Does anyone have a diagram of the series 1 (aluminum plenum) PCV system? Trying to figure out which ports are where that I need to tap and plug when I change over to a catch can and breather setup.

I would have to dig out my FSM, but even so, it would be for a 93-94 L27, which uses the plastic upper with EGR setup.

You would be looking for the 91-92 L27 config, which I believe J Wikoff may have info on.

As I understand it however, it seems like it would be pretty straight forward, especially if you were looking at it. PCV is on the belt side of the UIM, and pulls from the LIM.

Is this going on top of the twin charged setup?

Yeah, this is for my truck. I know where the PCV valve is, but need to know where the other side of the system is (ie, is there something in the TB like the series 2?)
