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.
