Yep, I found similar info in my shop manual. There were a few diagrams but no measurements. Mine has a closed oil cap, and pulls in air from the air filter which goes into the front driver's side of the valve cover via an inlet tube, and pulls it out the PCV valve in the back.
So that means the vented oil cap I bought from a member here is superfluous (even though it looks cool). I still have the closed cap somewhere I think.
Regarding parts, I need to find both the proper grommet for the top where the PCV valve plugs in, as well as the front driver's side where this tube connects. I can at least find PCV grommets w/ an ID of 11/16" but I can't find any mention of the grommet for this inlet tube.
