Anyone have oil catch can mounting pics?

Mighty Mouse makes an awesome catch can. Also has a nice drain hose that I routed to the underside of the car, easy to drain. Mine is has a -10an off the valve cover as the feed to the can. The filter on the top of the can has a one way release and only vents there if too much pressure builds in the can, it's a nice safety net.

I installed a Speed Engineering catch can, similar (identical) to the Mike Norris can. I got it from ebay for $76 shipped. http://www.ebay.com/itm/LS-Catch-Can...53.m2749.l2649
Good quality and made it to me with super-quick shipping ~ 2 days.
Has anyone else noticed that their catch can made the engine run smoother? I'm not sure if it's just the placebo effect, but it seems as though some highway vibrations around 2k rpm have been toned down significantly. Also when I have the exhaust cutouts open and I make a half throttle pull then clutch-in to shift casually there is not a loud pop that would typically be present before. The engine just seems to run better with less noticeable vibration through my poly engine mounts. I wish I'd done this sooner considering how easy and inexpensive it was.
I also added an inexpensive on the fresh air inlet to the valve cover port. There was some evidence of oil in that line, indicating that in some situations like a decel downshift for engine braking, the intake would actually suck some oil from the valve cover. The check valve is a one way valve and should not allow any oil or air to flow in that direction. It should only be drawing metered air from in front of the TB which flows into the crank case and drawn out through the valley cover PCV valve, through the catch can, and then into the intake manifold.
I feel like I've seen a lot of confusion relating to routing and whether a double catch can setup or breathers are necessary. For an NA car, I feel this is the easiest and least expensive setup that is very effective.
Mine is set up just like this diagram with the only difference being an inline check valve on the clean side. Hope this helps those seeking the same mod.
