Datsun C.A.C valve

[dpdatsunman]

I have a 78 datsun king cab. i'm try to smog it and the CAC valve decided to die on me. there are no auto parts stores that sell it still that i know of, so i was hoping that maybe one of you guys had one that you would be willing to sell. or know of a place i could get a new replacement. any help would be greatly appreciated.

Have you tried your friendly local neighborhood Nissan dealer?

[dpdatsunman]

they actually don't have a nissan dealer in my town. I called every auto parts store in town and no one could get it. The local smog shop is working on it now. If they can't get it, I will go to a referee and try to get smog exemption.

I called Nissan, and they discontinued the part. They gave me the number for a guy in the bay area, and he said he would look in his warehouse this weekend.

I am not sure what part you need ..could you take a picture of unit i may have one ..........My son is fixing a 79 510 wagon and where we are located in Washington we are emissions exempt. So we took off a bunch of that stuff recently..Not sure if it worked but cars in pretty good shape for it`s age.

C.A.C. Valve is part of the Air Pump system.

 

later models:

 

* C.A.C. valve. One hose tees into the pump output, the other hose dumps to the air (apparently not connected to anything). This valve has a single vacuum hose to control it

Also used without Air Pump, on models with Air Induction by reed valve.

 

a C.A.C. valve which controls flow to prevent overheating of catalytic convertor.
