no. High oil pressure at times isn't a concern. Low pressure is an issue though.
Oil pressure spec for the Jeep 4.0 is as follows
*Not less than 13 psi at HOT idle
*Between 37-75 psi over 1600 rpms
Mine was jumping over 80psi for a while - turned out to be a faulty sending unit / loose wiring connector
