Blown Head Gasket, or Cold Weather?

[u/Alligatorgamer9]

This is just after 2 bottles of K-Seal. The exhaust used to smell sweet, but now it’s almost odorless. It’s currently 2am and 39*F. The smoke also easily changes direction in the wind and alternates between rising quickly and staying low to the ground. The thickness of the cloud is also variable.

Is my head gasket screwed or is it just the cold weather?

once you smell ethylene glycol on hot exhaust, you will never forget that sweet smell of dying motor. if you do not smell something sweet, it is not that.
