Valve covers started leaking, so I decided to replace them + spark plugs and made this video. This is on a VQ35HR but the process is very similar for the VQ37VHR. Hope this is helpful to anyone taking on the same project!

The main differences:

1. No VVT or CAM Sensor on the VQ37 valve cover.
   
2. You’ll need RTV on the front and back corners of the VQ37 when reinstalling the valve cover.
   
3. The VQ37 has replaceable spark plug gaskets, so you can replace those without needing new valve covers if they’re in good condition.
