    Default Why can i hear the tappets under light acceleration in my V8,oil is NOT low

    I noticed this small issue lately and cant help but wonder how long its being going on for since i usually cant hear it over the radio.
    The tappets tend to be noisy when starting but goes after a few seconds once the oil get up the top. Could i have a faulty oil pump?

    How long is a piece of string...?

    When was your last oil change?
    Is there enough oil in the engine?
    What sort of engine oil did you/they use last oil change?
    How many km's are on the engine?
    What sort of oil pressure do you have?

    Are you hearing the tappets or the injectors? My injectors are ridiculously loud and it does sound like lifters tapping.

    If it's only when you start the car (and it's been services properly) the it will be a drain back issue probably try a better oil filter.
