993 RS/Supercup Through Bolt O rings
The 993 RS uses O rings on the bearing webs as shown below in FSM.
O rings in this position are also used on 993 race engines and GT3 as well (GT3 uses different O ring and has a square cut recess) and they are supposed to damp through bolt vibrations that can lead to failure as here: Through-bolt failure 993 Supercup - Rennlist Discussion Forums The part number for the O ring shown below: 999.707.288.40 is the same one for O ring that is inserted between the plastic oil bridge and the chain housing oil gallery on 3.6 and later engines. Question: Has anyone machined the bevel required for these O rings and what angle bevel and how deep? [IMG]  [/IMG]
