Boost leaks.

powerstroker888 · Dec 10, 2014

What's the best way to find boost leaks. I apparently have really bad leaks. I have 160/80 injectors and the most boost I can put out is 25. It also smokes like a freight train!! Any advice would be awesome!! Thanks!!

Truck in signature? Do you have an intercooler? It doesn't look like you do. You need to inspect the orange intake plenum boots, the intake y pipe o ring above them, that attaches to the compressor housing outlet on the turbo, and the intake plenum themselves can leak.

Ya trucks in sig. Sorry!! I do have an intercooler. And alright. If they are leaking there would be black soot right??

there would be soot around uppipe joints and at the manifolds. I created a capped ABS pipe assy with an air fitting that was installed in the air intake, then pressurized with 20psi of air pressure, listening for airleaks. The CAC, tube joints, plenums are all prone to leakage.
