fired up the celi today...white smoke *sigh*, have a few questions Options

[Benevolence]

Ok so I started up the celica this morning (sure was cold!) and noticed more than usual amount of exhaust smoke and a slight hesitation when I cranked her up.

I did some reading around and the first think I crossed off the list was that it wasn't condensation from the cold morning since its still doing it now and its around 70 degrees.

So after reading and searching it seems like the coolant could somehow be getting mixed with the oil or I have a blown head gasket, so what I'm wondering is how much (general pricing) to get this thing fixed and an estimated down time to fix it.
