Hey I'm recently back in the pathy world, although this time with a '97 QX4. I've got a nice oil leak at the right valve cover that is burning up on the exhaust manifold. Any write-ups or advice before I get my balls wet? Anything else I should be doing once I've got it that far apart? Thanks dudes

The right bank is really not that bad of a job; it's the left bank that's a pain because of the upper plenum having to be removed. Unless you have hydraulic lifter issues, really nothing else to do while you're in there.

I replaced the gasket today, an easy job for sure. When I started in I found that the screws closest to the front of the engine were finger tight at best (I assume this is why it was leaking) but I had already bought the gasket so I changed it anyway. I also pulled off the tube in front of the butterfly valve, hosed it with carb cleaner and fixed the sticky throttle. Cheers.

That's common as they do loosen up over time. It's not a bad practice to tighten them up (at least the ones that you can) at every 30000 mile service.
