    Watching one of many car restoration/build shows on Discovery Turbo .... "Texas Metal"
    They had an old 1949 International water truck to convert to a mobile bbq wagon (yee hah!)

    Well they had the eternal expert old guy in to start the motor ..... bit of starter fluid and no go and it backfired .... so he says "stuck valve' .... out comes the transmission fluid to 'free up the valve' and a few hundred mls down the carby ... more starter fluid and bingo .... roars into life

    interesting method :cool:

    Seen that done before, a mate had an old XB Falcon that he bought off a farmer the engine had a miss.
    Mate suspected it was a sticky valve so poured about half a litre down the carby while holding the throttle open at about 2500 rpm's.
    It sucked all the trans fluid through and blew ton's of stinky smoke for 5 min's or so.
    After he let the throttle off and it came back down to idle speed again, it had no miss.

    There's something amiss in that procedure, like taking out the spark plugs, cranking it over, put the plugs back in, then start it. Hydrau-lock?

    Nope, it works. These are relatively large capacity engines and there isn’t enough fluid to hydraulic the engine....it’s not a lot different to giving it a dose of redex ( if anyone remembers it)
