I have a 94 oldsmobile cutlass supreme with 180000+ mileage. The engine is a v6 3.1liter. I have a lot of white smoke coming from my exhaust when I give it some gas. The engine knocks a little and it sounds different when I start the car. When I first noticed the problem I saw what appeared to be steam coming from the back of my engine under the hood. What could possibly be wrong. I suspected it to be a blown head gasket, but my cylinder block may also be cracked. What do you think is the problem? Please help me.

The coolant isn't low and there doesnt appear to be any oil mixed with it or water in the oil. What do you think it could be

if it knocks a little, you could also have a piston problem.
a compression test could show somwthing.

The exhaust smells like the engine is burning rich and the oil kinda smells like gas
