VDJ79 V8 4.5 LTR CLATTER WHEN COLD

[pchatz]

Hi All - I have a 2009 V8 4.5 ltr Diesel Landcruiser . Has done just over 200kms - When I start it cold it starts and idles/revs ok no noises , but when I drive off ,as revs get up over 2000 rpm the engine makes a clattering sound . It has gotten progressively louder over time . Once it is up to temp it sounds ok and will run all day with no issues. It only does this when cold. Have done regular oil changes with good quality oil . Doesnt get a hard life .Anyone else had similar issues or can offer advice please? Cheers
TO ANYONE WHO IS INTERESTED - THIS CLATTERING IS COMMON AND INDICATIVE OF WORN INJECTORS .TRUCK HAS TRAVELLED 202000KMS ON ORIGINALS SO APPEARS THAT IT NEEDS NEW ONES.
