hey guys i got my bbk intake on and i dont know if this matters but the hose that comes from the passenger side valve cover that goes to the top of the throttle body has a hole on my stock ls1 intake but the bbk dont have a hole on the intake where the tb goes for that hose.
is this some thing i need to worry about or not?

shaun

soul tkr did you leave your egr tube blocked off at the manifold?

Are you talking about the PCV tube on the intake?

yea... i took the whole EGR and AIR systems out...

shaun

thatnks for the pic.
its the hose that i out lined in the pic.
its a vent tube but behind the tb there is no hole or any way for the tube to work on the intake.

Im sure its the same on the stock intakes. Theres just a small opening that doesnt go anywhere. The point of that tube is to provide a fresh air source for the crankcase. Basically filtered air from in front of the TB.

ill check on my ls1 intake to see if it goes into the intake.
if ya guys got any more idea's post em up.

your either talking about the port of the side of the intake that is PCV. Or your talking about the big hole that was in your ls1 intake, that hole of for the EGR, in which case youll have to take your EGR system off bc there is no hole for that on the BBK.

That tube is part of your pcv system and it goes to your passenger side valve cover, not the intake

look at the pic i posted in my last post i circled it.

I think he's talking about the nipple on the side of the stock intake that the PCV line plugs into.

shaun

No it goes from the front passenger side valve cover to the vacume port on the top of the tb

how about you take a pic of the ls1 next to the bbk one. that would clear up all the confusion.

what that is and does
its a fresh air vent tube, it pulls fresh air that going to the tb into your motor,
if you look at the tb you will see where(i the front of it)the air goes for that
DO NOT PUT THIS LINE INTO YOU INTAKE
put this back on the tb, if your tb does not have a provision for it(some dont but most do) then just put a small breather on it

so if im running a breather system, could i take the breather off the oil cap area and just put a breather at the end of this tube and block off the throttle body??? or is my system good as it is??

There are two ports - one is fresh air from the TB to the forward port on the passenger side valve cover, the other is vaccum - on the intake manifold behind the throttlebody and connects to the rear two ports on the valve covers, connected by the y hose. So the intake should have one and the throttle body should have one.

it work perfectly fine going to the tb and keeps you engine bay looking better
