If it does, at least you will be pretty sure that the problem is heat related and is inside the mixer box. BTW, where are the sonic valves for your hot air source located? I understand that some engines had the sonic valves located on the hot side of the intercooler which produced really hot, hot-air. If so, super hot air might be the culpret. Just a thought.
