Although mercedes recomend using synthetic motor oil im 90% sure that your mechanics mistake (putting to much oil in it) ruined your piston rings thats what the white smoke is all about!! oil is getting into the cylinders!! make him replace them for free since he caused that prblem im sure he has insurance!!

Why is white smoke issuing from exhaust?


White smoke is coolant burning. Check radiator for oil and check oil cap for foam if you have one or both not good.

Kia Sedona oil light white smoke


Are you sure this is not the low oil pressure warning light, bet that it is. The white smoke may be from a blown head gasket, any shop can tell you just by the smell of the smoke, if it smells "sicky Sweet" then it is coolant being burned in the engine and you have big problems.

If you had white smoke then you have a blown head gasket. Even though it hasnt yet mixed with the oil you are still having the white smoke. Is there any water left in the radiator or reservoir?

It's not suprising that the engine stalled after getting hot considering you had run the engine out of oil as indicated by oil pressure light coming on and needing two quarts to refill it. Now that the oil is replaced, you could keep driving, but it would be wise to investigate why it had got so low on oil in the first place. Refer explanation below. You should check the oil level weekly to ensure it is at the correct level and top up if necessary. For that year vehicle, oil and filter changes should be around the 3,000 mile / 5,000 Km mark.
It sounds like the engine could be using excessive oil by either leaking out or being burnt in the cylinders.. If there is a major leak then there will be oil puddles under the engine after sitting for a while. Excessive oil burning in the cylinders is indicated by grey oil smoke from the exhaust when driving. If engine has oil and grime all over the best way to find the leaks is to get the engine pressure cleaned and then observe where the oil leaks are. The most usual places for older vehicles are the sump and valve cover gaskets followed by crankshaft seals. Oil leaks can also come from a loose oil filter or a faulty warning light pressure switch. If exhaust smoke is excessive then it would indicate worn piston rings and / or valve guides and seals.

not sure the gas had much to do with it. sounds like a blown head gasket. what is the colour of the oil. gray often indicates fluids have leaked into it. white smoke out the tailpipe generally indicates a blown head gasket as well.

Valve stem seals can cause this problem, but normally only when first started. Oil in the rocker cover seaps through the oil seals into the cylinders and is burnt up on start up.
Try a "STOP A LEAK" additive and it may reduce the oil consumption and smoke.
I found some on e-bay and it worked on my tired old escort. It even stopped the rattling tappets.

Engine runs wild with white smoke


If its a 4JX engine then its injectors and seals at fault dont run it any more cos it may blow up - like rods through the side !
The diesel is going straight into the engine without being injected and as the fuel lift pump is mechanical it wont stop on the key .
Should be under isuzu warranty though they are doin that repair on 1998 Troopers over here for free .

I had a similar problem with my 2003 325iT w/59K miles last week, right after an oil change. It did it more often when starting the car, and once or twice when accelerating. Then it stopped smoking and hasn't in several days. My mechanic neighbor suggested that it may have been too much oil, that has corrected itself by burning off. I hope he's right. I figure the smoke stopping is either a good thing or a really bad thing. No engine warning lights or anything, so I guess all is well.
