General Discussion / Re: Mysterious oil dripping on my loop
« Last post by pehayes on Today at 12:16:59 AM »Unlike the engine, there isn't any real 'pressure' inside the transmission box. There is a puddle of oil at the bottom and the lowest gears reside in that puddle. As the gears turn, the teeth 'lift' oil and transfer it to gears higher up. As they spin the gears do 'fling' some oil away but there isn't pressure. Hard to imagine pushing any oil up 18" of hose. Have you used the same brand of gear oil all these years? Some brands of oil are more prone to making foam than other brands. Perhaps experiment with a different brand? The internal circulation can lead to foaming like dish soap suds. If those bubbles have a very strong surface tension they might stay as bubbles and gradually rise through your hose. Any way to cut off half the hose and then replace the missing half with a larger internal diameter? The larger ID would promote breaking of the bubbles and allow the liquid oil residue to drain back to the box.
