Hi Josh- Thanks for the info. This looks like a fairly straightforward mod which should clean up the oil. I see the line running from the valve cover to your new canister. There are two other lines attached to the canister. The one on the bottom I am presuming is a drain. Where does the other one go? Is it just open toward the bottom of the engine? Dave
