Oil Leak-What have I done?!

Danny, it's quite possible when you went to WOT, it caused a bit of pressure and forced the oil out of who knows where. It could be simply coming out around the valve covers and running down the back of the block.

Mechanical oil gauge? Is it leaking there?

PCV on one side, and a breather on the other will/should help.

On a side note, Bars leak is probably not the best solution.
