Puff of smoke at start-up

[Blackgoat]

Hello everyone
Yesterday my wife backed out the 4 runner and I noticed a pretty substantial puff of white smoke.
After running for a minute it went away but it is still concerning.
I have 44k on he clock .
Should I have the dealership take a ook or dont worry about it?

It's more than likely condensation burning off.

If it has a sweet smell, it could be coolant burning due to a bad head gasket or head.
But if that were true you might notice it running a little rough as well.

So probably just condensation.

I went ahead and took it to the dealership yesterday. They say if anything it could be a bad valve or Head gasket issue.
I will update .

At 44k the most likely explanation is water condensate. KISS, Occam’s Razor.

Keep an eye on coolant and oil levels for the next few thousand miles.
