Vacuum hose diagram

[04SS6.0]

Looking for a vacuum hose diagram for a 2004 Silverado 1500 6.0L

 

I can hear a vacuum leak on the drivers side of the engine, cannot pin point it but my truck has 370,000km so ill just replace all the vacuum lines 

Did a vacuum leak test, i sit from 15-16.8 psi jumps back and forth in that area as idle changes, never hits the factory 17-22psi.

I have a 2004 5.3 which should be the same setup. The driver side valve cover line goes to the top of intake manifold and the brake booster goes to the back of the intake manifold. That is it. Best way to find a leak is with a smoke test.

Did a smoke test, 

i have leaks at the oil fill neck

2 injector o rings

 

vacuum hose from intake to passenger side valve cover, 

cannot find the right name for that hose to be able to look it up and order it. It not just called vacuum hose so searching for it it is annoying. 

Any idea on what its called?

probably something with "PCV" in it, like PCV hose.
