Default 1991 4 cyl camry oil leak question

Oil leaking from the timing belt cover.
What possible sources could be leaking into the timing belt area?
Thank you,
Seamus J. Wilson

Camshaft seal(s), crankshaft seal, and oil pump seal and o-rings can all
leak oil into that area.

The trouble is I found, is that once one seal starts leaking, the others
aren't far behind it, plus the cam-belt has to come off. In view of that,
its expedient to replace the belt and if the waterpump has big miles on it,
do it as well. On Camrys the w/pump is driven off the cam-belt.

Is the oil pump driven by the timing belt in this model? could it be the
source of an oil leak?

Yes it is, and it can also be a source of oil-leak. It has a shaft seal and
a formed "ring" made of neoprene to seal the pump-pressure from escaping
between the pump front-plate and its housing.

One of the consequences of too few oil-changes is hardening of all shaft
seals. Something to do with the impurities in the oil. On mine, the OPump
shaft seal cut a deep groove into the pump's shaft. A new pump was about
$170
