your cooling system is preasureising due to a leaking cylinder head gasket the white smoke you see is coolant passing through the exhaust valve on the offending cylinder have the cooling system tested for CO content hope this advice helps

I have an old IDI 6.9 diesel. They tend to burn oil, and that would be normal. Just keep a check on your fluids, and unless the smoke is excessive it should not be a problem. I must say though, I personally think the IDI's were the best diesels ever built. They last forever. If you really want to treat your truck to a nice treat, after you fill your tank, dump a quart of auto trans fluid in the fuel. The additives, cleaners,and lubricants in the trans fluid really help to clean all the carbon and build up out of the injection pump, and clean the gunk from the valves and cyllinders. I usually do it every other month or so.

White smoke from the exhaust is a sign of coolant entering the combustion chamber. You say no coolant loss, or overheating. Is there a white foamy substance under the oil cap, & air bubbles escaping from the radiator? If so you have a leak and more than likely it is a blown head gasket. I would have a cooling system pressure test run. Do not continue to drive this Ford in this condition. Something is not right and you need to find out what is going on.

White smoke means that you have a coolant leak. Two possible causes for that - either the head gasket is punctured and must be replaced or the head itself is damaged and must be welded by an expert.
Either way the engine must be dismantled to make a full diagnose and repair.
