DIY: Dual Catch Cans with Air/Oil Separators... On the CHEAP!

Ryguy

That makes sense, however, it doesn't answer my question. I could be wrong but at least on my car, which I don't see why it would be different than anyone else's, there appears to be more than one vent on each side of the engine.

The red tube is what is replaced with all the catch can systems that I have seen, however, on the same location over the middle cylinders on each side, there is, what looks like, a vent and is recirculated back into the intake. So really my question is, does this tubing also act as a recirculation? And if so, wouldn't this also need to be connected to the catch can system?

Don't worry about the other valve on the valve cover. that should be left alone. you only use the front PCV valve, don't touch the rear one.

Your red line, the Z1 one, it goes from your Valve cover to you intake manifold right? your catch can needs to be T'd into that line.
