thank you for your great help. There are many ideas I can follow and work on. And now I know, that a tight engine is not the end of the world, but the beginning of a normal engine. All these things make me sleep much better.
I will work on the battery issue as soon as possible. For some other things I will have to take the car out of the garage, what will happen in spring.
As soon as I have new results or questions, I will post it here.
