The guys I know who have had wrist pin problems are spinning the vacuumn pump faster than 1/2 crank speed and using dry sump systems in some cases they need to disconnect the pump during warm up.
They also with wet sumps see a reduction in oil pressure due to the reduced inlet pump pressure.
I have had no such problems.
Putting a vacuumn pump will reduce and or elimate almost all of your oil leaks, however the vent on the oil breather tank will mist a little oil when the oil is hot, it's no much but to me it's a little annoying.
I too use the felpo crank seal.
