1993 Chevy Cavalier Head Gasket or Hose?

My car is not smoking under the hood, it seems to be under the vehicle itself. It doesn't appear to be coming out of the tailpipe. I did watch the car as it was running. The smoke is white. It is not smoking into the cabin. I wasn't able to let the vehicle sit for long enough earlier to see where the antifreeze was dripping because I was concerned with getting the vehicle home, although now that it's been sitting for a while so I might be able to at least figure out where it is coming from. I did stop often to at least put water into the reservoir so that it would not become dry. It appears to be coming from the back of the engine block. I suspect maybe that the antifreeze is hitting the exhaust and that is why it's smoking. The weird thing is that there will be some spurts where it would stop smoking for a few moments, as if everything was normal and then start doing the same thing over again. My dad seems to think maybe it might be a heater hose, since the vehicle was leaking a small portion of coolant before, but was unable to track down where the leak was coming from, and there was no blowby. The intake had been replaced before I had gotten the vehicle back in January and I had just had the ignition control Module replaced (not sure this would matter much, just thought I'd mention it)
