Bill,

Thanks. That seems counterintuitive--I had assumed that one lip good, two better! The description on the one I fitted was TCI ( I think the T stands for Twin ) " Double Lip with Bi Directional Feature."
Is this what you mean by " One lip in, one lip out"?
I had assumed that the Bi Directional would mean that the seal worked both to keep the sea out and the oil in, but from your comment that wouldn't seem to be beneficial. I will have a look. You live and learn.

Ian and Judy, Pen Azen, SM 302 Greece

Ian,

Two lips?? Did you buy a seal with one lip out and one lip in?

If so, that is the cause of your leak. Research this and you will understand.
