Changed out the O-ring on my 2000 4cylinder and it's still dripping oil. I saw in a previous post that it could be coming from the area where the distributor blade goes into the head. How do you seal that area?

 

I believe that I found my problem, the O-ring was the wrong size. Apparently, there are more than one size of O-ring for the distributor. The one that I installed only fills half of the channel. I'm going to buy a new one from Honda tomorrow. I'll let you know how that works out.

 

Success! I stopped by AZ tonight and picked up a O-ring assorted pack. Found an O-ring that fit perfectly. I let the car run for 15 minutes after install and left a paper towel under the distributor. No leaks, drips, or errors. Thanks again guys, another completed task.
