I put 10W30 in rather then 5W30. Because when I speed up the car black smoke coming out of muffer. When engine is cold White smoke coming out of engine too much. Engine oil is not milky at all but every month I check the oil inlet thers is white cunk. Is this indicate water jacker has a hair crack or to do with coolant vapor in.
Based on the smoke I would say you need to rebuild the engine.
Could be a leaking head gasket, or other problem.
The milky oil in the filler pipe means there is an excessive amount of moisture or water/coolant in the crankcase.
SOURCE: engine oil mixed in coolant
this would more than likely be cause by a bad cylinder head gasket. I would bet 89% this is your problem.
SOURCE: White smoke exhaust
White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....

It could be the intake gaskets or even still the head gasket. How about the coolant ? Did you refill with same type coolant ? Have you noticed if it's thick and gooey ? mixing coolants will sometimes produce a thick gooey coolant that clogs up the cooling system. If the car ran hot it could also be a cracked head or block. Warped heads also. Somehow the coolant seems to be getting into the cylinder(s).

It sounds like you're either low on coolant or have a stuck thermostat. If you're low on coolant you may have a leak. For coolant I recommend using 50/50 mixture of antifreeze and water. You can buy pre-mixed 50/50 antifreeze or buy the 100% and dilute it with 50% water. The thermostat is a temperature controlled valve. It's held close by a spring until the desired engine temperature is reached. It then opens and allows coolant to flow in a loop from the radiator to the engine. If you're low on coolant or the thermostat gets stuck the engine will overheat which will cause the temperature gauge to rise. As the temperature increases so does the pressure. When the pressure and temperature get too great, very hot coolant, approaching steam temperatures, will find some way to escape and show up as smoke from your engine. Do not try to add coolant when the engine is extremely hot. Wait for it to cool. Be very careful removing the radiator cap when the engine is hot. Hot gas and liquid can come spurting out and burn you badly. You can add coolant to the overflow reservoir safely since you don't have to remove the radiator cap to do this. When your engine is hot try to find where the coolant is leaking from. It may be something easy to fix like replacing a radiator or heater hose.
SOURCE: heap of white smoke on startup but not always
White smoke usually occurs when there is not enough heat to burn the
fuel. The unburned fuel particles go out the tailpipe and typically
produce a rich fuel smell. It's not unusual to see white smoke in the
exhaust during cold weather until the engine warms up.
Faulty glow plugs or control module can cause white smoke on engine start up.
Low engine cranking speed may also produce white smoke.
If
white smoke is still visible after the engine has warmed up, the engine
may have one or more bad injectors, retarded injection timing or a worn
injection pump.
Low compression or air in the fuel system can also be a source of white smoke.
