Default Strange Knocking Noise? - 08-20-2020, 10:57 AM

I bought the car with fbo, it drives fine and I don't hear anything. But when I'm idling and rev the engine to about 3k and let it drop back to idle, I can hear knocking noises coming from the bottom of the car and it faintly shakes a bit then it all goes away.

Here's a link to the sound I recorded

Is this the car in your sig? Still on a stock flywheel? Sounds like the dual mass is on it's way out.

Yeah it's the car in my sig, 6mt. I honestly don't know if it's on stock flywheel on it, I have yet to do any work on it since I'm still waiting for parts unfortunately. You think it's better to go OEM or upgrade the flywheel? I won't really be running too much power on it.
