Thanks so much for posting this, I bought the last of the Utes to come to NZ and started to notice a cold knock/rattle at around 18,000km. I have now done about 21,000 in a year and a half, am totally disappointed and it seriously takes away from the joy of driving. I am still discussing the noise with the Dealer and was looking forward to a track day having treated it to a long trip on collecting it to run it in nicely, some short running but mostly it has 160km highway trips away each weekend, only use 98 octane from BP or Gull, use Mobil 1 with dexos2 at half the specified time frames, and I’m pretty easy on it from cold. The noise is prominent as revs approach 2000 rpm and at 2500 when it changes gear is a dull rattle/knock and once warm is gone. Not sure what I will do now as I love the warmed up driving experience and as an investment in a driveable classic it’s not really anything that I expected.
