Remember that with some of the Nissan Diesel engines that they are Chain drive and this tends to rattle some times.

no chains on patrol engines, well not ones i've dealt with anyway.
The TD42 in question here is gear driven,
the RB30 petrol and my 2.8 TD are belt driven,
not sure on the ZD30? :undecided:
