[DeTomaso] question - best oilpan gasket

[JDeRyke at aol.com]

To address the original question- what type pan gasket is best, there are 
basically three types. One is a matrix of cork and plastic fillers while the 
other is a synthetic rubber. These two are around .090" thick. A third is a 
thick paper gasket maybe .040" thick.
Over time it's pretty easy to pinch the cork gaskets in two, especially if 
you get a small seep of oil and retorque the bolts to stop it. The rubber 
ones don't pinch in two as easily but they do slide around unless one side is 
contact-cemented to either the block flange or the pan. I've had best luck 
using the thick paper gaskets, but the pan flange must be very straight & 
flat or you'll get instant leaks. Don't ask me for brands & part numbers- don't 
know without rooting around in the shop and that's about all I've done 
recently. My   2¢- J DeRyke
