Is the any prefered vacum lines i should be teeing into?
Because I either have a poor vacum line or i need a new blow off valve.
I am currenty using a vacum line close to my brake booster on the backside of the engine.
Any pictures of vacum lines people are using?

 

teeing into for what?

 

from my engine to my boost gauge and blow off valve

 

Of those three/four nipples on the back of the throttle body, only one is vacuum. The others.........are not vacuum. Just FYI. The preferred place for a line to the bov is from the original stock location, which is about a quater inch aft of the BAC's air feed line and almost on the flange of the upper intake manifold. The nipple is just aft of the bac's air feed line is another way of putting it.

Or, there is a approx 1/2 inch nipple just aft of the bac, and just barely above the bac, that was used to feed air from the air bypass solenoid to the intake. If the air bypass solenoid has been removed. then that nipple is not being used for anything right now and it'd work for your bov.

I'm talking series four turbo.

Or if you have a bockoff plate for the acv, there are three possible places on that blockoff plate where a nipple can be drilled/installed for access to the intake runners.
