Too high an oil pressure can wash out bearings.
By too high...I mean very high....in the 100+ area.
Oil flow is more important....a good high VOLUME oil pump is normally called for in very long life engines.
And...the oil pressure relief valves can be checked for operation (and should be) whenever you change the oil (if only by checking the higher pressure relief by reving the engine when it is fairly cold).
The pressure should rise quickly then stay at one point reguardless of revs (higher)...this shows the high press relief is working.
Oil is the lifeblood of the engine....keep it cooled...keep it clean.
