Strange why has that happened , has a swirl flap fell in there , is that the head of the valve in the second round port along the head .
Not quite grasping them ports , looks like you can see valve in the round port but in the first round port it looks like casting , you normally have one shape port for direct air and another shape port for the swirl effect .
Rare to see a snapped valve , has something been sucked in from when it had a service ......something strange going here ??
