Mine was in the thermostatic oil plate. Now it's moving to the stock location via GTM's adapter.

This is first time seeing this thread and the second time I've heard of this oil pressure/oil cooler problem in the past couple of days. Now I'm getting slightly concerned about my 34 row install.

Why get concerned? One poster has an issue that I seriously doubt is oil cooler related. There's not really anything to worry about.

I have a Z1 34R kit and an oil pressure gauge sitting in my garage. My plan is to install the gauge first and get some data over a range of temps and RPMs then install the cooler and compare before and after pressures. I'll post up what I find.

Well mainly because I had seen someone mention this on Z1's Facebook page the other day, and then saw this today.

No need to worry mate I have a 34 row cooler from Gtm and I was gonna chime in to give my data via "Oil Temps" because I've gone on trips and DD but this isnt the case so no worries:tup:

I wouldn't be worried at all, heck us FI guys are also running oil to the turbo with no issues. This pump can handle it.

Thanks guys... Gonna get started on the install today.

Update:
Changed the oil today, put in some Mobil 1 5w30. The oil coming out looked fine, probably still had lots of life left in it. Rechecked everything again for leaks and tightness, still nothing found.

The oil pressure issue is still present after the oil change, if anything maybe even a bit more evident now. Had a weird ticking sound coming from the top right side of the engine, not injector sound something else louder that wasn't there before and kinda a weird smell. Nissan is taking a look at it thursday, I'm pretty in the dark as to what it could be right now.

Valve ticking?

Could be? I don't know my engine sounds that well to tell lol

Update:
Picking up the car from Nissan tomorrow, it has been fixed under warranty. The issue was a gasket that had blown out, in the rear timing chain cover, which was replaced. It caused the drop in oil pressure, not enough to cause anything too serious but enough to notice it with the AEM gauge. Without the gauge, it would be impossible to tell anything had happened unless more of the gasket blew out, to the point where the pressure was low enough at idle to trigger the low oil pressure warning light.

Apparently this has been seen before on Murano's by the dealership, and likely on Z's before as techline immediately suggested this as the cause of the issue to the dealership. No idea what caused it to happen, at least it is sorted out though. If it had been out of warranty, the expense would have been significant - about 20 hours labour!

How are you still under warranty Ed?

That's why it's good to have a gauge for oil pressure. The light on the dash is more of a "replace engine" light than a "low oil pressure" light. It comes on way too late to do anything to save the motor.

He obviously has a great relationship with the dealer. :tup:


FWIW, my oil pressure at normal operating temperature... 82c - 180f

While cruising 300kpa - 44psi

At idle 150kpa - 22psi
