First thought it's the vacuum pump but can't hear the noise coming from it. Unable to track it really.

Symptoms:
1. Only can here the ticking noise inside the cabin
2. Starts about 2 minutes after cold start
3. Comes and goes. Can increase in frequency at same rpm.
4. Blip the throttle to 3k rpm and it goes away. Then comes back.
5. Only get the tick at idle
6. Not constant. Comes and goes.

Could be worn chain guides producing chain slap?

The tick frequency increases at times at idle and the tick goes away. So can rule things like chain slap out.
