Chris,

I think Thomas is referring to the spring/check balls in the crank that
block the oil spray into the rotors at low rpm.  The purpose of the oil
spray is to cool the rotors.  To my knowledge, there is nothing that
inhibits oil to the bearings, unless you consider the pressure relief valve
as doing that, but it only controls high pressure.

Mark
