1972 - 350 SEL Fuel Injection Trigger Points
 

The fuel injection trigger points within the distributor keep oiling-up, I have tried relieving the crankcase pressure by removing the wire mesh filter on the rocker cover but I still need to clean the points at least once every two months. Any suggestions?

The seal in the bottom of the distributer is replaceable. The trick will be to find one, and maybe getting it apart.

I seem to remember using a shift shaft seal either from MB or Volvo.
