Hello everyone!
Hope you are all well!
Many things got in the way of all this - but its all done.
Checked valves - all good except for 6 which was o.k. but still i adjusted it
Installed clear hoses - no bubbles
New filter
New blow-by hose
The car runs very well, most problems are gone - although the top speed is still unchanged max 115km/h maybe less (GPS info)
What now
*in the meantime the car drove ~1500km, it didnt really clean up, still smokes quite a lot.
