UK owner - High Rpm Rattle

[Elementad]

Hi all

UK owner here whos been reading this forum for a while and finally got round to registering.

I've owned my 370Z since July last year and love it to bits.

I've noticed a rattle noise though and wondered if anyone on here has had similar. I HAVE been using the search tool but most of the rattling threads seem to be concentrating on rattles at low revs or when vehicle is still. (that rattle I've no problem with as my last car (S2000) did that also so consider normal).

I was on a spirited drive in north Wales on Friday and whilst accelerating hard in 3rd gear, when I got to the higher end of the revs I heard a slight rattling similar to the kind of clutch rattle that you get sometimes when vehicle is stationary without clutch being depressed.

The car was performing brilliantly, is a completely standard (non modified) manual 370Z GT, car is not abused and mileage is about 7000. It took about 1.5 hours to drive to the location of our spirited drive but it's not linked to oil temps or anything as UK temp at moment is approx 10C and oil never went above about 103C.

Im sure it's nothing but thought I would see if anyone else has heard similar?

I took the car out yesterday to try and replicate the sound again but it didnt seem to and again ran like a dream - this time without the said high rpm rattle.

Anyone else know of similar rattle at that kind of rpm/gearing?

Thanks in advance

Cheers

Adam
