Thread: Question about L32 crank case pressure

Ok people as most of you know I did the full L32 swap but retained my L67 throttle body. I know you can tap the top of the throttle body where that plug is and run a vacuum line to the back of the Gen 5 SC to help aid the vacuum pressure. I'm wondering what size thread tap and die sets people are using. The reason I ask is because I blew the dip stick right out of the tube and got oil all over my engine.

i know its a 1/4 npt.. that should be enough for you

you got it..
