That's bad news, and probably the source of your problem. It could be worn valve guides, intake gasket sealing alignment, or worn cylinder walls and piston rings. A leak down test is a good place to start for what is causing this.
Oh yeah, and I'm pretty sure if the PCV (positive crankcase ventilation) valve is inoperative it can cause too much pressure buildup and shoot oil up into your combustion chamber. So maybe the PCV valve is your problem and the #3 cylinder is the only cylinder that is worn down enough to let oil shoot past the piston rings? So start right there. Go change your PCV valve and your spark plugs pronto! Then come back and tell us how it worked.
