Introducing the gas saving.....

I have a $2 fuel filter inline from the valve cover to the intake system. Only reason I have it is b/c for a while I had the valve cover tube going to the Atmoshpere and didn't wanter dirt getting in. so after a few days I hooked the tube back up to the intake pipe and left the filter inline. I see it's got some dirt and junk in it, some oil film. nothing crazy yet and it's been 1yr.

$160 is a little steep for something I can buy at Home Depot for $25. I guess you are paying for the anodized aluminum. It does look like it is built well though, so I guess you pay a premium for that. I prefer also to see what is going on in there, so the pneumatic oiler (with the glass container) would be my preference. However, I can see the advantage of having the intake and exhaust at right angles in the catch can. One would think you would catch more stuff that way.

I think the advantage of the catch can strategy is that it collects liquids. When the contaminants are vapor, I dont expect that there is much of a proplem. I use to use a home-made version which constisted of a metal paint can (appropriate holes in the lid) in-line with the PCV. It was connected directly to the air intake for the carburator. I had enough hose to allow the can to rest on the exhaust manifold. When the engine got hot, the fluids would evaporate and get sucked through the engine. I cleaned it every 3 months or so. I was primarily making sure that it didn't get full and then pass into the intake as liquid. In the summer, it would sometimes get a little coking on the bottom of the can.
