I've had my 2004 S2000 (27k miles) for a week now and I'm currently getting the maintenance up to spec. I've noticed this clicking noise that the engine makes and I'm wondering if I should be concerned or if this is a normal sound.

From what I've read, a bad TCT usually sounds like a card stuck in bicycle spokes and is quite loud. My engine makes a similar noise but it's very subtle and you really have to listen for it. Just want to know if there's something I need to replace before it turns into a bigger problem in the future. Thanks.

Don't notice anything in particular off the top of my head. Does the sound increase with RPM? Would be nice to hear it with you rotating the throttle.

 

The sound does not increase with an increase in RPMs. It stays constant. When driving I can hear the faint clicking noise but it usually drowns out when getting up to higher speed/RPMs.
