continue to ponder this - seems to me a far cooler running engine could be had if the huff in of air was fresh(filtered) air and puff out of hot air went away but a better oil mist recovery would be needed I think
OOOOkay, I read my post & theres a HUGE hole in it.
Okay, a Y, one leg up, to let the engine exhale, the oil condenses & drains back in a parallel oil line, to bypass the exhaust reed valve, but it needs its own valve, to close when the exhaust reed opens, so as to not blow the condensed oil back away from the engine.
The return air is sucked in as the piston goes back up, thru the other leg of the Y. Its valve & the return oil valve work at the same time, so, it would be okay for the condensed oil line to go to the intake leg of the Y.
How about an "exhaust" pointed up with an "intake"( the whole thing is a Y) & some reed valves on it? The Exhaust,( with an air filter on top) pointed up, would give the oil a place to condense & drain back to the crankcase, thru a small tube set into it just above the reed valve.
