Low oil pressure!

..A copy a paste from the my350z forums when I had the issue

If the sensor doesn't solve your problem (usually a bad sensor just hits the rail)... then plug in a gauge and check the pressure. The gallery gaskets underneath the timing covers could be toast.

I have an HR motor and I had a similar issue. The factory gallery gaskets on the 350zHR and 370z were paper. They eventually just separate. Luckily, there is an infinity part number (now available as a nissan part number) for metal ones. In the past, you had to replace the entire timing cover. Even though the stand alone gasket is cheap, The labor is expensive.

Oil analysis came back perfectly fine, so im thinking oil galley gaskets. Has anyone seen oil galley gasket issues on later models? (post 2012) I'm open to suggestions before i decide to rip the the rear timing cover off.
