I have a s2k and i hear a very quiet and i mean quiet click from the the engine bay and its not a consistent click. You really have to try to listen to it to hear it. I was wondering is there anybody from vancouver or portland that owns a S can listen to my car or compare it to there car to see if it is even a issue? lol just trying to baby my car I'm thinking it might be a tct but its not a consistent click and its way to quiet to be a rod knock?
