I've managed to polish oil seal witness marks out of crank palms by hand before and ended up with a reliable seal. I've usually just uses abrasive Scotch Brite pads (dark red grade). It's hard going, the crank metal is hard. I use small pieces and work with thumbs. Be ready for sore thumbs! If you work around just until the mark disappears you can be fairly sure you're taking off about the same amount all round. Not had one leak after doing this (so far). Again ... K Series experience, may not be applicable!

The rear crank bearing cap is sealed in place to prevent leakage into the bellhousing. It could be that this seal has failed. It's an awkward job to do, sealing vertical and horizontal faces at the same time so perhaps I didn't do the job well enough. In any event, the engine is going to have to come out again.I have the time and the tools, the enthusiasm seems to be faltering though It'll be fine once I get going....
