Cold start up problems and engine runs bad and smokes white smoke
2006 F-250 Power Stroke 6.0 problems. When the engine cold ( the colder the worse ) it takes three or four trys to get the engine to run. Once it starts I must let it idle to warm up to temp or I will expieriece lack of power thus no shift in trans and excessive white smoke from exhaust until the engine reaches temp. I changed the EGR valve which had a lite build-up of soot and that did not solve the problem. I have maintained the engine,freq oil and filter changes,do no heavy hauling and the engine has 128,000 miles on it. Any suggestions?
Re: cold start up problems and engine runs bad and smokes...
How cold oustide is it when this occurs. Sound to me like a stiction issue. This occurs when the oil is thick when cold the injectors coils cannot open and close quick enough thus not being able to inject. Glow plug issues are fairly rare on the 6.0. Also the FICM may be at fault turn your key on listen for the injectors if they do not cycle i could almost guarantee the ficm is failed.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

White smoke indicates water going through your engine or condensation in your exhaust. If it is a lot of smoke you probably have a small leak in your head gasket that seals back up as the engine warms and the materials expand. It will get worse as time goes on. If it's just a little smoke that doesn't last long it's probably condensation in your exhaust, especially if it's cold outside. Condensation is caused by the air cooling down in your exhaust after you shut down the engine.
The thick white smoke is either burnt oil or steam you can easily identify the smell of burnt oil not really sure why you thought it would be a good idea to put a 2 stroke mixed fuel in but more than likely that alone fouled your spark plugs. But if the problem preceded the fuel blunder then your either have a bad intake/head gasket, leaking valve seats, or bad main engine seal. Replace the spark plugs and check cylinder compression. Change your engine oil and check to see if it contains water/coolant also watch for coolant or oil consumption
If I had to speculate I would say you have a weak oil ring ! Especially if you are blowing bluish white smoke. The oil is really slow getting to that certain lifter. that's why you hear that tapping. It may be worse on colder days. (Oil being cold)! Eventually you will have to fix this problem.
you don`t say what color the smoke is so this is a basic indicator with different colored smoke.if it is white smoke like you would see from any car started up on a cold day then this is normal for cars as the exhaust is hotter than the ambient air temperature.if it is a thick heavy looking white smoke and has a sweet odour then this can indicate a coolant leak into the combustion chamber after sitting overnight such as a bad head gasket,if it is a blue smoke then this indicates oil leaking into the cylinders past the valve seal or valve guides on a cylinder that is on the intake stroke when the motor was shut off,if it was rings it would show only under acceleration,if it is black smoke this indicates an overly rich fuel mixture.
If the engine is using oil then first remove the dipstick and run the engine, check to see if heavy smoke is coming out of the tube, this would indicate worn piston rings,if it is not so dense, yet you are using oil and it smokes bad from the exhaust, then its likely the valve seals are worn. either way, unless you have mechanical knowledge, tools etc , you need to take it to a mechanic for the engine repairs or live with the oil consumption. There are no quick fixes for engine wear.
My first thoughts are that you have a head gasket or intake manifold gasket failure. This is why you have the white smoke. If you run it too long, your catalytic converter will be destroyed. Check for coolant in your oil too.
