This is for my '89 Trooper with the 2.6 engine.

I have too much oil on the underside of the engine. It bothers me. I looked up from underneath and saw a rather large drop of oil hanging on the bottom side of the distributor. Could this be the source of all the oil on the bottom of the engine and transmission?

I have a vague recollection that there is an "O" ring on the distributor shaft. Presumably if the O ring is damaged it will leak oil. Would there be any other affects? Would it in any way affect how the distributor turns, how the engine runs?

What size O ring do I need to replace this with? Can I get one at Home Depot, or do I need a special automotive quality O ring, one which will hold up to the hot engine oil?

Thanks for any and all replies.
