…I looked inside with a mirror and noticed that the very end of the flaps arm is loose. There’s a plastic ring that goes around and holds the arm. This ring is embedded into the manifold itself. This ring was floating around inside one of the valves.
In order to fix this, the manifold would have to be split open, at that point I would just completely delete the flaps. How do I open the manifold? I took out all the bolts but it seems that the two halve are glued with super bondo weld stuff.
