the camshaft seal failed on my fester, with the oddity that i can actually see a small section of the camshaft rotating, i.e a quarter inch section of camshaft at the end has been exposed where the seal has disintigrated.
i am not sure how long the camshaft has been exposed. but i was hoping to just renew the failed seal.
if the camsaft end got scored by dust/dirt, would it destroy the new seal? any other problems from a scored camshaft end? thx
