The front cover uses a large O-ring type of gasket, but I've yet to see one leak. Are you sure that is the source of your leak and not the weep hole?

No, the weep hole is on the lower side.

I replace some gaskets on a 94 where the pump meets the cooling passages in the block, it was leaking there. 4 bucks a piece and my time, good as new.

Hi,
A leak on the top of the WP could also be from leakage/seepage around the top boltholes.
