Our team of technicians has developed an exclusive pattern pending solution that corrects the notorious rear main seal oil leaks on the m96 and m97 engines. This solution adds an addition #8 bearing and housing to the end of the crankshaft providing additional support, reducing engine vibration and extending engine life. This product has been designed to solve the twisting of the last journal of the crankshaft.

We recommend using this part in conjunction with the IMS bearing. 

The Rear Main Seal comes with an installer tool.
