Change the pan if it rusted through in one spot there will be another.Joe.F has an autolibrary link that will give details on replacement.

You will do yourself some justice if you pick up a Chiltons service manual as it has this procedure in it and also the proper tightning sequence. Try your local library or maybe www.automanualtrader.com on the web.
