One on the left is from a later model car, 88-89, they had some sort of fresh air valve that that extra hose went ot. it was on the lid of the mas air flow. you can use it on any year though, just cap off that hose.

The air mixture valve. Has anyone been able to turn the screw in there? I have two and both are seized up.

I have that same port in mine and I can't turn the screw either (but it looks like it's punched on the side to not allow adjustment, however I bought one of these:

and it came with some weird aluminum collar (bottom left of pic) and there is nowhere on the pipe to accommodate this piece, and there's nowhere on the car to install it either. I thought it was the same type of port, unless it's provided in case you want to cut/weld it on...not too sure.

The collar is so you can weld it on you intake tube for a bypass valve recirculation hose attachment. That also the right part to weld on the ovcp and attach a turbo xs bov. Edited May 19, 2012 by JohnnyWadd
