Exhaust smoke

[Tobydavis11]

I have a 2021 Chevy trailboss custom 4.3l v6 and I have white smoke coming from exhaust on start up and acceleration, but my oil is clean and coolant level is not dropping any ideas on what to check?

Do you have a "sweet" smell coming from the exhaust while the smoke is coming out or is there something that looks like chocolate milk under the oil cap? If so its probably got a head gasket going bad.
