Yet another mystery vacuum leak - solved!

For those of you with a venerable classic 900 with an AC system. Specifically the 8V. You know that idle enhancement valve that opens when the AC compressor kicks on? I discovered that mine had a considerable leak! I had removed it to reposition the wiring below, then just for the heck of it I did the blow test after closing off one end with my thumb. Sure enough, a vac leak. It wasn't difficult to see exactly where the leak was because of a telltale oil and dirt trail along the seam where the metal meets the plastic. With no working replacement, I opted to fix it with good old JB Weld. So that makes two mystery leaks fixed with JB Weld. The other leak was discovered on the bottom lip of the aux air valve. That leak I've known about for some time and was fixed at that time. I have no idea how long this new one had been in play.
