I have a 1966 122 Amazon on which I recently completed a major rehab (fuel and brakes lines, brakes, body, interior, gas tank, clutch, front end, full motor rebuild, starter, generator, carbs, etc). I replaced the pinion seal in the rear end but was getting a small amount of leaking so I replaced it again and I'm still getting a small bit of leaking. I checked to make sure I was not seeing leakage from the gasket on the rear end cover and it appears that the leak is definitely coming from the pinion seal. Questions: is it possible/likely that there is some sort of gouge or ding in the race where the pinion seal sits that is allowing oil to leak ? I didn't detect anything significant when I installed the new seal but who knows. If so, how would I correct that issue? Someone suggested I apply silicone sealer to the race and then insert a new pinion seal. Does that sound like it might work? Any other suggestions? It kind of sucks that I rehabed the whole car and I have to put a piece of cardboard under the rear end to absorb the small mountain of oil that leaks from the pinion. Thanks for your suggestions.
