Engine ok, but various other problems part 2

Thanks for the first tips. I didn't think that'd be so much on the first day. I would like to narrow the problem further:
1 climate change is now over, but the problem is still there
2 I obviously got the oil loss under control with the change of the valve cover seal, anyway the car after the usual day tour of 236 km neither smoked nor smelled after burnt oil.
2 It's not the UFOs, because the problem is above all. ==References== 80 up (rather partial load). ==References====External links== The Commission has not been able to take any action in this field.
3 It always occurs when I am already about I drove 150 km at "fleet gear".

Yesterday, I was wondering if it could be the distributor's fingers. I had this problem with an old 7-man, who had to hit a huge ignition bridge due to a broken finger and showed similar symptoms, but who had already been with a cold engine.

The camshafts are on the upper edge, which control the valves absolutely ok, but at the side crack edges they look like milled or beveled from what seems strange to me, because every cam here seems to be differently "milled". However, I do not think that this effect should have any effect on valve perforation.

Well, I'm grateful for every hint.

Yours sincerely,
Andi
