Driver side oil would be at the front, a cam seal, crank seal or head gasket. At the rear, the rear cam seal/cap. Then there's the camshaft cap itself if the cams were removed from the head at the time of the work and not sealed properly. Next would be the valve cover gasket or spark plug tube seal, or whomever did the "reseal" didn't do the oil pan properly and it's leaking. The tube seal would allow for oil to pool in the bottom of the spark plug tube more than leak out, but if it gets high enough, it'll run down outside of the valve cover.

I suggest you clean the engine and look for where the oil is coming out. If you still have it on the car, take the air deflector off from underneath before you clean it, because you will want to get it clean on the bottom, and leave it off until you can determine where the leak is.

Yes. Combustion temps reach 1200°F quickly and the exhaust manifold will heat up quickly also. Oil is probably running on to the manifold flange at the head/exhaust ports.
