Has anybody performed an extensive study on the maximum amount of oil that "can" (not should) be used in a Clone on a 10* mount before the crankshaft starts slapping (whipping) the oil? I've got a crankcase vent in the side-cover that shows NO trace of exiting oil/vapor and a 3/8's vent line on the valve cover (both) going too a secure, well-vented catch can and the valve cover vent is expelling 'lots of whipped' oil (looks like a strawberry milkshake) after 3-4 laps! BTW...my oil return hole is Only 4mm (.158). "Bingo...the light is on"!! Again...this is a '10 degree' mount! Thanks for any input.
