Hallo und guten Abend.
I've only made a little progress. The two nuts on the rear bearing cap are so tight that I can't loosen them.
I'll have to try it again with an impact wrench tomorrow. In the oil pan, I only found a little steel shaving, 3 x 2 mm and 0.05 mm thick.
However, the aluminum camshaft gear was rubbing against the cork gasket that protrudes on the inside. Since the oil pan and filter screen were clean, the sludge is in the oil filter.
A note for those who insist on using unalloyed motor oil: The picture shows how clean the oil pan and the intermediate plate are. They were only degreased with brake cleaner. I use exclusively 20W-50 HD Oil classified API S

Bis morgen, beste Oelfinger Gruesse!
