Oil pressure running high?

On start up, pressure gauge climbs to 3/4 of gauge. While driving, it goes to the max gauge reading. After a while it drops off the high end. Oil is at the proper levels. Oil / filter has been changed every 3,500 miles. Where do I begin?

My oil pressure is always high. Whenever I drive in idle the oil pressure is normal but whenever I step on the gas the oil pressure goes high. I was wondering if anything is wrong.

Check your fuel pressure switch, it may be faulty and giving your computer incorrect data.

The other possible problem is that the oil pressure relief valve has clogged and is making the pressure go higher, but I think you would have had some more signficant problems if this was the case.

I have a 2000 Grand Cherokee Laredo 6-cyl 4wd with 89000 miles on it. The oil pressure has been 40 - 60 for the life of the vehicle, and all of a sudden it runs at higher pressure. It idles 40 - 50, and goes as high as 75 at higher speeds. I have recently had to replace the head gasket, but still have this issue.

44.00 at Napa.

20 minutes to get the stupid red pin plastic piece out securing the wiring to the unit. (It pulls from the bottom).

2 minutes to remove and replace.

Problem solved.

my jeep's oil pressure gauge will increase in pressure as I accelerate and decrease when I let off the gas petal. What is wrong

Nothing, your oil pump is driven by the speed of the engine, as long as you are not completely losing pressure and are not lining out the pressure on the other end you are fine.

For example, my Audi S4 runs all the way to 5 bar, or 73 psi, when I floor the throttle, though it idles around 1.5 bar, or 22 psi. As a rule of thumb all you need is about 10 psi of pressure for every 1,000 rpm.

I have a 1999 Jeep Cherokee Limited with the 4.0 Strait Six and everytime I start my car the engine oil Pressure shoots strait to 80, when I first bought the car it never did that until I changed the oil, I checked the amount I put in the engine and it was right bellow the safe line on the oil dip stick, im wondering what some it could be caused by? Ive been told it could be an oil pressure sending unit or a plugged oil pump, id just like to know if I should stop driving the car or not because I wouldnt want any more damage to be caused to the engine because I cant afford to fix it right now, thanks for reading and hopefully I can get this cleared up sometime when I find out whats wrong with the oil pressure.

I have a 2002 Jeep Grand Cherokee with 96,000 miles on it. About 2 weeks ago, I began smelling a faint oil smell every now and then. Today, I noticed that my oil pressure gauge is maxed out when I am driving. It fluctuates slightly when the engine is idling. The temperature guage is reading around the 200-210 range. I checked the oil and it looks fine; good color and proper level. The Jeep is about 1000 miles from it's next oil change. I haven't seen any puddles on the floor of my garage. I purchased the Jeep in November and this is my first one so I am not aware of any quirks that they may have. My dealer's warranty just ran out 1000 miles ago, so I am on my own. Thanks for any help that you could provide!

I was driving the other night and the oil pressure jumped from 40 to 80 when I stepped on the gas but would drop back to 40 when I let off of the gas. The next morning heading in to work it pegged out at 80 and wouldn't come down. I changed the oil pressure sensor on the engine block and it dropped back to around 60 and is staying pretty consistent. I also changed the oil and filter. Is it normal or ok to run at 60 or should I be worried about it?

I just changed the oil in my jeep cherokee and when I started it up the oil guage went off the scale. I checked to make sure that there was the correct amount of oil put in and filter. There is no burning smell and the engine seems to be running fine. What is this?

Is it possible you knocked the wires off the oil pressure sensor. When you replaced the oil filter.
