Finally got her back up and running after the HG job. Let her run for a bit to warm up, but she started smoking a lot after a few minutes, so I cut it.

White smoke coming from the back of the exhaust, and tons of smoke coming from under the exhaust manifolds and around the cats. Is this just residual coolant burning off/out? It smells more like burning plastic, rather than anything sweet. I don't see anything rubbing any belts or moving parts.
