In reply to Sean. Mine is the same as KG minis injector and misfire. Just had the oil changed, no low levels and no overheating. Only has white exhaust smoke at startup for a minute then goes away for the rest of the day. It only happens at the first startup of the day. I’m at a loss, have no idea…

In reply to Andrew. It sounds like you could be burning coolant. If your coolant level is dropping at all (in the radiator or overflow tank) I would go back and check your work on the heads. Perhaps the head gasket wasn't installed correctly, or maybe the heads are warped. I would measure the heads to make sure they are flat, and probably the same with the block just to check.

Thanks for the great posts and insightful comments. I have an ‘04 fx35 Infiniti. Recently changed the top gasket and cylinder heads after an overheating problem. Once repairs were completed, engine oil got topped up and immediately started billowing out white smoke. Did a complete oil change and the smoke persists. When engine is cold, smoke is absent but starts as soon as engine gets warm. Usually ceases after car has been fired during a drive. Starts coming out again if car is slowed down and resumes acceleration. So once the engine is warmed up, the white smoke pours out even when the car is stationary and just idling. Please is the engine worn out? Or could there be a leak from the valve seal? Thanks!

In reply to lily. If you're worried you can do an inspection. A little white smoke on cold start is often not a big deal if the car is otherwise running fine.

Thank you for the article. My Kia Rondo 2008, after a long drive, the next start will have white smoke coming out of the exhaust pipe. After a few minutes, the white smoke goes away. If keep driving a short distance in my town, it’s just normal, no smoke. But after another 40 min high way drive, the next start will have smoke again. No checking light on, no overheating, no fluid level goes low, no engine roughness. Any thoughts on this? Should I spend $165 to have a repair shop do an inspection? Thanks in advance!

In reply to Steve. Does the car still smoke after it's warmed up?

Kia grand carnival
Lots of white smoke when I start the car after it’s had a drive and been sitting for a few hrs.
I’ve had it at a few mechanic and they can’t find out why
No losing any fluids
Doesn’t over heat
Smoke doesn’t smell sweet but it does have an odour to it.
Runs beautifully but the white smoke if anyone can help be great as 3 different mechanic have no idea.

In reply to Bugus. I don't know. Changing oil shouldn't do that. Was it cold? Are you sure you loosened the correct drain plug, and poured the oil in the right place?

I changed my engine oil and the car started giving white smoke from the exhaust pipe. What could be the cause
