I have an 88 T2 and I'm hoping you could lead me in the right path to removing my bac and air control. This stuff is in the way when I remove my turbo and I don't really think it needs to be there. If I block these off the only difference for running would be that I'd have to adjust idle at the throttle stop screw right? Could I then just join the coolant hose from the bac and cap off vacuum lines? Would it still run after? Thanks for any help.

Basically...yeah. Just make sure you block them off good. Vacuum leaks are a pain in the neck!
