You don't want to do that, you will flow air to that cylinder through the PCV and make it run lean.

So it will effect that much .Hmmm I cant see where I could vent the pcv that would give me equal distribution in the manifold

If you can't get a spacer in there, why not drill/tap a hole in one side of the plenum for a fitting. Then the PCV will be shared by four cylinders.

Like stated above. Do not use that port for the PCV. I tried that and it constantly oil fouled spark plug#8. I have a small spacer under my carb with a fitting in the rear. You can sort of see the setup here..Engine pic

Bill, there was a plug in mine the same color as the base plate. The hole is the correct size to tap a 1/4' (I think) pipe thread

Geeez, my memory is going or maybe gone . I am sure there was already a hole there but quite possible I drilled and tapped it. I actually talked to Patrick about the vacuum port and he told me what to do.

A little more work, but you could vent it to the headers.Just a thought.
I have been running a race type pan evac on the street to one header ......it does work but under prolonged idle or slow speed high vacuum it works too good the header scavenge the vapour and and pulls oil out with vapour making for a smokey idle ....... have not been able to bafle it to solve problem ..so want to try pcv for street use ..........going to plumb to one side of dual plane and see what happens
