Hey y'all. Just wondering if this is normal oil pressure reading at idle while engines hot. I haven't been having any engine problems at all and pressure rises as I accelerate, but just want to make sure that I don't have a problem lurking waiting to sneak up on me. Thanks in advance.. Jay

 

Many variable that affect oil pressure so if your looking for a fixed number I cannot give one. Bottom line is you have pressure so don't let that gauge give you gray hair. Years ago most cars did not have an oil pressure gauge and everyone was happy. In 2003 Jeep (and most other manufactures) went to a dummy gauge because they got tired of hearing questions from worried customers. Drive and enjoy your Jeep!

 

Looks normal to me.

 

About the same as my 99 4.0 shows.

 

I think a general rule of thumb is 10 PSI per 1000 RPM. Not sure where I heard it tough. Mine is about that when warm and idling. Usually about 45 when driving.

 

Thanks guys. I figured it wasn't any concern. Just had to ask as I'm planning a camping trip in a couple months up in the white mountains, which is about 4.5 hours north of me and they're some steep mountains to climb on the highway and such. I'm doing my best to go through the engine bay with a fine tooth comb making sure she is ready for the journey.

 

You have plenty of pressure. The minimum spec is 13# at hot idle and you have 20.
How's the cooling system and brakes? Mountain driving will give both a workout.

 

Good info to know about oil pressure. Cooling is pretty good usually sits right under 210. I do plan on installing hood vents and put my upgraded injectors in before I leave. As well as a collant flush and new tstat. The brakes do need some loving, still contemplating if I should do the disc swap in the rear before I leave or wait till I get back. But either way it will get some new brakes.

 

What brand of oil filter is on there?

 

Not sure. I think some cheap autozone special

 

Get a wix filter on there.

 

What benefits does the wix provide cruiser?

 

They're high quality filters, not some marginal piece of crap with glued in filter media and junky anti-drainback valves.

 

Simple enough. I'll make sure to pick one up when i do the rear main seal
