Smoke from exhaust after hard acceleration

[leosuarez]

I have an issue where white smoke will come out of the exhaust only for a few minutes after a hard acceleration. Coolant levels seem to have stayed the same, anyone know what could cause it?

It COULD be moisture from the mufflers if the car has been, or does sit for extended periods.

I drive it every day and it parks in the garage

How's your oil consumption between changes?

Not too bad I don’t notice a dramatic amount to be missing

First question would be what is the color of the smoke?
Blue
White
Black ?

White

Then it’s coolant
Condensation only happen on a cold engine/exhaust system

Are you sure it’s white? I only ask because I’ve seen people misinterpret the colors almost always.

2018. How long have you owned this car?

What is the mileage?

Does the car have any mods installed? Please list anything non-factory.

Is the car tuned?

Are you using pump gas? E85?

How long ago did this problem first show itself?

What is the average coolant temp when driving? Does it seem stable?

Are you adding oil between oil changes? How often are you doing oil changes?

"Not too bad I don’t notice a dramatic amount to be missing [engine oil]" Can you quantify that?

Looking at the oil level now, what does the oil look like? Oil? Or is it milky/cloudy?

- Check the inside of your tailpipes. See if they seem oily/sooty, are dry or have residue

- "Coolant levels seem to have stayed the same". Continue to monitor, with photos or notes. Check the same way (cold, before start, or, just after shutdown), each time

- At the next oil change, take a sample and send in for oil analysis. If things are OK, the results will quantify that. If the results show anything of concern, it'll could help identify problem areas, how bad things are, while establishing a baseline. The answer won't necessarily be an "ah-ha!" moment. Analysis is one tool which can help in determining if a problem exists

Without knowing anything else about the car or the situation...

That the appearance of the smoke occurs only for a few minutes after a hard run and then stops implies oil. Excessive crankcase pressure (piston ring blow-by), oil being pushed up and captured by the PCV system, a poor PCV system, improper venting, etc.

With coolant-related issues, some problems can seal themselves once the engine comes up to temperature. Other issues reveal themselves once the engine is fully warmed and under pressure. But you don't seem to be losing coolant. And after what reads more than one event, it does not appear to be getting worse or happening at other times.

Get up to high speed and take your foot off the gas. Keep down shifting all the way down to like 10 mph then hit the gas and see if it spits out smoke

Are you able to smell the smoke? Coolant and oil have distinctive odors. Are you sure it's coming from the exhaust and not, say, from something dripping on something hot and just blowing out the back?
