I just did the quick fix on mine yesterday as the "pinhole" had developed, right where I heard it would.. Slapped some JB weld on 'er, waited about 6 hours and layerd hi temp silly cone on it too.. Only drove around town so far, no leakage.. We'll see though, I havent worked it yet.. Gonna likely have to do the rear case half sooner or later..
Do you guys know these pin holes from the oil filter clips where in the other indexs, or just the lower right rear that is common?

Thanks
