Oil in the 20V distributor implies excessive blow by and/or a restricted CC
breather system. This dist. has no oil seal, just a spiral groove pump on
the shaft, which is easily overcome with excessive CC pressure. At 220K my
dist is bone dry, maybe because of my pieced together, old radiator and
heater hose breather system? Narrowing the rotor tip is a common fix for the
more available 7A rotor.
