Default 2006 Pathfinder LE, Low oil Pressure at Idle

I read the article about the 2005 Pathfinder and still didn't see if anyone found a fix. So basically I purchased this vehicle with 122,000 miles (now has 128,000) and notice the pressure gauge was maxed out (sending unit had gone bad), so I replaced it myself and everything was fine. About 2 weeks ago I changed the oil myself (pennzoil platinum, with a purolator filter). A few days later I was at a stop light and my oil pressure gauge needle caught my eye, it was bouncing up and down, but continued to inch down, but not to the point where it would set off anything on the instrument gauge. Light turned green, needle goes back to the half way point and stays consistent until next red light and same thing. Next day I paid attention more and noticed this only happens after driving for a period of time allowing the oil to heat up. I called my friend down at the local Nissan shop and said replace filter with OEM and start there. Changed it out 2 days ago and still the same. Anyone found a fix yet??

Did you replace it with a genuine Nissan oil pressure sender? I've heard of a lot of problems with the aftermarket replacements.

Yes I did replace it with a aftermarket one, my father being a sales rep in the aftermarket business makes it hard for me to buy from the dealership when I can get parts for hardly nothing, but my friend at nissan, his next question was the same you ask. Once I replaced the oil sending unit everything seemed alright, changed it about a month before I seemed to notice the oil pressure going crazy.

I have a 2006 pathfinder have the same problem these past 3 weeks brought to mechanic and the 2 silicone gaskets behind the timing belts are bad had them replaced $2.200 along with the tensioners and other gaskets as it is alot of parts to remove got it back drove it 2 days still the gauge goes down when at idle mode in park or at a red light.
i have it back at the mechanic now will post you a update as i have replaced everything gaskets,oil pump,oil pressure sensor. could be i bought a defective part i dunno yet. by the way the gaskets behind the timing chains are built into the actual plate that covers the front part of the engine $625 just for that alone but i was forced to buy it it was the only way to get gasket.

Thank you for the info, it's crazy all the work and still didn't fix the problem, and I've read other post about pathfinders and other nissans with the same problem, and for some to say it's "normal" is hard for me to swallow. If I had a piece of mind knowing the vehicle is alright and it's just a "glitch " then I'll just forget about and continue to enjoy the vehicle but I'm the kind of person who gets bothered then anything needs to be fixed on my vehicles.

Yes it is fixed it was the gasket behind the timing chain cover the gasket is built into the entire front plate of the engine ans was the cause of the oil pressure drops. i went as far as replacing the oil pressure sensor and the oil pump itself to cover all bases even the water pump to as it sits now inside the front plate. Some bullshit nissan engineering every mechanic i talked to said the same thing nissan really screwed people over when they engineered where the water pump and timing plate gaskets good luck and thank you for asking as i lost this link to reply

It is a big job and alot of work and you are stuck replacing other gaskets because they have to be removed to get inside good luck

The water pump isn't so bad of an engineering design. You can replace it without removing the front cover via the access plates. The nice thing about have the water pump driven by the timing chain is that with an all aluminum engine, you really don't want to overheat it. With a chain driven pump, the coolant will be circulated even if the serpentine belt breaks while driving. You essentially can drive the vehicle without the belt as long as there's enough juice left in the battery to run the engine and as long as you can "man-handle" the steering without power assist.
There really aren't too many "modern" engines that are easy to work on nor have any problems.

Possibly... A cam or crank position sensor would do this. You'll need to get the code(s) retrieved.

How hard would it be for an at home mechanic to replace this gasket? Or about how much would I be looking at if a shop does the work? Have spent 3000 on my pathy due to timing chain breaking and doing some damage to valves and heads and all else that entailed. Car drove fine for the first week or so after I got it back and then started having oil pressure drop once let off gas and car was at operating temp.

"How hard" is something I can't answer as I don't know of your mechanical skills nor what tools you have. It is not an easy job and is a time consuming job, as the front cover and timing components have to be removed to even access the rear timing cover. At that point, you can remove the rear cover to access the seals. You would need the ring gear stopper to do this job, which is a tool that is getting hard to find, to do the job without having to remove the upper plenum and valve covers, which adds more time and expense. Here's a link to a part diagram to give you an idea:

As far as price to do the job, your best bet would be to get a couple of price quotes from reputable shops in your area.
