My oil pressure is running a little to high like at about 50-60 pounds witch I know its suppose to run 20 at idle and 40 over 1200 rpms ...
Today I got it good and warm an the pressure was running perfect could having to much oil pressure be pushing oil in thru the rings because there only suppose to have 40 pounds to hold back not 60

Incidentally, the usual cause of high oil pressure readings in these things is a failing oil pressure sender.

It's obviously not the Jeep that's blowing smoke.
Notice he cannot follow instructions, won't answer questions, won't do as told, and comes up with new ailments all the time.
Finding out WHY it smokes is so easy! --- IF it really did!
