pcv into carby

[DANNY8]

My 750 Holley only has one large vacuum port on it, which I'd wanna use for the brake booster. That creates the problem of now having no where for the pcv to go. Can I just put a t-piece in the vacuum line going to the brake booster or would that effect the brakes?

brake booster should be run off manifold vac, not off the carby. im not sure how the PCV would affect the consistancy of the vacuum going to your booster. cos that little valve opens and closes quite a lot.

personally i would just hook the booster up to manifold vac, where it is supposed to be. what manifold you using?

[DANNY8]

It's a procomp manifold. It has a bit along the back driver side runner which looks like it could be drilled out and tapped.....but obviously a bit hard now it's on the motor and don't really wanna pull it off.

Might just have to use a t-piece in the brake hose and just see how it goes. I guess another option is to use a small spacer under the carby and put a fitting in that.

Ya can just see it in this pic.

hmmm, i really dont know what affect the pcv will have on the booster. think it may drop the vac too much, but as ive never done it i cant say for sure... i suppose its worth a go hey?

you could always ditch the PCV and go with a regular breather? im assuming this thing isnt epa friendly anyway?

[DANNY8]

Yeah regular breathers sound like the go!

you might be able to port the PCV valve intot he air cleaner assembly that will sort out vacume might make the carbie messy if you get blow by at some stage
