Neither did I, especially after I used the proper tools to properly torque them + additional dabs of Nissan RTV for assurance.
Update on the issue:
I've been driving with an analog OIL psi gauge out of the hood for some time now.
I notice that my max pressures can hit up to 130-140psi when cold and accelerating.
Max psi while warmed up is 100-110psi after 3.5k rpm.
I get dips of 15 psi that follow VTC operation, seeing higher pressure when the VTCs are stuck at zero which makes sense.
I can avoid the p0011 if I maintain higher than 3k rpm. If I stay between the 1500-2500rpm I get pinging from retarded VTCs - Pressures during this RPM is over 30psi.
I still get 14-15psi at 650 idle sometimes dipping to 13 on rare occasions.
Once I pass 3k rpm the engine runs/sounds normal and carries the power to red line if I wish to push it.
I will try another oil filter soon and lastly different oil at one point.
