    1975 Blazer smoking.

    1975 Chevy Blazer starts up great,...
    but after a few minutes it starts pushing out light white
    smoke out of the exhaust.
    Autozone told me to pour some
    'Smoke B Gone' in it and that should fix the problem.
    I wanted to ask you all what you think,
    before I do anything.
    Thanks.

    i drained the oil and there was no milky
    discoloration in the oil....it looked totally
    normal. i thought the same thing at first.
    is there another way of double checking this,
    just to make sure.
    i mean if the oil is fine, could that still be the problem?

    may be coolant seeping into the combustion chambers only when it gets hot?

    sounds like time for a rebuild. white smoke is burnt oil. There's no liquid fix for oil consumption

    if coolant was seeping in, only when it was warmed up,
    wouldnt the coolant also end up mixing with the oil
    and wouldn't i still see a discoloration in the oil when i drained it?
    its not thick smoke, just light enough to look abit hazy.
    i guess i'll try that Bardahl-'No Smoke plus Stop Leak' stuff
    they have at Autozone for now.

    the way i remember white smoke=bad head gasket blue smoke=oil burner black smoke=running with too much gas
    i could be wrong about this but i'd go with new head gaskets valve cover intake gaskets etc if they haven't been replaced for awhile and while the heads are off check the cylinders

    How long does the smoke keep comming out? Its possible its just steam comming from the condensation that builds up in the exhaust while it sits..
