high temp resistant to oil gasket...
when opening up the oil sump make sure you loosen the bolts one by one at opposite corners.. to avoid too much force in one corner and to avoid twisting the sump.. even slight distortion in mating surface will give you a permanent leak..
good brand silicon gaskets that can be used are 3bond, honda bond, loxeal, dow corning, (bossil cheap), devcon, permatex
stay away from that silly black general ki rtv silicone...
