It's a sure sign of old age, but does not indicate an impending
failure. But with that many miles I would reasonably expect to replace
it in the next year or so.
If it is on the alternator body the residue is probably just aluminum
Is there any chance you are losing anti-freeze? It has been
my experience that a steam leak from the cooling system will
discolor aluminum parts. Is your alternator uniformly white,
or splotchy? I'd make sure there isn't a leaking hose, or
loose hose connection in the area of the alternator.
Hint.... the brushes are likely near gone.
order a replacement brush set, take it off this weekend and replace the
brushes and check bearings, lube the rear one.
look on google this group for tip on refurbing alternator.
If 3.0, remove the overflow/washer tank and set aside, loosen tensioner pivot
bolt. swing tensioner with breaker bar or long box wrench, Slip belt off
idler, totally remove stamped bracket between intake and alternator boss.
