    When changing my plugs & wires I discovered a little pool of fluid sitting on the intake manifold under the carb. I am GUESSING that it is gas leaking from the carb. I am planning on having the carb rebuilt in early June. Is there anything else it could be??? I didn't think it smelled like gas, besides wouldn't gas evaporate?? /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/confused.gif

    Coolant maybe?? I know some gm cars had a coolant line hook up to the carb or throttle body.

    I'd say taste it, but if it is coolant, that could render you dead...

    Is it oil? Not sure if it's "typical" for Chev's to leak that way, but it is on Oldsmobiles, the oil can "migrate" up the intake bolts if it sneaks past the "turkey tray" (full lifter valley/intake seal)

    I've had a couple of small blocks that would have a puddle of oil show up on the intake manifold. Removing the intake bolts and putting a dab of Form-A-Gasket #2 on the threads, then reinstalling the bolts fixed the problem on both. /forums/images/graemlins/cool.gif

    put your finger in it. smell your finger. rub your fingers together, do not dry them off for about 5 min.
    if it smells like fuel and dries off by itself leaving your skin dry its fuel. if it leaves your fingers greasy then it oil. if it smells sweet its anifreeze.

    if its fuel, check your carb and fuel line for leaks, oil, make sure your distributor has a gasket on it, cooland check your intake for cracks and not being sealed to the heads right.
