It is entirely possible - My first rebuild was to replace broken compression rings.
The breakage was attributed to a lean condition at middle engine speed that likely caused detonation, leading to the broken rings.
I didn't split the case at that time.

New bearings it is.
Question is whether the available Glyco are acceptable or to spend the serious money on the Porsche parts?
