What does it mean when smoke is coming out of you engine oil cap and dipstick?

While driving on the freeway I was doing about 100 I heard a loud pop sound come from my engine and all of a sudden I lost power and my car drifted to the side. I opened up my hood and smoke was coming from the back of the engine and out of the oil dipstick. When I pulled the oil dipstick out I noticed that it was bent at the point where you would say your engine oil is full. Smoke was also coming out of the engine oil cap. When I went to go crank it over after waiting a bit it wanted to start but it just wouldn't catch. Could it be that I cracked, broke, or bent my crankshaft which caused my oil dipstick to be bent.

Do you
have the same problem?

A cople of things can cause this. A blown head gasket which is filling your crank with pressure it's not supposed to have or as you r dipstick was bent, i'd say you broke a piston or rod is a more likely cause.

Was this
