90q exhaust

[Eyvind Spangen]

A friend of mine has got a 90q (10v) which has started smoking a lot
lately. It's cold here now, so I know that moisture in the exhaust
makes some smoke, but this car smokes thick, the exhaust really stinks
and it idles very rough.. The exhaust is white in color. I don't
really know what it smells like. It might smell a bit of coolant, but
these engines are not known for blowing head gaskets?

A radiator hose popped off recently, and he drove about 1 mile after
the low coolant warning lighted up. Could this cause a blown head
gasket?
