Default 93 PA is rough and white smokey

93 Park Ave with 135,000 on it. v6 3800. Been using some radiator fluid and now its running real rough and blows lots of white out the pipe. also some white smoke from windshield side of engine. Have had some brown gunk on radiator cap too.

Thoughts? Links?

How is the oil condition? What engine is it? Naturally aspirated or supercharged?

There are only 2 places that the engine can ingest coolant. The Upper intake manifold/Supercharger and headgasket. The latter is pretty much unheard of, the former is most likely. If the oil looks like a milkshake, the Lower intake manifold gasket is the likely suspect. Both failures are rare. You can also check the throttle body gasket. If it fails, coolant goes straight in to the intake. I would check this first in all honesty.

No supercharger. Oil seems ok. How would I check the throttle body gasket?
