    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.

    Originally I thought it was related to the oil and it was overdue for an oil change. Changed the oil and filter, the same noise.

    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

    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.

    Now that I know the problem, should i just replace the racks?
    Brand new vs refurbished?
    Should I also change the pump?
    Should I also change the hose?

    There is only one rack, reconditioned will be fine. Brand new will cost a fortune.
    It recommended to do the pump as well, reconditioned will be fine, brand new will be affordable.
    No need to change hoses unless they are leaking or perished.

    How bad is the leak and where? You can pick up a recondition one on Ebay for around 250 mark, my mates vt s2 rack was quoted 800 at a mechanic to supply and fitted, if you do change it out count the turns until both tie rod ends fall off and write both down so when replacing them you can roughly have it close to the alignment, but have it done after fitting the new rack.

    Noisy lifters are very common with a high klm V6's a not no real concern.
    Thanks to someones recommendation in here we started using the Nulon high klms 20/50 oil and the Nulon noisy lifter additive and now at start up the noise lasts 3 second and then returns to its lovely operating musical.
