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.

What are the EPS gaskets made of? Synthaseal? I bought a used pump for dirt cheap to see what size the screws are on it. I can confirm that the screws are grade 7 (old spec) or grade 8.8 (new spec) M6 x 15mm screws; they are 1mm longer than the screws CZP provides. CZP screws are also weaker than the stock screws, which explains why I read some members saying the CZP screws strip out.
