Narrative:
Day VMC conditions prevailed I was acting as pilot flying. While climbing through 25;000 ft. The caution cas message 'left-engine oil pressure high' was displayed intermittently at first and then latched. PF (pilot flying) and pm (pilot monitoring) noted elevated engine oil pressure readings and slightly elevated oil temperature. I requested to level at 29;000 ft. And fly present heading. I called for the QRH actions for the associated cas message which were to simply reduce power on affected engine. End of procedure. As power was reduced intermittent 'left-engine oil pressure high' messages remained displayed. No messages were displayed; or abnormal indications were displayed at idle thrust setting.we elected to discontinue the flight and divert to ZZZ. I [advised ATC] as it was unclear in that moment if a precautionary shut down would be required. We elected to leave the engine running at idle as an extra source of power; bleed air; and hydraulics. We landed at ZZZ in degraded condition; left engine at idle; without incident. Oil was found on the bottom of the cowling during the post flight.passenger accommodations were made; and we recovered the trip with another aircraft.
