I have a 2002 Wrangler 6 cyl, about 97,000. lately I've noticed that my oil pressure guage is indicating 80psi! normally it's been about 45-50. the engine sounds the same and oil level is fine. I'll pull over wait less than a minute fire it back up and the pressure returns to 45-50. any ideas?

Possibly a bad ground for your oil pressure gauge. I would start with the ground or sending unit for your gauge if shutting the vehicle off gets it to operate normally.

I was so ready to say Spun Bearing until you said it returns to normal... I"ll have to go along with the bad Ground Check the wires to the gauge..

Yeah, if the engine is fine and not heating up or operating differently then more than likely your sending unit is going bad. Cheap part and easy and quick to replace.
