    Hi Guys,

    I've got a bog standard 90bhp T reg 306 HDI.

    When under heavy load, eg foot to the floor up a hill at between
    1500-2500rpm, it makes a noise that can best be described as the noise you'd
    get from a petrol engine, when it was pinking.

    But obviously, being a diesel engine, its not pinking...

    It only does it when under heavy load, and as soon as you lift off the
    throttle, the noise stops.
    Its not a loud noise, and cant be heard at all when in neutral, bonnet up
    style.

    Could be my imagination, but I think its worse when the engine is cold.

    Other plausible suggestions were the injectors, or the fuel pump.

    Anyone got any ideas or similar experiences?

    Much appreciated,
    Ed
