Just what I need, gives me a lot of ideas of how to do mine. My PCV hole is baffled and the baffle box surrounding it is held in place with 4 screws. Here's a picture of it from when I first bought the cover. It now has two boxes there (one for the oil fill cap) and is blasted clean. The one on the left is the PCV.

It is dead in the center of the cover. I think I can braze a sheet of metal to it that will go side to side and top to bottom and achieve the same effect. It may have small gaps around the edges and some at the bottom but not much if I trim to fit. Or possibly weld in an aluminum wall in the same area.
Much appreciated.
