Lotus Elise 111S (S2 - Rover K engine, 158/160 bhp) - Normal engine noise?

This sound was recorded shortly after firing up the engine. I missed the opportunity to record the coldstart. However, the recording was made as the engine was still warming up (after a ride of 1 km).
Is this a regular, healthy sound for this specific engine? Or is the rattling something to worry about?
I appreciate your comment. Thanks!

Totally normal. They have a tendency to sound like this :)
