Oil burning smell and smoke coming from engine compartment near windshield by driver side. The valve cover gasket was found to be the problem; it was leaking on the hot manifold. Had the valve cover casket replaced ($265). Problem fixed.

After driving the car for short distance, oil starts smelling strongly. I haven't noticed any obvious leaks in the garage, just the smell of oil more from the passenger side than the driver side.
