SR/ PCV hookups?

I've got the full Accel SR package, base to Throttle Body. I've tried a few ways of hooking up the PCV valves, none great.
There's a new 383 going in this week.
Suggestions?
Thanks.

Sure! First, there is only one PCV - it goes in the driver's side VC. The other end of the hose gets plugged into an lower intake manifold fitting back by the #5 cylinder (the hose runs between the runners for 1 & 3 and the ones for 5 & 7). The passenger's side VC is supposed to have a vent - either a baffled or filtered breather, or a hose coming out of a elbow (not a PCV valve) and plugging into the larger of the two ports on the passenger's side of the throttle body. This side is providing the source of fresh filtered air for the PCV to be able to draw the fumes out of the crank case.

Got it...

Thanks Vern.
I remember hooking it up that way when I first got it. It was a mess. However, I now realize that was because the 355 I had then was beyond tired and getting a lot of blowby. The loose pistons were pumping lots of oil fumes out the PCV.

What goes on the throttle body port below the air source. I recall a note to cap it. Do you agree?

The other port on that side of the TB is for the charcoal canister. The fumes from the charcoal canister enter the TB at that point. If the CC has been removed, cap it off. The small port on the bottom of the TB goes to the EGR solenoid. How's that?

fuel tank vent

Vern-
That's a pretty cool rundown.
The charcoal cannister went through ignorance and need for the space (battery is there now). The cannister had the fuel tank vent hooked to it. I've got that vent with a small K&N and one of those small vacuum operated air valves. That way the tank vent is opened only when the engine is running. I think I even had the small K&N near the big one for the engine. Some warped try at civic responsibility, I guess.
What are your thoughts on getting rid of the small K&N and hooking the vent to the port for the cannister? Would it be too volatile without the cannister interceding?

I'd probably put a canister back on it and just relocate it to where ever you have room.
