Bob....As with most repairs, make it as simple as possible. Since concours
judges seldom check threads inside distributors, drill and tap to suit
whatever appropriately-sized screw you have available.
If the bushings are still reasonably tight but you are getting more and more
oil in the distributor, my guess is you are pressurizing the crankcase more
than you used to. Sounds like the piston rings may be weakening, or else the
crankcase breather is plugged. Try a can of Restore in the oil - we've found
it really does help restore compression where cylinder bore or piston ring
wear is the reason for the drop.
As for the Pertronix, we recommend them as an excellent fix for worn-out
points-type distributors. We have not experienced any problems with
Pertronix ignitions.
