Is there enough room inside the intake manifold for the pin to wriggle free and get into the engine? The pin on my car's DISA unit came out completely while I was removing it from the manifold last year, and I spent several tense minutes locating it in the engine bay. After retrieving the pin, I cleaned it off, pushed it back into the flap, and reinstalled the DISA unit.

Since the DISA unit slides into a channel between the two halves of the intake manifold, I have my doubts that the pin would even be able to get loose in there and do a tap-dance inside one of the cylinders - but I'd like to hear from someone who has studied the system more thoroughly.
