Vacuum routing help needed Hey guys, I am in the middle of an engine swap, and I need help hooking up all the vacuum hoses from the LS1.
There are lines off the tranny, the motor, and back through the firewall, with a couple of what looks like check valves. If anyone has a diagram or any insight that would be helpful, as I am stuck here.

I would recommend getting a GM Service Manual from Helms. Expensive.. but well worth the investment IMO.

Still a bit confused on how to route the LS1 a/c vacuum lines though, and how it has a T off the back of the intake manifold.
Also, the valve cover hoses... my motor never came with any.
Do they just connect to each other to help ventilation with the throttle body crankcase vent?

I was scatching my head. Wondering if he bought a used car that had a vacuum modulated tranny in it already
