I'm resealing the PCV baffle to the inside of the valve cover on a "Shelby" and "Turbo" valve cover. They both use the same baffle and seal with RTV. It looks pretty straightforward, but do you need to put RTV in the upper groove that the baffle seats into? Any other tips so I can get this right the first time? Never messed with them before until now. I've already stripped and bead blasted the valve cover and baffle separately.
