I see white smoke (and gas smell) at start-up in the mornings, and then later it goes away.

Hello,

There are a number of reasons why there will be white smoke out of the tailpipe.
It could be due to a blown head gasket, cracked cylinder head, intake manifold gasket leak, throttle body gasket failure etc.

Are you experiencing any other issues besides the white smoke at startup? Does it do it every cold start? Is it more when the weather is more humid?

Here are a couple of helpful guides:

Let me know of any questions.

Thank you.
