Narrative:
Departed ZZZ at XA59 am. Departed VFR and picked up IFR clearance climbing through 6500 ft MSL. Climbing through 10000 ft MSL the right manifold pressure slowly started to fall. Through 12000 ft MSL the oil pressure descended out of the green arc. Leveling off at 14000 ft the right manifold pressure and the right oil pressure continued to slowly fall. While investigating the other gauges; I found that the right engine was leaking substantial amounts of oil through the vents on top of the engine. At this point I decide to divert back to ZZZ. Informed ATC that I was diverting back due to engine difficulties. Descending through 12000 ft decided to shut down the right engine and feather. I informed ATC at this time that I was single engine. I landed without incident deemed it unnecessary to declare an emergency. There was no trace of any fire by any means.
