So a question came up over beers this evening...
Seems a common source of small oil drips are the little rubber hoses joining the hard lines from the cylinders to the oil sump...the oil "scavenge" or return lines. Hard line from the cylinders to rubber hose to the engine.
Why don't they use flexible hoses all the way? IIRC, the engine connection is an NPT fitting with a nipple or barb...couldn't one put an AN fitting with flared tube on that end, and then run a flex line with flared ends at both ends between the cylinder and the engine?
I don't plan on doing this, of course, just wondering why it's such a jerry-rigged, cobbled-together-looking combination of fittings and aluminum tube and rubber hose and hose clamps, and not something more, well, elegant.
