4.2 diesel turbo 12 valve - rattle under full acceleration at around 2300rpm sounds valvey then goes away? (1 Viewer)

[Benz]

Hi All
I have owned an 80 series diesel for 20 years with 560k now and never any trouble but in the last year or so i have noticed a valve train type rattle when under full acceleration at around 2300rpm and only under full throttle with turbos whistling etc, any ideas would be appreciated.
thanks
Ben

May have some more input in the diesel section on here. Most the 80's in here are gassers with the 1fzfe or 3fe.
