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.

Is the smoke white or blue? If white means that you have a leak of water or antifrezze into the combustion chamber. If blue, replace PCV valve, and air filter.

check the fuel regulator vacumn line,if its getting vacumn then maybe the regulator is bad,which cost about $55.00

i have a simialer problem but i was getting neat fuel out the exhaust as well . i removed the engine because id got a replacement then stripped the old one and as i thought it was a valve timing problem.looking at the engine from the front the cams on the left bank had jumped one tooth out of time so fuel was not being burnt and coming straight through the exhaust.strangely it didnt seem to have a big missfire and idling and smoke got worse when warm.

White smoke means that you have a coolant leak. Two possible causes for that - either the head gasket is punctured and must be replaced or the head itself is damaged and must be welded by an expert. 
Either way the engine must be dismantled to make a full diagnose and repair.
