Question about Toyota Cars & Trucks
Have you done anything to the engine ( rebuild with new rings etc). The oil has to go somewhere and the only place is out the exhaust as blue smoke.place the vehicle on a hoist and check under the floor pan area for signs of oil on the metal under the car as there may be an oil leak that is squirting out into the air stream under the car.

SOURCE: white smoke from exhaust
Good check you have done.
Good for you head gasket is still good.
Bad stem valves can let the oil leak in to the combustion chambers causing smokes. Since the engine is Shaky on acceleeration, you need to check the compression presure to see if valves not seating properly ( poor compression ) besides the stem valves. Good luck.

The likely cause is coolant leaking into the cylinders due to a failed head gasket. You should be losing some coolant and need to top it up so check the level. You will also find that coolant is finding its way into the lubrication system and "contaminating" the oil.
Remove the dip stick to check the oil and if you can see a whitish substance in the oil you have coolant in the lubrication system which is is leaking through the failed head gasket.
You may also see traces of oil in the vehicles cooling system so look there also.
The only fix for this problem, once properly diagnosed, is to have the head removed from the engine and a new head gasket fitted. The head would also need to be checked carefully in case of cracking and in any event would most likely need to be machined by a head specialist before being refitted.
The `cause of the failure is unknown but if the vehicle has ever been operated with an overheated engine (due to problems with the cooling system) this is enough to blow the head gasket and to potentially damage the head on the engine.
Not good news I'm afraid so please get it checked out and properly diagnosed with a reputable auto repair business.

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.
