Nostalgic piece
I've mounted this piece on my cast aluminum rocker arm cover.very much like the original Offenhauser vents were mounted. It's a little smaller than the Offenhauser vent but very functional. A nice uncommon class act on a classic engine that does not have a PCV system

Splash shield
The inner splash shield rubbed my rocker arms, so I removed it. I was getting a very minor leak at the cork gasket, so I replaced it with a paper/plastic gasket. In the future, I'll scuff the breather and valve cover surface to aid the RTV in sealing. Other wise, a very nice piece.

I have a cad 472 and cast aluminum valve covers.. Would one of each of these, one on each side be sufficient.? I do not have an oil fill either so would you recommend an oil filler as well. I do need to drill or cut holes in the covers to accomodate these parts.

Will the baffle clear a stock small block Chevrolet valve train with stock valve covers? If not will thick valve cover gaskets help or is a spacer needed?
