The factory at some point came up with an upgraded gasket and bolt design to
fix this. The cork gaskets don't work especially after the pan is over
tightened and distorted just once. Most of us now just use a filler gasket
such as the "right stuff" for this job. There are also silicone type
sealants designed for rear axle/differential lubricants.

If this is a failure over time look for possibilities that something is
overheating. Heat will also destroy gaskets and sealants.

Subject: Differential Pan Gasket

My mechanic is about to replace the Differential Pan Gasket for the 3rd time
in less than a year (12,000 miles since the first)    Any suggestions on
which gasket to buy, or which sealing goop to use?    1990 Westy, 2.2 Liter,

Thanks
