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 |

They appeared in 1973, possibly even in 1972. If your engine has a PCV valve in the oul filler box, you need them. If you have "enhanced" the induction system, say with big carbs, you need them. If in doubt, keep them. The factory thought they were important enough to add them, maybe your engineering department should consider it, too. The Cap'n |
