Oil leaking down the exhaust
White smoke is an indication of a bad head gasket and engine coolant getting into a cylinder.
Check:
- dipstick for coolant mixed with oil
- Radiator for coolant level.
If coolant on oil or coolant level low, time for some time consuming and costly repairs.
The fact that white smoke is coming out of your engine could mean that water is being released from a place that it normally shouldn't go out of. Last month my truck was doing that and I took it in for auto repair. Thankfully, though, the issue wasn't as bad as I thought it would be and all they had to do was fix a few holes that were allowing the water to leak. Have you checked all of the areas of your car that hold liquid such as oil, gas, coolant, and water? Efficient Automotive Services Repairs

Hi,
For some reason the Live Session froze. Our apologies for any inconvenience. Please find below the last part of my posts in case you were not able to view them.

what about the piston rings
Benimur says:
that could be checked with a compression tester at your dealer
Benimur says:
so for the moment course of action would include: compression test
dye to determine where the oil went, if no trace found then it could be assumed was burned; change the catalyctic converter, it went as a direct result of oil in the exhaust system
Benimur says:
some remedial/temporary workaround includes installation of an aftermarket oil cooler with its own fan; maintain a lower engine temperature by removing the thermostat (not applicable to cold regions) and wiring the radiator fan to continously work.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings

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

Check the oil fill cap and the radiator cap, see if you have a milky scum accumulation on either one, can indicate a blown head gasket or a cracked cylinder where the oil is burning and allowing water intothe hot cylinder which causes white smoke to be emmitted from tailpipe.
