If oil on top of the valve cover likely you have either over-tightened the VC mounting bolts causing a crack in the cover or the oil cap gasket is bad.

Oil in the plug wells indicates that the valve cover plug gaskets are not sealing (pinched or misaligned). Likely would need to be replaced.

Do the easiest first. Replace the oil cap, or just the seal for it, if that doesn't stop the leak, then move onto the valve cover gaskets.

Yep, either the valve cover was over-tightened and cracked and/or the oil cap gasket is bad.

one thing you want to do is double up the oil cap gasket as soon as you can. Go to the Mitsubishi dealership and ask for this part #: MD311638...........leave the original gasket on there and just add the new one on top of it. This will eliminate any leakage from the oil cap.

Good luck trying to get the cap off when the motor is warm...I did this and it is so tight that you really need to grab and twist with your whole arm. I guess the double gaskets expand when it heats up? Anyway, just a warning. The cap doesn't leak anymore though .

A puddle of oil is a lot of oil coming from a worn out oil cap gasket unless this happened over a long period of time. If all of this happened within a short period of time which I suspect, you might want to investigate further and find out why your crank case is being over pressurized. Are there any other signs like popping your dipstick or smoking exhaust. It may turned out to be just the gasket but it wouldn't hurt to double check before it's too late especially now you have just sealed off one of the few outlets left.
