"I have a MD11C with MSB gearb
"I have a MD11C with MSB gearbox and heat exchanger. When I bought the boat 5 years ago, the previous owner old me that I would need to add 1 1/2 fluid ounces of oil to the transmission every 6-10 hours. He was correct. I have tried finding where the oil is going - unsuccessfully. Even some good local Volvo mechanics can't find it. It has been suggested it might be a blocked breather - but I can't find a breather on the MSB. I wonder of it could be flowing through directly to the maon crankcase sump. There seems to be an extremely fine "aerosol" type spray of clean oil over the top of the oil filter and each time I change the filter it gets covered again - so some oil is definitely leaking... I just can't find where. Any suggestions or ideas?"
