I had arrived at FL210 and set the power for cruise flight (31' of MP and 1800 RPMs). Following that; I set the mixture controls. At some point in time after that; I sensed something was not right. The sense was something with an engine. I did not hear banging nor did I feel vibration. But; I quickly checked to make sure the throttles did not exceed 32.5' of manifold pressure and that the prop RPMs did not exceed 1800 RPMs (that was confirmed). A quick check of the engine gauges was normal; but as I was scanning to look out at the right engine I saw oil coming out of the top vent. I immediately shut down the right engine (right throttle - close; right mixture - idle cut-off; and right prop - feather) and continued with the remaining items and appropriate checklists. [I] called Center regarding the right engine and continued to fly the airplane and go through the appropriate checklists. I diverted from my original destination airport and landed without incident.
C421 pilot reported the right engine was shut down in cruise at FL210 due to oil loss and a diversion was completed without incident.
