We redid the valve cover when we replaced the VC gasket and in the process replace the pair of CCVs on the cover. There is a bit of a gap between the pieces (they swivel easy when not hooked up to hose and can lift up a small amount) and the cover and wanted to know if those should be air tight? Should I use a little high-temp rtv to seal the edges?

I've got a high pitched whine/squeal coming somewhere from the engine bay. It's not the belt and its only when I'm accelerating hard. Could be the fan clutch but last I checked it was tight. 98, I6, AW4

Check that the fan isn't hitting the fan shroud. Mine did this and drove me crazy. The torque of the engine under acceleration will move the fan, and if the shroud isn't in the notches below just right it'll hit.

That could be it. I just went out, put it in drive, stood on the brakes and revved to 1500 and as the motor reached its upmost motion from the motor mounts I heard the squeal. It's hard to pinpoint but with my head under the hood it sounded more like it was coming from underneath the VC
