ok I'll try it and at least that will tell me if it moves. My concern is that maybe I through it off and now for example it could always be somewhat open and the computer wouldn't be able to tell etc. Not sure how the computer would read the home 'closed' position or maybe the spring will always return i to the home position and there is no worry. I also bought some Berryman's B-12 (last time I used seafoam only cuz I couldn't find the Berrymans). I don't suppose there is any harm in cleaning i twice in a row and then changing the oil. Oughta be pretty clean then. Also put a can of Berryman's in the tank too.
