vacuum pipe under Throttle body

[andyg plym]

evening all, just a quick question; the pipe that goes from the pcv system to the underside of the inlet manifold....ages ago I replaced it as it was damaged....but at that time I had no large hose so just used 8mm boost hose instead. its the pipe that is directly under the throttle body that you very rarely see on here.
Could this potentially reduce boost output?

You want all that stuff to be air tight.

oh its air tight alright, just hope the diametre wasnt too small?

If you keep the interior diameter of the intake manifold's elbow(at least ) you'll be fine .

All it does is suck vapour from the breather system when you shut the throttle, 8mm hose is fine.

Is your one way valve ok? If you've got it apart it would be worth checking it.

[andyg plym]

I replaced it a few months back as it was leaking

Ditch all that and connect the N80 directly to the inlet and fit a catch tank
