Thanks again for your help pdgizwiz. I think I finally understand the whole distributor issue and it's good for me that I understand now. I feel better about it all. Since I have changed the valve cover gasket and the distributor O Ring, my oil leak is very small so not much of a concern really but I wanted to fix it.

I just used the last of my Toyota A700 wiper blade inserts this year. I saw a video somewhere on how to use other inserts to replace them and plan to try that method when the next replacement time comes.

I sure appreciate your help...
