I have a 2006 f250 diesel, and I have alot of white smoke pouring out the tailpipe...

Danielle, Hesitation and white smoke could be a sign that coolant is leaking into engine cylinders and causing plugs to fowl possible head gasket faulty.. Have a good Technician have a look, diagnose and estimate repair.

Could be blow off valve is stuck or incorrectly hooked up, thus too much boost!

Sounds like you may have blown a head gasket. Did you check the coolant level to see if it is low ?

Blown head gasket for sure if its a petrol engine.

If its diesel then its overfuelling.

One of the head gaskets is blown allowing coolant into the combustion chamber causing the white smoke and low coolant. Also allows oil into the coolant and coolant into the oil.

Get it fixed before you ruin the motor. It is expensive to get fixed, but cheaper than a new engine

Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day

head gasket

I don't drive a Ford but I drive an International and white smoke on start up means the engine is too cold to properly burn the fuel. Your black oil or soot is unburnt fuel. You should look at your engine's preheat system for a malfunction.

Is this a small amount of white smoke or a lot of white smoke? If it is a lot of white smoke it could be a head gasket problem.

1. Do you have coolant in oil or vice versa?
2. Pull spark plugs and inspect for plugs wet with coolant.
3. Do a compression test and check for a low cylinder.

If you have issues in any of these points you will need to replace the head gaskets.
