    So here I am all happy with the motor it's quieting down, running smooth and producing plenty of power and now today I hear that annoyin whack, whack, whack for a second or two at startup.

    Lifter not pumping up? Right, wrong? Any backyard redneck fixes? I really can't tear into this motor as I don't have a backup vehicle running. Plenty of non running ones though. /forums/images/graemlins/thinking.gif

    Thanks in advance and good luck to y'all in the future.

    What weight oil are you running, if you are running a heavy oil, try a lighter weight, might pump up faster /forums/images/graemlins/dunno.gif

    Wen Ihad ticky lifters on one of my vehicles years ago , a mech. friend of mine just put in a litre of auto tranny fluid
    He said it would free up any deposits causing lifters to stick
    Then change the oil in a day or two
    I don't remember what ATF. he used though.
    This might help /forums/images/graemlins/thumb.gif
    The Ontario redneck method LOL

    Allan.....if the lifter is dirty (if the oil is really nasty) try changing your oil and filter, replace one quart of oil with ATF like was mentioned above, ATF is high in detergent and can help clean out the engine. Change the oil again after its dirty or in about 500 miles. There are other ways to clean out an engine if its severely dirty as well. If the rocker adjusting nut has loosened it would tick at high RPMs and when idling even when the engine is warm. If the lifter is worn you can add a good quality friction reducer (not STP) to help until you can replace the cam and lifters. Not sure what weight oil you use but try a 10W-40 or 10W-30 if you are using heavier than that. It may help the lifter pump up faster at cold starts. Good luck! /forums/images/graemlins/thumb.gif
