What Classifies As Low Oil Pressure? 2010 370z

I honestly would recommend a new engine to be swapped at that point. There's no doubt that you started wearing the bearings with such low oil pressure. No point in doing gallery gasket now.

How likely is this to be a problem?

How much more work is it to check for that, while doing the gallery gasket work?

I had Nissan do a pre-purchase inspection on the vehicle before I purchased it from another dealer. The Nissan tech said the engine felt/looked very healthy, and the compression checks were great.

You would have to take out a couple bearings and see if they're still good, but at that point you might aswell change all the bearings and in the end swapping in a newer block is cheaper $ wise.

Edit: The reason I'm saying this is I had a friend's car that we did the gallery gasket on. Oil pressure was a little higher than yours but still under 13~ psi at hot idle. His engine is still running but the oil is glittery with every oil change.
