Question about 2006 Nissan Xterra

Open Question

My 2006 Xterra oil pressure gauge is showing as High (all the way to the top) when driving but the engine sounds fine and does not appear to be the actual oil pressure. Is this a known issue?

Most likely the oil pressure sensor is bad. Its located in the very rear of engine on top of bell housing area.

Most likely it's the oil sending sensor, located beside the oil filter. You can change it, just be sure to have old newspaper or rags laying around the area where you will work, because a little oil will be lost. The part isn't expensive, for mine on a Ford Expedition was around $35 and took 5 minutes to change. Just un-plug the connector going to the sensor, and a larger wrench will be needed, large (7/8, 15/16) somewhere in that range of size.

Oil gauge

cold oil is thicker, higher rpm=more pressure .factory guage is actually working like it should. if worried hook external guage on oil galley plug and check oil press.manually.

After driving on the highway for a distance and getting off at an exit or stopping for any reason there is a knocking sound and engine appears to be missing. This doesn't happen with town driving or...

check that the oil level is correct as extra oil foams up and the oil pressure falls. Around town driving does not put a strain on the cooling system but continuous highway driving does and shows up as blocked cores and collapsing bottom radiator hoses. Ignition timing is critical at high speeds so ensure that that is correct. Check that the temperature gauge is accurate as the noise and missing is indicative of an overheating engine.

High oil pressure

First thing is find out if the oi pressure is really high. Remove the oil pressure sending unit and hook up a oil pressure test gauge kit, if the pressure is within normal then replace the sending unit first. (requires a special socket)

Why my 2006 xterra oil gauge is all the way up on H? engine sounds good and it drive good....

You will probable need an oil sending switch very cheap part. So I would try that frist. If you start the truck up cold or hot and it goes right up to H. that is what I would do frist.

My oil pressure guage is at the upper safe limit when at idle and tops out when I am moving. Is this a guage issue or a mechanical issue requiring immediate repair?

It could be a bad gauge or a check valve could be stuck or blocked causing your oil pressure to be too high. Have your oil pressure checked at a shop.

When you say pressure appears high, what happens when you remove the cap? Oil spitting out, the sound of z "heavy breathing"?
You say PCV is fine, I gather it shows suction when removed while the engine is running. So put it back.
With the engine idling, remove the oil cap and block off the opening with yout hand. Do you feel pressure then, or suction? Or neither? I think I would expect either neither, or slight ****. In which case, all is good.
