Your distributor is leaking oil where can it be coming from because you've try to change the distributor but it still leaking?

This could also be caused by a clogged PCV system which is common on these cars especially the 7mge. Pull the oil fill cap with the engine running.

If you have much blowby it will push oil out of anyplace that doesn't have a positive seal, that could include the distributor shaft. If you have that much blowby, the rings are worn and the only option is to rebuild or replace the engnine.
