distributor

[herb s]

The distributor in my 1995 900 is leaking oil into cap and onto wires. Do I have a problem with O ring or is their a problem within the distributor? i.e. the shaft is allowing oil to flow by Is their an easy fix or do I need new distributor?

Thanks,
Herb

Other than the bolt you see in the mounting flange there on the side of the head under the distributor itself, the distributor is clamped into place with a collar with two(2) torx screws located inside of the valve cover.
However, leakage around the distributor indicates a fault in your "positive crankcase ventilation system" (PCV).
I'd suggest removing the PCV nipple there on the back, left-hand side of the valve cover, remove the small and large diameter hoses (checking them for residual oil deposits) and cleaning it out with some "brake wash" parts cleaner and a small "bottle brush" and a thin piece of wire (for the smaller nipples channel).
Replace and reconnect everything and see if that solves your problem.
