I've noticed that my car clicks, at Idle at low RPM and low Injector Duty the clicks are fairly slow, but they increase when I rev it or accelerate. I'm trying to figure out where it comes from, it sounds like from under the UIM or on the exhaust side, but even when driving i can hear them its only at lower rpms (well and if the radio is off and the window is down) because eventually the clicks get so fast everything kinda meshes together at higher rpms lol , so guys any ideas? Oh i searched around and most of the click related things that came up when i searched were related to the "click,click,start" problems

 

I would hazard a guess at the injectors, but its kinda hard to be sure. Tell us about any mods to the car that have been made so we can narrow down some possible suspects.

 

As far as mods go i have intake,full exhaust (with resonated midpipe), SMIC Blitz intercooler, and PFC with the base map tune from rx7store.net. Also, i have the air pump disconnected.

 

My guess would be a small turbo manifold gasket leak, or possibly your collector gasket.

 

I would check the compression on the engine. I had a strange click on one of my SE's once and thought it was just the clutch weights(centerforce) pulled the trans and swapped it out and it was still there for about 10 min then lost the front rotor I can only assume it was a cracked apex seal and it clicked as it went over the exhaust port.

 

The engine is pretty new, has about 4000 miles on it, i thought it might be injector click, but im not sure. As far as collector gasket goes, i'll check that out this weekend when im installing the new radiator. I'm praying its not a cracked apex seal seeing as how its a brand new engine, thats never been overboosted or ran too hot, or even lean for that matter, ill try to post a video so you guys can hear the sound

 

not sure how to embed a video in my post =\

You can hear the clicking sound the best when the camera is above the UIM imo

 

Could it maybe, be spark arc?
