SOURCE: 83 Ford F350 Diesel Dually Smoking from oil

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.

SOURCE: white smoke coming out of exhaust, engine not

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.

SOURCE: My isuzu 4JA1 engine tends to exhaust white smoke

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.

Engine block is cracked. So oil and water are mixing with fuel. You need a new block or buy new car

Blueish white smoke comeing from exhaust


Hello There

White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket.
Black smoke is caused by a rich fuel condition.
Blue smoke is caused by oil consumption.

You need to check your oil cap for yellow/white gunk on the cap if you have this then this is a sign your head gasket is cracked. Check to see if your radiator coolant level is down this is also another sign.

Hope this helps. Please don't forget to rate me.

Many Thanks

Why is there loads of white smoke coming out off my exhaust bad an I think oil two ???


the main problem caused by white smoke is either steam which is head gasket leaking water into cylinders /and will also have condensation or water out of the rear end exhaust ,or if running ok and no loss of water in radiator and starts ok then could be a mix of fuel .but if you are loosing water then its the first problem.
As if it was oil burning then its black smoke you should have not white.

When starting vehicle was getting just a *** of blue/white smoke from exhaust after driving a few miles it has turned into a smoke machine billowing sblueish smoke from exhaust this is a not turbo engine.


Blue smoke from the exhaust is cause by coolant\water mixing in the combustion chamber. The smoke will also have a sweet smell to it. A simple way to confirm this is to check your coolant level. Also if you take the radiator cap off while the engine is running you should get exhaust fumes coming out since the mixing will be both ways. Although this is not always the case the coolant can mix with the engine oil as well so check that as well. The oil will have a milky brown color to it.
There are several things that can cause this but the most common is a blown head gasket. It could also include a warped or cracked head as well.

This usually happens after the engine overheated for a prolonged period of time.

You should get this taken care of A.S.A.P.
Hope this helps and good luck.
Please let me know if you need anything else.

Its blowing white smoke from exhaust


Sounds like you blew a headgasket. When this happens water can mix with oil and it makes the oil look white and foamy when you look into the oil fill cap. Another version is oil mixes into the water and gets into your radiator, this makes the same thick white mess and both versions would have to be thoroughly flushed depending on which got into the other. You could of also just blew the gasket between a water or oil jacket and a piston cylinder. This will cause the fluids to pump into your cylinder, heated and then be forced out the exhaust pipe. If water is mixed with this it will billow out white smoke(steam) in huge amounts. I would check your water levels and oil levels very quickly to make sure it does not empty those systems out and burn your motor up.
The last item is the worst outcome. If a crack somehow was created in the engine block or the head of the motor, the same thing could happen as it exited out the exhaust pipe. Though this is the worst case of really thick white smoke out exhaust.
Resolve: time for a mechanic to diagnose this one before it stops running completely.

I have water mixing with oil and they say it is not my head.


Most likely, it is one of the two head gaskets.
Possibly could be a cracked engine block, but not likely.

What are the symptoms?
White smoke coming from the exhaust pipe?
Overheating engine?
Radiator eruptions?
White goop on oil dipstick?
