Looking at Brad's photo here, he's put a filter on top of the nipple at rear of the valve cover.

In photos I took before disassembly/beginning this project, I had hose going from this nipple to stock air cleaner housing.

My Weber kit came with a plastic nipple matching hose size for that valve cover nipple, and I had assumed I would get hose to connect from that valve cover nipple to my Weber filter housing (hole for included plastic nipple is on bottom of Air Clearner housing, adjacent to block). Is this appropriate/recomended?... or is their good reason to do as Brad's done (filter) w/the Weber setup?

I've read elsewhere here, if I understood correctly, this routing could result in water vapor making it's way back into engine oil.

Appreciate any clarification on this.

Thx.
