Re: Blown head gasket?
Did you change the oil? If the car has been sitting for a long period of time, its possible that condensation has accumulated in the oil. What you may be seeing is it's finally burning off. If you don't let engines get to temp, this is a common problem.
You may have a blown head gasket too, but I would change the oil and take a look at the old stuff and check to see if it looks milky.
