So I have an issue which has always been present with my z. This is present in my engine I'm not talking about the axle click. I just never thought anything of it. Bought with 30,000 miles and previous owner was an older gentlemen.

At idle there is a rhythmic click or something about every 30 seconds or so. This is while I'm parked without the clutch in. I will have to see if it goes away while the ac is on.

Has any other user experience this? I always change the oil on time, it's never low and always use 93 octane.

I can try to get a video. it sounds like it's coming from the bottom driver side.

From my research many people say it's the dual mass flywheel or fuel damper.
