LQ1 MAP sensor oily

I just recently bought a brand new MAP sensor and cleaned the oil build up inside. Just today about 2 weeks later, I looked at it and there's a whole bunch of oil in there again. What could be causing this?

only thing at would get oily junk in the intake where the MAP sensor is, would the be the PCV. check that for oily goop. nothing else on the intake plenum would have oil in it. May want to install a catch can. chances are your intake is caked in that stuff to. when i did my intake swap, i soaked the hell out of my plennum with brake cleaner and cleaned as much of the gunk out as i could

I had bad problems with oil being sucked into the intake through the PCV as well. New PCV valve didn't change anything. I'm not really sure why it does that. I bought a air/water separator for less than $10 bucks at Home Depot, removed the filter and am using it as a catch can.

Thats wicked nasty. also all the vacuum hook ups are over there i believe thats whats drawing all the oil to it.
