Both. :(

Well what’s weird is it’s got the same power still pulls hard all the way through the band even between 2-4K, the noise, (not pushing it like I used to but I had to see what would happen) and heck just switching to the redline after this noise started has made it smoother.

I think my next option is to find a decent oil pressure gauge.

Yeap, If I had to guess the oil galley gaskets would be the culprit.

My thinking on it. At 2,200 to 4,000 rpm. He should have about 50 ~ 60 psi. That maybe what is needed for the VVL and Varivalve timing to operate there. Not enough oil pressure and things get noisy. Once he goes past 4,000 rpm, oil pressure goes up, and things quite down. He may have enough oil pressure to operate everything above 4,000 rpm's. Might have just enough of a leak to cause an issue between 2,200 and 4,000 rpm's. If I'm right. He maybe be catching it before the real damage starts. Won't know until he mounts an oil pressure gauge.

Remember to get one that reads from 0 to 150 psi.

Will do just gotta figure out how I want to do this setup I don’t really want to end up with a bunch of gauges so I’m looking at a pressure and temp to swap in.

Eh just going to get a good standard oil pressure gauge.
Rusty I have seen some debate on mechanical vs electrical, which one do you recommend?

I can tell you from experience that a mechanical gauge can leak ... inside the car ... all over new carpet. An electrical gauge is usually easier to install (don't have to worry about kinked tubing), just as accurate, and won't leak.

^^^^^ This.

:iagree:

When you install the sensor. I would install it next to the factory sensor.

Here's a link to the same tee I used.

Here's a link to the install.

I started a thread about oil pressure. :tup:

Awesome, I’m ordering one now so hopefully I have time this week to install if not it won’t be till next Saturday. I’ll update as soon as possible I’m ready to solve this.

4-5 week build time, didn’t notice it at first but I liked the price and the customization of the speedhut 0-150 gauge. So until then hopefully nothing gets worse and I’m going to do frequent oil changes. Unless I get the courage to open up the front cover.

Did you get the one with the warning light?

that sounds like there is something lose in the engine bay, hitting that engine.


i mean yeah it does sound like a valve, but i think something is loose, i listened for like 10min and ruled the valve out.

Is it louder by the valves or by the crank? I've had an oil galley go, it made it so the engine couldn't find idle without that oil pressure, so it would surge from 1000-1500 rpm in rythme. After Nissan fixed that, the car had a rhythmic noise like that coming from the bottom end all of the sudden, only on throttle. I thought it was an exhaust leak, turned out to be a spun thrust bearing. Engine seized a few months later.
