Appears to work well for my street driving.

The ADD W1 is compact and very well made. Bottom half spins off
to empty but also has the convenience of a dipstick to check residue levels.

I looked up these parts to get a better feel for them, and that did it, that's the route I'm going with on the 408 for starters. Seriously, for all those who may wonder, they're worth a peek. ADD W1 has a good...no great- looking product, but limited info on part origin or company location. ME Wagner is out of Bear Creek, Pa. where they make their stuff in house. Thanks for the tip.

Based on Tommy's explanation of the way it works, along with everyone else's information, I now understand that a properly functioning PCV will likely solve an oil-smoke filled cab issue with Windsor #3 of the "3 Windsors" thread elsewhere on this forum. (Please bear with me for a bit, I will get some photos and update the other thread shortly)
