Yes too much pressue is a problem, hench the pressure relief valve.
To test the pressure you need a reliable gauge and then need to somehow
fit it in place of the old one. This can probably best be done straight
off the block.
If it is indeed reading correctly you need to get it down. Having oil
pressure that is too high will push the oil right thru the bearings and
not lube your motor. Also, if your presser gets much higher you will
learn about your secret oil relief valve, you oil filter. These are
designed to blow the cover when pressure is too high, (so I've been told.)
