Rattle

[runner911]

As already mentioned in a previous thread , my 2021 McLaren GT was delivered last Thursday . The car has covered just 5000 miles and is mint .
Yesterday however I noticed that starting from cold the engine rattles for about one second and then ticks over normally .
The car drives fine and the rattle does not occur when the engine is warm or hot .
I had a BMW i35 at one stage and the engine exhibited the same symptoms .
Is this normal on a McLaren 4 litre engine ?
Is it just a matter of oil being pumped up to the cam gear from the oil tank etc ?

Would it be easy to record the sound of yours from cold and compare this to the sound of another from cold at a dealership ?
