Leaking A904 front seal

I think if you over-fill the oil it will come out the front seal (or look like it). It is easy to over-fill because it is hard to get a good level reading, especially until you get it right. Otherwise, it splashes and churns so you get strange readings on the stick.
Actually Bill,it's been my experience with overfilling, that the churning oil goes out the vent that is also in the bellhouse.So you are absolutely right about it looking like a bad front seal.And there is no test to determine which it is, except to drain some oil and see what happens, I guess.......
