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.

Oil smell inside car, was result of oil gasket leak due to two broken bolts. Mechanic indicated that this is a common problem and there is a service bulletin that adjusts the torque specs when installing new bolts. Cost was $800.
