it. Did I possibly put it back together wrong? I've read the diesels don't have a pcv, but is there another kind of valve that is supposed to stop the boost from going into the valve cover/ccv doghouse ?
