I was in cruise flight at FL220 when I noticed the right engine oil pressure fall below green. I contacted ZZZ to return to home base, advised them of reason. After turning around oil pressure continued to drop. I elected to shut down that engine, utilized single engine procedures, and returned to base. I was cleared to land. Upon lowering the landing gear I did not receive a three green light indication, signaling that my landing gear was not locked in place. I did a 'fly-by' with the tower to confirm, then executed a manual gear extension, and landed without incident. Callback conversation with reporter revealed the following information: the reporter stated the engine was a lycoming 541 turbo and the cause of the loss of oil pressure and quantity was a seized oil ring which pushed the oil out the breather system. The reporter said the engine incurred no major damage due to being shutdown when the oil pressure and quantity started to drop. The reporter stated an emergency was declared.

Title: A BEECH 60 IN CRUISE AT FL220 DECLARED AN EMER AND DIVERTED DUE TO R ENG LOSS OF OIL PRESSURE AND QUANTITY. SHUTDOWN R ENG.
Narrative: I WAS IN CRUISE FLT AT FL220 WHEN I NOTICED THE R ENG OIL PRESSURE FALL BELOW GREEN. I CONTACTED ZZZ TO RETURN TO HOME BASE, ADVISED THEM OF REASON. AFTER TURNING AROUND OIL PRESSURE CONTINUED TO DROP. I ELECTED TO SHUT DOWN THAT ENG, UTILIZED SINGLE ENG PROCEDURES, AND RETURNED TO BASE. I WAS CLRED TO LAND. UPON LOWERING THE LNDG GEAR I DID NOT RECEIVE A THREE GREEN LIGHT INDICATION, SIGNALING THAT MY LNDG GEAR WAS NOT LOCKED IN PLACE. I DID A 'FLY-BY' WITH THE TWR TO CONFIRM, THEN EXECUTED A MANUAL GEAR EXTENSION, AND LANDED WITHOUT INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ENG WAS A LYCOMING 541 TURBO AND THE CAUSE OF THE LOSS OF OIL PRESSURE AND QUANTITY WAS A SEIZED OIL RING WHICH PUSHED THE OIL OUT THE BREATHER SYSTEM. THE RPTR SAID THE ENG INCURRED NO MAJOR DAMAGE DUE TO BEING SHUTDOWN WHEN THE OIL PRESSURE AND QUANTITY STARTED TO DROP. THE RPTR STATED AN EMER WAS DECLARED.
