The charcoal cannister captures gasoline and other organic vapor and prevents it from going into the atmosphere. The charcoal temporarily absorbs the vapors. Then it puts it back through the carb so it can be burned. It's a piece of emissions equipment.

I doubt it. However, this would render the off idle purge useless because the pressures are equalized between the two tubes. However, if you don't have any barrier (link an internal baffle) to oil getting into the PCV tube, you could get oil being sucked into the manifold that way. Is that tube really oily? Are you blowing smoke?

z-man, not blowing smoke of any kind, I thought the same thing about the baffle, it does have a baffle on the valve cover. I have heard from others that are using roller rockers, that they need to install oil restrictors in the block to reduce the oil to the top end?? Any thoughts out there
