    Slight ticking from engine S4 B5

    It sounds like the exhaust have a slight leak but I don't think it's that. Seems to be coming from the drivers side middle of the cam. The fuel pressure regulator is ticking away s oI woder if it is that but it's hard to listen for anything else when all I can hear is the FPR. Are they generally noisey or just when they're failing?

    Injectors generally tick, but you only typically notice them when your listening closely at the engine.
