Engine oil capacity is dependent on your specific engine model and can be determined by checking the Oil Recommendation FAQ. Either the crankcase breather has failed or the oil is contaminated. The crankcase breather vents the gases and excess pressure from the crankcase and sends them through the carburetor to be burnt in the combustion process.

Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke. One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder hea a cracked engine block, or head gasket failure caused by overheating.

A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. To be more specific, the white smoke you see is your diesel fuel, unburne or only partially burned. The commonest reasons for this lie in the fuel system.
