Need help to diagnose this clunking noise (video inside)
 

1994 manual rx7

it happens at idle and i can hear it more inside the car and i think forward under the car. you cant really hear it in the engine bay.

its a little bit dark out but you can hear the noise clearly

anyone! :P

Does the intensity, frequency and loudness follow the rev-curve?

Is it the same during idle, in gear but clutch in?

heres another forum member with a klonking noise.

I'm pretty sure when I push in the clutch pedal the noise goes away

I don't hear it well driving only well I'm stopped and in neutral and after driving for a bit

It sounds like it could be coming more from the transmission but I can't pin point the exact location

Also it doesn't do it all the time.

My friend said his is doing close to the same thing and he thinks it's a clutch barring on his. Were gonna get together tonight and compare clunks lol

His jeep *****

sounds the trans to me but could be anything

clonking like this should leave some sort of leftovers if its in the gearbox/bellhousing/clutcharea... if you can, lift car and open inspectioncovers on the transmission(two covers that sits on the bellhousing), and check to see if theres any metal spoons there... or, to see if anything rubs, or if the sound intensifies. Start the car on the lift and open covers. :)
