My guess is now you have an exhaust leak. The *white smoke* you see would normally be contained and directed out the rear where you would think nothing of it, right? Cold morning - steam out the exhaust till it warms up?

They were actually unbolting the Cats????? New bolts on them? Mine are so rusted no socket will fit because the nuts don't resemble nuts anymore. Cutting torch is the only way they're gonna come off.

The hot/cold issue shouldn't be related to the exhaust. Did them thieving bastids do else that you've missed?

Probably a coincidence. Sounds like a sticky thermostat.

Others may have a different opinion

+1 for the exhaust leak in the engine bay.
