I am backing up the below statement. DO NOT use silicone on a cork gasket ever! It will "ooze" out and get into places it DOES NOT belong.Also,It will tend to break the gasket apart.(My transmission buddy knows this TOO WELL!)
My way of doing it: Make sure your oil pan rail is straight.if it is NOT,then either make it that way,or get another pan.(Be sure to get the bolt "dimpling" out of the pan bolt holes. A little work with a ball pien hammer, flat punch on a flat surface works good here.)
Take a SMALL amout/little dabs of something like 3M weather strip adhesive or Permatex "Hi Tack" and glue the gasket to the oil pan's rail,then oil the block surface where the gasket is sealing to the pan.Tighten the pan down evenly and DO NOT over tighten the pan bolts!!!!!
The ONLY time I ever use silicone on an oil pan is like on a BB Chev pan where the cork rail gaskets meet the rubber end gaskets. ONLY in the corners.;)
Was that "long winded" enough???? lol
