OEM Valve Cover Gasket Ring – Compatible with 900 123 144 30 Engine Seal

Description

Cam/Valve Cover Sealing Ring
This washer/sealing ring was added under the head of the bolt as a Porsche Bulletin.
This allowed the cam cover to be pulled tighter to the head and provide a better seal.
The bulletin stated to add the washer to 13 of the bolts but it is better practice to add them to all 26 bolts.
