I pulled the distributor on the 78 Royale, and it did not have an oring where it sits in the engine. The way I read the parts book, p.7-16 and 7-18, the old style had an o-ring and the HEI did not. The one I pulled out was VERY stuck/gunked in (I used a steady pull from above with a ratchet strap on the gantry I built to pull the intake manifold, and then tapped with a rubber mallet for nearly half hour. lots of PB blaster). Should I grease and re-install with no o-ring?

1975 Glenbrook, 1978 Royale rear bath Raleigh, NC
