    tapping....

    astra coupe turbo with the z20let....starting tapping last night, oil is fine, full etc etc checked the usual things sound like tappets but when the bonnet closed it sounds like it coming from the rear of the engine.

    sooo had a look at it this afternoon and the two middle injectors sound really loud.

    runs drives well not problems no lights etc etc.

    shoulf i worrie? is it just the cold taking its tole

    As said you sure it's not carbon canister just behind airbox as that taps usually when engines stood still and warm
