Idle engine sound?

[moka]

Anyone have a recording of what the engine sounds like in idle, such as when put into maintenance mode?

Searched in the forum but no luck finding it.

I changed oil today and heard some clicking noise from the engine. Not sure what normal sounds like.

I'll record it tomorrow and post.

If you’ve ever heard a modern vehicle with an inline 4 cylinder engine idle, it sounds like that.

Here are the engine sound recordings.
1. Engine cold. Sounds normal. https://www.dropbox.com/s/sr84w0ek2vzlkxg/Clarity 1.m4a?dl=0
2. Couple of minutes later. Clicking/whisking sound. Engine still cold. https://www.dropbox.com/s/5gbg01tmj7kc83w/Clarity 2.m4a?dl=0
3. Engine warmed up. More clear clicking/whisking sound. https://www.dropbox.com/s/lncehn0q9l9antc/Clarity 3.m4a?dl=0

These are recorded with the hood open. Almost no clicking/whisking sound with the hood closed.
