While pulling my carbs off I noticed that each head has an air vent. One was capped off, the other was open.

Where should these go and why are they needed? Will capping these contribute to oil leaks?

Here is a pic I found: http://www.914world.com/bbs2/uploads/blog-1...-1131214564.jpg

Thanks

With the vent next to oil filler and no PCV valve, on a car that did not have head vents stock... is there any potential benefit to adding head vents or is that redundant?

I sure would like to hear an answer to this.
Anybody willing to comment??
I'm at a point where installing this is still simple.
