white smoke does not always mean oil. Where is the smoke coming from. Sometimes small pin holes in the water system can cause a white smoke or steam which appears to be smoke. If the engine is at idle that would be the only time you could see that type of hole until it gets bigger. Check for any loss of water/antifreeze in the vehicle.
The engine is pooped.
Because there is antifreeze int he system and it takes a while to burn through. Also replace the bottom hose too. <> If it smokes from under the hood, It has antifreeze on the engine exterior, You can wash it off. Or just drive it and it will burn off. If it smokes from the exhaust, There is engine damage.
You have a blown head gasket.
Means the person smokes marijuana (weed)
Have you spilt some on the radiator?
That would require fixing / replaceing the VALVE SEALS in the heads.
It depends on the kind you smoke, on the person that smokes it, and how. Meaning it varies..
the valve stem seals are probably dried up and leaking when engine is at rest
