web site that the Aux Air Valve was no longer available but easy to repair. He is correct. It took me about an hour to do the job. I used a screw driver and a hammer to pry open the pinch seam. Once I got it open I saw that the rotary valve was frozen from rust, dirt and carbon build up. The bottom contains a wire heater element and a ceramic piece . I cleaned it out gently, being careful not to break the heater wire and put it off to the side . The top assembly has the hose connestions and the bi-metal spring that turns the valve when it gets hot. One screw holds the bi-metal spring, I removed this. I sprayed the valve shaft, body and inner cavities with a combo of carb spray and WD-40. Let it sit a while, plugged the holes, shook it up. once I got the inside nice and clean, I put a few drops of 30wt oil in there and worked the shaft until it turned freely. I used some JB weld on the top right angle hose connection to seal it since the pinch seam was leaking air. When I re assembled the top to the bottom, I also used some hi temp silicone to seal the heater chamber. Now it work and the car idles correctly after warm up
thanks Brad!
