Good evening everyone.

My Green Roadster has recently developed an oil drip problem. Within about 1,000 miles, the oil loss on the rear clutch side suddenly increased to more than 300 ml/0,6 pint on 100 miles, and the trend is increasing.

It's not dripping down the oil pan, but from the clutch bell housing bore = rear crankshaft bearing.

It's thick 60-weight oil, and I keep the oil level in the lower quarter of the dipstick.

If I've read and understood that correctly, it's due to a blockage in the oil return tube on the rear crankshaft bearing. However, that's unlikely, since I change the HD cleaning oil (API SC) every 1,000 miles and use an oil filter.

Does anyone have any other advice?
Thanks in advance!
