oil on the good foot

[bikerphil]

Hey Eric...

Yes, there is an O-ring that goes on the left side oil galley plug which is located directly under the ignition cover. The one you listed above is the correct one. It could be the source of your leak, won't hurt trying that first. If you want to save some time and money, go to your local hardware store and ask them for a #14 O-ring which is the proper size. When replacing, take care not to over tighten that plug, they will snap off rather easily, the plug is very cheaply made.

I hope that the O-ring is the problem, that is an easy fix.

This one?

Your original post said the leak was behind the vacuum advance (left side)

That O-ring goes onto the oil galley plug on the right side.

Edit: Thanks bikerphil for correcting - apparently there is another O-ring on the left side as well

There's a plug with an o-ring. I should try that first. Right under the cover, it might be leaking from there.

It took me about 30 minutes to get this seal out...

Thank you. I'm studying whether this is a job I can do without breaking something or if I should ask the mechanic here.

I just did one of these crankshaft seals, it is a real pita getting the old one out. The seal has a lip on it that rides in a groove. You really have to destroy the old seal to remove it, trying not to gouge the aluminum case or scratch the crankshaft. The replacement seals don't have the lip, so installation is a breeze.
