Today I was driving my 94 HARD on the highway for about 2 miles, I got off and pulled into my driveway. Just for the sake of the car I figured I'd check the oil level and such, when I popped the hood some smoke was coming out of the drivers side of the engine bay, I couldn't really tell where it was from but it smoked for 2-4 minutes. This is white smoke and kinda smelled like oil but not really, what else could this be? I have checked the enginge bay like 5 times since this and all times I see no smoke, just that once. Any thoughts?? BTW: The oil was a little low and I didn't have the time to check other fluids.

Thanks in advance!
