Lower intake elbow has a hole right? Those are 20 bucks from dealer.
Are you going to rebuild your DISA with the G.A.S. kit or just get a new one? Usually the vaccuum pot is fine, you can test it via the instructions on the GAS website, the flapper, titanium pin/screw, bell crank lever, and O-ring are all superior to the OE design, I'm very happy with the kit I installed in my DISA, to know its basically made bulletproof while I own the vehicle.

EDIT: Just watched your video, the flapper has no spring to it at all? It is probably shot then, if you do have to get a new DISA I would preventatively put the rebuild kit on there, just to have the "death pin" out of the equation. You're lucky that pin didn't get sucked into the manifold and score the cylinder.
