Oil pump replacement on v9x

[Deon]

Hi all. Need some advise please. Redoing valves on 3.0 v6 v9x engine. Engine has done 290 000 kms. Mechanice says I should replace oil pump as precautionery measure while engine is open. No physical signs of damage or extreme wear visible on pump. Pump only from agents and not servisible, so not cheap. Should i replace as precaution or is the mechanic being over-cautious?

At 290,000 ks, with the oil pump being one of the most vital parts, i would be replacing it with genuine nissan
