Question about 2002 Jeep Wrangler
My jeep overheated on my way home, pulled over, and the radiator is cracked. Filled it up and headed out. Temperature was then fine on the ride home; however, the oil pressure kept pushing 80. I had to put the car in neutral in order for it drop. I am replacing the radiator; however, I would like to know why the oil pressure was running high?
One possibility is that water has mixed with the oil forming a thick chocolate milk like mix that when pumped through the system increases the pressure

if you know for certain that the sending unit is correct and the guage is accurate, then yiu may have big problems.....while the engine is running open the oil filler hole.. is everything wet with oil? or does it look dry or just a little lubed? you can allways install an aftermarket oil pressure guage(crappy tire) if you get the same results with that then you may have a week oil pump....worst case scenerio... need an engine rebuild as the moter may have wear issues.does the pressure slowly drop as the motor warms up? at idle ? does it jump up when you step on the gas?

u Have a problem with the oil sending unit. The sensor is located beack right side of the engine block. Take out the switch and make sure u have good oil PSI. Should be 6 psi at idle and around 50 at 4000 RPM. If the presure is ok replace the switch they are very cheap about 20 bucks. Please rate.

SOURCE: Cracked Cylinder Head
I'd say moderately difficult: here are the instructions for replacing the head on a 2001 Jeep Cherokee Sport with 4.0 L engine:
REMOVAL & INSTALLATION 4.0L Engines
Cylinder head bolts may only be reused one time. If reusing a cylinder head bolt, place a paint mark on the bolt after installation. If a cylinder head bolt has a paint mark, discard it and use a new bolt. NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
During the final tightening sequence, bolt No. 11 will be tightened to a lower torque value than the rest of the bolts. Do not overtighten bolt No. 11.
