    Grab a good heavy glove.....With the engine running...WARM...Place your gloved hand on the sheet metal shield on the turbo and see if this makes a difference in the noise......

    I have seen these shields radiate a metric buttload of noise...
    Easy to fix....Bolt on a strip of 1/4" flat lead to deaden the noise....

    The injectors and the regular diesel rattle gets picked up and radiated by the shield.

    My bet is a firm gloved hand on the heat shield will kill the noise....
