turbo seal is blown allowing oil into air intake charge-white/blue smoke=oil- black smoke=rich fuel mix-replace turbo-cheers Denny

Does it blows white smoke ? And have you noticed oil in the end of exhaust pipe. If so remove the intake from turbo and check the shaft movement, and rebuilt your turbo. This http://www.turbochargerpros.com/repair/ford-turbo-repair.htm helps to repair your Ford turbo. If it is black smoke, you must replace your Fuel Pressure Regulator.

Yes if the oring did not seal then the coolant seepage or if the timing wasnt advance the youll blow white smoke real big big white smoke

You have to change proper piston and ring.

2001 7.3 TURBO DIESEL ,CRANKS WHITE SMOKE COMING OUT OF THE TURBO, AND THE TAIL PIPE NO START

White smoke (sweet smelling, too) means antifreeze is leaking into the combustion chamber, blowing out the tail end of your truck. the boiling water in your reservoir means the pressure from the combustion chamber is pushing air into your cooling system which will eventually surface in your reservoircontainer

black smoke: it can be unburned fuel damaged turbo charger etc. light amount of smoke can be normal large amounts = problem.

White smoke is a sign of water which may be a sign of a blown head gasket..... havve a reputable shop do a compression test on this vehicle.
If the car runs a few minutes does it overheat??? If so turn it off and dont drive it until it gets fixed if not white could be condensation and low batteries could be just in need of replacement and or a good charge.

My 2004 was doing the same thing and it was the egr cooler, i bypassed the cooler and replaced the oil cooler while i had the top of the engine apart,problem solved

well the question is where did the coolant go. if it didnt leak out it must have went out the pipe. As you stated, white smoke, white smoke is coolant. You definately need to get this to the shop. You cannot drive it this way or further damage will occur.

yes it is most likely the turbo oil seal is leaking.
