Evening James and all,
I replaced both engine head bolts with new ones (I suspected that maybe they were a bit bent) and had influenced the rocker brackets.
I fitted 2 new push rods.
I placed carefully the rocker brackets back on place and shimmed one of them on one side as there was to much play there.
I (very) carefully adjusted the valve clearance.
I checked that the motor oil level is correct.
I switched to 2 Escitalopram at the evening instead of only 1.

One of the above or (apparently) the whole complex had a positive effect on the situation.

I apologize for forgetting to update, my thoughts are elsewhere at the moment.
I hope this thread helps others in the future.
