Would it matter which side of the temp vac switch was hooked up?
I seem to recall they are switched so the egr is on the left (pass) side port not right.
this diagram is correct except green valve is on outer side of engine
I hate playning with them as those plastic ports get brittle & crack.
I'm guessing they lead to a center port that opens at 50 C so it owuldn't matter which side they were connected????
If it closes at 50 then it would block air from intake manifold...don't know if tthat would be good??
Help...which is it open ir close at 50C...or does it close half of the loop?
Anyway does it matter which port of the TVV it is hooked on???

Looks like it, if that is the case there has to be some sort of restriction or purge valve to control the system.

There is a electrical connection not connected on driver side intake center & a missing connection sort of like a 2 pin female plug also on the drivers side near wall. I have no idea what these were once plugged into.
Also try to hide them from smog eyes...LOL

If the hose is plugged at the throttle body, there will be no adverse affect on tail pipe emssions.

This would be the fresh air inlet to the can.

Is this good? it couldn't feed fuel fumes into air cleaner?
Is leaving it open ok better? its been running with a open black can.
I'm just concerned it could effect vacuum.
Just remebered there is a 5mm metal port coming out of the intake on the back passenger side. It hooks up to a line that runs along back & goes into one of those 4 or 5 otopus connects that go behind firewall toward fuse box...More unchatered territory
Every bit helps
Thanks so much!!!!
