its got to be something along the lines of pcv valve,the hose that connects it or anything around that area.if you have aftermarket valve covers do they have baffles in them to prevent the oil from getting in the pcv valve?
here is a link from stangnet. http://www.stangnet.com/mustang-foru...e-tube.609340/

Re: Oil in my air intake

If it is in front of where the PCV hooks up and has a K&N or other cotton, oiled style filter, then someone has over oiled it or not let it dry properly.
Clean everything inside especially the MAF sensor.

If it occurs after the PCV connection and is excessive then you may have worn rings and some blowby.
With the engine idling at normal operating temperature remove the oil fill cap and see if it puffs up out of the valve cover. If it does then blowby is the problem.
