Nissan revised the gaskets and hardware, but it's still a problem. I purchased the EPS oil galley gasket kit because it has improved hardware.

I haven't heard of anyone having hardware issues with the oil pump, so maybe they are different or maybe the mating surfaces are different and it's not an issue. But it has me at least a little concerned.
