The oil pressure drops...

The oil pressure drops when idling. 2006 exterra

Mechanic's Assistant: How old is your oil pump? Has the check engine light come on?

Oil pump is ( I am assuming) original. No, but just had (i believe) left side catalytic replaced due to failure and disintegration.

Mechanic's Assistant: What is the model of your '06 Nissan?

Xterra

Mechanic's Assistant: Are you fixing your Xterra yourself? What have you tried so far?

I just recently replaced ignition coils and plugs myself. The Cat. was changed by mechanic.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Oh ya I replaced oil pressure sensor myself as well.

Hey there, thanks for the question.Does the oil light come while idling? But go away as you accelerated?

It drops pretty low, but light hasn't come on yet. It returns to normal pressure when I accelerate
There really is only 2 idle oil pressure issues I see on these engines.The first being the rear timing chain gasket leaking at the L cover that runs to the IVT solenoids. This causes oil pressure to bleed off at idle.The second being the upper secondary timing tensioner failing and bleeding off pressure.Both of these are really big crappy jobs to be honest. Both are a concern, but I have seen people drive EXTENDED periods of time with them with no ongoing issues if the oil light is not on.

Okay thanks. Your info is fairly consistent with what I'm finding. The vehicle is under a extended warranty which would not cover the gasket, but possibly the engine failing. I guest I will have to take my chance.
Yea, I wish o had an easy fix on this one but unfortunately I don’t see any other causes for you specific symptoms on these engines. Also when the oil pumps fail they generally make a weird hum or high pitch noise when the engine is Reved up.

I haven't heard any noise from pump. Vehicle seems to be running fine other wise. I've seen on line that using a thicker oil helps. Any thoughts on that?
Customer reply replied 3 months ago
Also it was my intention to pay for only a 1 time session and was wondering if you could assure this is what has happened or do I need to cancel something some where?
Thicker oil will increase pressure very slightly. It will also probably increase gas consumption a little bit as the engine is less efficient.

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
