I m new here in these forum. I have a Bavaria 32 Cruiser with Volvo D1-30 engine and 130s-b saildrive. Yesterday I saw oil at the upper unit of the saildrive like your case in 2013. Thé oil comes form dipstick or suction pipe. In your post you just described my problem with oil leakage. How did you solve the problem ? I think the oil comes from the execution/suction pipe by the dipstick. If you can answer my question I will be very happy.
Thank you very much
