2010 g37xs with 80k miles serviced regularly and premium gas always used.

Heard this ticking noise, very consistent in nature, noticed it at idle after parking car.

Videos are crappy sorry but its a distinct ticking noise. What can it be? You can hear it more in video ticking 2.

 

bump........

 

Sounds like a motor making normal noises to me

 

can not make out any abnormal engine noise in either videos

 

Seems similar to all VQ's injector solenoids. I remember my 99 Maxima having very loud ticking.

 

normal, but i guess you are a perfectionist haha

 

Sounds like the lifters to me. Do you have enough oil? What kind of oil filter are you using?

This might help:

I can hear the ticking pretty clearly. It's likely play in the valves, but I'm hardly a mechanic. Does it increase with RPM's?

 

I had that in my VQ. It is not constantly there, but sometimes it sounds like a lifter sticking. Since you are already at 80k miles, I would switch to Synthetic High Mileage Mobil 1. I used to like Penzoil Ultra and Platinum, but VQ tends to not like these Penzoil oil. My issue was both my VQ35HR and VQ37VHR were prone to Valve cover oil leaks. Oil does not leak a lot (just damp or weep) but If you look around the valve (camshaft cover) where it meets with the engine block, there is 99% chance you have that issue at that mileage.

The driver side is prone to that than the passenger side. The VQ35HR already has 85k miles and before my extended warranty ended, I asked them to fix it. Currently not a single oil dampness in that area. ( Using Mobile 1 HighMileage)

The VQ37VHR, had some small oil weep on the driver side as early as 8k miles! That time I was using Penzoil Ultra Synthetic. I cleaned oil residue with few spray of engine cleaner and switched to Mobile1. So far both engine are clean of oil leaks.
