When I start the engine, there is this noise that start a bit louder and as the engine gets to normal operational temperature it becomes much less noisy.
Drove the car for some 15 km and i almost did not hear that noise at all?
What is causing this issue?

Does it sound like a tick or tap that increases and decreases with revs?

Perhaps a lazy lifter? What oil are you running?

Could be a Water Pump, Alternator, Pulleys, that quieten down when they get to Temperature.
Check the hardware with a mechanics stethoscope.

Thanks krusing. I just don't have one!

You can use it for all types of diagnosis,
Pulleys, Hardware on the engine [water pump], Lifter noise, noisy inlet/exhaust valve, the list is endless.

I had an unusual noise on my Super6,
and purchased one, and found 2 pulleys were the cause, and then realised the Supercharger Snout and Blower Bearings were also noisy,
I would not of found that out without it,
And now it runs so quiet when krusing [cruising].

Where the link I provided is a much cheaper than what I paid,
But looks exactly the same.

All the doctors in the world couldn't be wrong :D

vs commodore
Can you pin point the area? Most high k's engines tick when cold, carbon build up or sludge or wax or varnish deposits causing sticky/noisy lifters, they do have additives to help clean / break down the carbon that you can add to oil, and they say using 98 octane has more cleaning agent added to also help break down carbon on valves.

I give my pulleys a spray with wd40 if the noise fades you found the crook bearing. Might not be the correct way but it works for me.
