Thanks again PDGIZWIZ... The picture you posted with the distributor on top of the picture and the distributor gear with the hand on it on the bottom of the picture just posted real good and I can see it better. The O Ring part number 90099-14091 is the distributor mounting O Ring. You put that on when you are ready to push the distributor back in the hole. I've changed this one a few times.

I think I'm understanding incorrectly but I thought based on the picture with the guys hand that there was also an O Ring on the shaft just behind the gear. And I was thinking replacing an O Ring here would stop the oil leak I have that is getting oil inside the distributor cap. But I think I'm seeing this wrong and now think there is just one O Ring that seals the distributor when it is mounted.

Tim said in another post that sometimes oil leaks from around the shaft of the distributor but when this happens the engine runs rough. That would mean to me that the bushing or whatever supports the distributor shaft is worn and the shaft is wabbling... But my engine is not running rough. So I'm wondering what to do to stop the oil leak that is leaking oil into the inside of the distributor cap. I think people are saying you just need to replace the distributor when this happens. Is this correct?

I have another question that I've always been curious about. What is the purpose of the two short hoses that are connected to the distributor. I used to think they were cooling water hoses but don't think that now since they are never very hot.

Thanks for all of your help. It's getting pretty hard to get parts and information for my car now. I broke the clip that holds the hood rod up when the hood is down and went to the local dealership to get on and they laughed at me.... I had the part number and they were able to order one and it is sure better than the ultra hard 32 year old clip was. But it is not too easy to get parts anymore.
