    Default "Pinking" knock / rattle

    Guys



    Under hard acceleration i'm getting a "pinking" / rattle accompanied with dead spots as though fuel starved. Smoke level CRD-T fitted )

    When doing it sounds as though top half is rattling itself to bits.

    Only started tonight, had the CRD-T fitted a while now with no previous problems..

    Engine as per signature below..........

    Any clues?????

    Damn iPad....

    Sorry..... The smoke bit should read as :-

    Smokes level increased due to crd-t fitted. However it changes colour greyish to black.
    Black being normal as the crd obviously increases fuel.

    Are you Pretty sure about that? I have a ver of op-com and and had a look at the injector timings this morning after reading another post, from what little I know they should read very similar between them?
    If they need a fix, what's best approach? A take out and clean?

    I've got a bottle of millers to go through to see if helps.

    Injector quantity deviation mg/ stroke readings as follows:-
    2800 rpm
    No 1 : -0.26
    No 2 : -0.18
    No 3 : -0.48
    No 4 : -0.94 also saw 1.26 here.

    Help appreciated.
