A flywheel housing adapted for use with an engine. The engine has a cylinder block and the cylinder block defines a mating portion. The flywheel housing has a groove with an elastomeric seal disposed therein. The groove has an arcuate portion and a pair of leg portions and is in sealing engagement with the mating portion. The principle use is for flywheel housing made of aluminum, however any flywheel housing that has thermal stresses or encounters vibrational loads will benefit from this invention.
