I've copied this link which provides info on some of the causes of white smoke. The first thing to check is the coolant level in the radiator. Take the cap off only when the engine is cold to avoid burns.
Is it condensation or actual smoke? White smoke is associated with diesel mixed in petrol and with quite strong smells. I suspect that it is condensation as water vapor is a by product of combustion and the motor/exhaust will have to warm up to clear it. Check for water droplets at the end of the exhaust to confirm condensation. Burning oil will cause a blueish smoke to emit from exhausts.
If smoke is black indicates too much fuel If smoke is white Could be coolant in the exhaust system If smoke is blue possible excessive oil entering in the combustion system Also if you have an automatic transmission with a vacuum modulator, it could be leaking transmission into the combustion If you have too much oil in the engine, it will also smoke
this sounds like you may have a head gasket that is leaking. you will need to have the compression on the engine checked when it is cold to see what is going on.the smoke is from coolant that has leaked into the engine and is being turned into steam and this is what you are seeing and once it warms up the leak seals off and should stop smoking
As you said engine light is on and misfire with white smoke, it clearly symptom of poor ignition spark may cause of any wire got disconnected or spark plug faulty.
white smoke comes only in case no spark at spark plug and un burn fuel throwing from silencer. check wire and spark plug if any issue let me know. thanks.
When an engine expels black smoke it means that the piston rings are going and is consuming oil. And when the color of smoke is white the engine is consuming more fuel. Both are harmful. Black to the engine and pocket while white to the pocket. It seems that the injector need careful attention.
Cold engine does expel white smoke initially. When the temperature rises to normal working temperature the smoke stops. This is normal in your case. 5 to 10 minutes to warm up is normal for any diesel engine. But any thing more than that needs attention.
Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked. Thanks. you can rate this solution and show your
oil drop from the valve stem (from engine head to cyclinders)
diesel soot collect inside the exhaust system.
I will take a 5-10 minutes high rpm (not redline) ran on the highway.
Pay close attention to the rear view mirror and look for black diesel soot.
I will use Diesel Cleen or similar product to condition the fuel. (keep moisture down)
Use the recommended amount of SEAFOAM oil additive to condition the valve stem seal/rubber parts.
I can not rule out excessive blown by.
Can you get a diesel compression tester?
When was the last valve adjustment?
Please post the actual odometer on the engine and I will follow up on it.
