Today is one of those days when it's best not to get up at all!
First, the Bosch service charges €170 so that I can definitively know that my pump is broken, then I remove a screw from the cylinder head, which I finally manage to remove after 2 hours, while I was trying to refute the diagnosis!

And then this stupid thermal insulation falls into this gap!

The search for the thermal seal failed!

Is there any possibility that the thermal insulation ring could fall into the timing belt drive from there, or am I just unnecessarily worried?
Greetings
