Is it oil smoke or steam?
Are you getting oil pressure?
Is your coolant temperature rising, and are you losing coolant?
Are you losing oil, and is your oil filter on tight enough to seal?
Is there water in the oil?
Is there oil in the water?
I would give the engine a thorough looking over. Give your best examination to see if fluid is leaking anywhere at all. Check all your radiator hoses for leaks, especially hard to reach ones that feed the heater core. You may have one with a small leak that's spraying hot coolant onto the engine.
If your water pump is bad, it will "weep" coolant. That also could possibly be the steam you're seeing.
If you're losing oil, antifreeze, or both, and can't find a specific place it's leaking from, you may be right in your guess. You could have a serious leak in a head gasket, a cracked head, or a cracked block.
I suggest trying a block, head, and gasket sealer treatment if you're not wanting to take it to a garage. I'd go for Bar's Liquid Copper Block Sealer.
