The torn thread of the cylinder head for the valve cover could be easily repaired with it. Since the repair was fast and easy, I have the same precaution all threads that were accessible in the installed state with renewed precaution. Altogether there were 8 pieces.
Repair time for a 4-cylinder M43 engine = 1.5 hours by electric screwdriver. At first glance, one sees no difference to the original thread.
The valve cap is firmly back on it and seals again.
So I have at least 100 savings on servicing costs and still have the ability to repair 52 other threads.
With minimal technical skills that everyone should hammer out with the repair kit.
Perfect!
(Side note: As I performed the repair that's just what advanced;.))
