White smoke coming out from newly rebuilt manifolds (1 Viewer)

I took my intake/exhaust manifold off and rebuilt them. I painted the exhaust with ceramic paint. I used copper gasket maker on both sides of the gasket.

I just turned the truck on for the first time and after about a minute I’m seeing some white smoke coming out near the down pipe and in some areas of the mating surface. I have some videos here:

Is it a leak? Is it the ceramic paint? The copper gasket maker? Should I worry?

The smoke continues for a bit after I turn it off

It looks like normal grease and other organic material burning off as the manifolds heat up. It if doesn’t stop after everything gets up to temperature after 10 minutes then you can worry about it.

Thanks again @Pin_Head, you were right. Turned it on this morning and the smoke and fumes went away after a few minutes.
