Klaus:

Just commpleted the O ring installation on son's 94 850. Great learining experience for sure. One thing I noticed with the pan off is a square port which connects to the engine venting system or oil trap. This even seemed somewhat blocked toward the bottom of the pan. After vatting it and receivng it back there still was a lot of varnish in the bottom. Took some Turtle Wax Oil Eater and that cleaned all the varnish off. It appears that if there is too much sludge build up in the pan that this return port might block. This is a need 200K engine that has not always had perfect care. Anyway, an observation. This is quite an engine that Porsche designed for Volvo!

Next: timing belt and soon RMS.
