I have had a clicking sound endlessly for months on end with my s2000. I replaced the TCT with a BM Rebuilt Tensioner. Adjusted the valves a week ago. Had honda check cylinders, they used some kind of snake camera and said they looked ok. No matter what i do it continues! Even put stock exhaust on, it was a quieter click, but it was still there. anyone help? ill try n get a vid up soon

 

maybe fuel injectors?

 

Maybe an exhaust leak. Take the black thin heatshield off by the header, and see if all of those bolts are tight. Also get under the car and see if the cat (or test pipe) bolts aren't loose.

 

I would say injectors. It's normal to have some sort of ticking noise from them. Pinpointing the noise using a stethoscope will help/

 

i have weird ass trim issues... both fuels negative... and ive looked at most everything except the injectors... the injectors could click rather loudly? Im going to pull my entire exhaust and redo all gaskets and seals over the upcoming break, but i keep thinking injectors... anyone know of a way i can check?

edit: i noticed it sometimes seems sluggish on start off, and low rpms fuel trim is bad. also, when i was backing into garage today, normaly i have silencers and top up. well i got a test pipe on it now, and no silencers/top. and the thing sounds like a mustang! that muscle kinda gluggy sound. perhaps not an issue, it sounds the same as the day i put test pipe on it when driving normaly, just never noticed the backing sound since i normaly dont back in either.
