I refueled at ZZZ1; inspected for leaks; and checked the oil (8qts). Departed and climbed to 16;000 feet without issue. After level off I noted a MP drop and slightly increased throttle. At XA:17 the oil pressure dropped below 40. I picked the drop up approx 10 min later when I lost MP and the cabin started climbing and descending 2;000 feet per min; I noted an oil pressure in the low 40s and dropping. All other indications were normal. At XA30ish I diverted to ZZZ and started a descent when oil pressure dropped to 0. I [advised ATC]and continued for ZZZ. I assumed an engine failure was imminent and carried as much speed and altitude as a could. At XA44 on approximately a 6 mile final I sustained a complete engine failure accompanied by smoke in the cockpit; oil soaked windscreen; an oil filler door blown open and flames radiating from the engine compartment. Landing was successfully completed on Runway XXL ZZZ and the aircraft cleared the runway onto Taxiway XX.
Pilot reported oil and engine problems resulting in a divert and landing with smoke; and oil all over the place.
