What Is the 68079589AA Crankshaft Oil Seal?

The 68079589AA Crankshaft Oil Seal, also known as a rear main seal, is a rubber and metal gasket that seals the crankshaft where it exits the engine block. This vital component is designed to:

• Prevent engine oil from leaking around the crankshaft

• Maintain internal oil pressure
