Thread: need to find a vacuum source

Hey guys. Im wrapping up the turbo build on my 04 and I have the stock L26 intake on top of the motor. Where do I need to install a vacuum nipple? Im not getting vacuum from that one nipple on top but from what I've heard im not supposed to be.....

back of your intake next to the brake booster line is a nipple for a vac line. its for the hvac but you can tap it if need be.


see nipple?

I can't get to it. My waste gate is in the way

what line do you need vacuum for?

vac line is soft and very flexible, you should be able to get it on there and route it safely away from any pipes.

Need it for my boost controller, wastegate, and bov.

thats the only port im aware of. you'll need to get to it some how i guess.

Ill try an elbow. That's the evaporation port right?

that port is where the hvac line should go. or the air flow wont change direction in the car, aka vents, floor, defrost.

04+ is all electric hvac. they never had vacuum hvac controls

hes got a port he could run block off off, hes just saying its tight to get to. nothing a pair of long needle nose pliers cant fix in my book.

pull off the upper intake and drill tap the side of your upper pcv housing for a 1/8th npt to nipple fitting.

since your turbo im betting you have an RTV filled PCV valve witht he OEM Oring or the lim blocked off (in either case make sure you get rid of the plastic pcv distribution "J" tube that clips into the UIM gasket carrier...)

all you have to do is tap into that chamber or the backside of the EVAP/Purge solenoid boss and youll be good to go (drill bit/tap would point towards cyl 4, neatly clearing your WG)
