White smoke coming from exhaust

I checked valve cover , pcv , did head gasket test , no milky oil , no bubbling resivoir , engine does not over heat . White smoke only comes out when I rev it not on start up. A lot of condensation at tip of exhaust but doesn’t look like oil or coolant when I touch it and doesn’t smell like any of those either .

Do you see a drop in coolant level after some time of driving?

Maybe have a leaky injector or turbos going bad.

Yeah but I was told I have a small crack in the radiator and that was the reason for my coolant level dropping.

Is there a way to test for those ?
Or would it be an obvious sign when taking them out .
