Anyone have any tips to lock the valve open? The diaphragm is cracked and leaks air. I've been trying to get the car smogged and already failed 3 times. I wonder why mazda didn't have the valve fail open instead since port air is essential for emissions.

 

you can shim it, old old trick. i think Mazda has it default to dumping, to keep the heat down

 

Any instructions toward how to shim it?

 

bump, anyone else have any tips?

 

you unscrew the valve, and put a nut in there, put it back together, and make sure the air goes in the direction you want, done
