so. I can report: all is tight and dry.
I hope this is a long time reward, as I am a bit fed up now... I just cant crawl under the car every day as its has been the lasst 2 month (finding time next to family and work).
to round up the percentage of doing well, I also changed the valve cover seals.
thus I also checked the valve play and head studs. all is good.
