Still am trying to find out what this sound is. Intermittent clicking every 1 second after cold start from the driver's side of the engine. Goes away after its fully warmed up. I don't think its fault or problem with the engine, just trying to find out what it is. Some have suggested that its the engine block warming up, I disagree. It only comes from one spot on the engine.
