| You need to get the oil out of the crankcase so it does not interfere with motion of the crank and cause the heating problem in the first place. \\ | You need to get the oil out of the crankcase so it does not interfere with motion of the crank and cause the heating problem in the first place. \\ | ||
| - | The proposed approach is to bleed off excess high pressure oil from the feed side of the oil pump. \\ | + | Some have found it useful to build bypass circuits to bleed off excess oil pressure and send it back to the tank. \\ |
| Such that the scavaging side of the pump will be able to evacuate the oil from the crankcase before it starts to wet sump and generate the added heat. \\ | Such that the scavaging side of the pump will be able to evacuate the oil from the crankcase before it starts to wet sump and generate the added heat. \\ | ||
| + | But this does reduce oil pressure across the board, as opposed to opening a bypass when the pressure exceeds a certain point. \\ | ||
