I have a hard time believing this noise is anything serious. If a bearing was faulty, wouldn't there be other symptoms, like rough idle or loss of power or something?
God I wish I had never looked at this thread...
Dont worry about that. I think those are just the injectors. The S65 is a relatively "noisy" engine emantling mainly from the valvetrain area. If the sound is emantling from the bottom end of the block, then its something to worry. Take it easy. I really think its just the injectors.
