Our team of technicians has developed a Rear Main Seal that corrects the notorious rear main oil leaks on the m96 and m97 engines. It has been developed to solve the twisting of the last journal of the crank shaft, reducing engine vibration and extending engine life. Prevent engine failure, by replacing your factory rear main seal with our upgraded rear main bearing seal and housing.

Features:
• prevents crank warping
• decreases engine vibrations
• prevents piston rod #6 failure
• extends engine life

NOTE: For The 2001 Model Year, Porsche Replaced The Intermediate Shaft's Roller-Type (Duplex) Chain With A Tooth-Type Chain. This Listing Is For The Later Tooth-Type Chain And Is Not Compatible With Earlier Engines Equipped With The Roller-Type Chain.

While Unlikely, It's Possible That An Earlier Engine May Have Been Rebuilt And Upgraded To Use The Newer Chain Design. For This Reason, Design 911 Strongly Recommends Confirming Which Type Of Chain Your Engine Uses Before Placing An Order. To Assist With Identification, Our Product Images Include A Helpful Comparison Between The Roller-Type (Duplex) Chain And The Tooth-Type Chain.

NOTE: For the 2001 model year, Porsche replaced the intermediate shaft's roller-type (duplex) chain with a tooth-type chain. This listing is for the later tooth-type chain and is not compatible with earlier engines equipped with the roller-type chain.

While unlikely, it's possible that an earlier engine may have been rebuilt and upgraded to use the newer chain design. For this reason, Design 911 strongly recommends confirming which type of chain your engine uses before placing an order. To assist with identification, our product images include a helpful comparison between the roller-type (duplex) chain and the tooth-type chain.
