From the pics, is it the front cover that is leaking? Before I thought my oil pan leaked, but its coming from above the oil pan. Its coming from the area of the red arrow and it flows below the crank angle sensors and straight down. I see it leaking on cold startups, but once my engine is warm, it seems to stop.

 

looks like the front cover leaking i just replaced mine 6 months ago mine had the crappy paper gasket in it put the metal one in

 

there is more load on the engine at cold start up ...so it probably leaking while you are driving as well...clean up the oil good with some simple green and start the car again you should see where its coming from

might be front main seal
bad front cover gasket
cracked housing
