Oil was leaking cloud of smoke and burning smell, had the gasket and engine cover changed, now I have an engine check light, so I'll find out what that is, but I did add oil and it went away, 3 days later it came back so I'm not sure, but no performance problems what so ever.

I bought the car knowing about the slight oil leak from the valve cover gasket. It's small but the smell is starting to annoy me.
I believe that the oil is leaking from the rear of the valve cover. Oil is dripping on the exhaust and smoking. A drop at a time about every minute.
