With these catalytic converters we have today you won't see much smoke - if there is no leaks, the only way it could go is burning in the engine due to worn piston oil rings or valve seals.

it could also be leaking into the radiator system take off the cap when its cold and look at the antifreeze. cause would be a bad head gasket or it can bee leaking into the cylindrers does the car run or idle rough, get a compression test. ed k.
