Question about Hyundai Accent
White smoke or semi white can be produced in several ways. One way is
oil this is normally a whitish blue to blue smoke and has the apparent
smell of oil being burned. Next could be antifreeze when it is being
burned it has a sweet type of smell and tends to dissipate in the air
rather quickly and usually is because of a bad head gasket. Next is automatic transmission fluid which is normally
found on automatic transmissions and its normally drawn into an engine
thru a vacuum line via a defective transmission modulator valve or some
other defective part. Transmission fluid is very apparent and billows
out so bad that you can't see anything behind you. Last but not least
another type of smoke that is not white but black is the presents of to
much gas/fuel being burned in the engine. If one of these fluids is low and/or you notice one of the symptoms that I pointed out above, then you know where to start looking for a fix.
I would also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

SOURCE: I have a 2007 Hyundai
White smoke during startup is indicative of a blown head gasket and/or cracked cylinder head..
Have the cylinders pressure tested to verify.
Do not use engine additives to try and stop the leak. They do not work.
