    Alex[FM] has alredy changed his, but your knocking could be the damped crankshaft pulley. The rubber that provides the damping can fail causing an odd knocking noise, especially on start.

    My old damper I send to one guy, who made some work, and after that I could change bearing in that part.

    On my old demper - rubber like new, only bearing destroyed.

    Usually they fail when the two parts are not joined by rubber anymore.

    But before that - they start vibrate, because of worn out bearing, and if you don't feel it - then start destroy rubber joining

    Sometimes I'm sure that is true. On the other hand I recently changed one where the bearing was fine, but the rubber had come away all along one circumference.

    Update: I changed the injectors to used ones instead of the refurbished ones and the knock is gone...the used ones has roughly 160.000km on the clock.....

    Refurbished injectors:


    Used injectors


    Same condition, fuel temp ~70°, water ~coolant 90°

    Glad you got it sorted but a bit disappointing that the reconditioned injectors are no good.
