If it is a true engine knock then it is likely oil starvation or piston slap. Some folks hear "pinging" as engine knock but this is actually mistimed detonation in the cylinder caused by low octane or bad timing or other related tune factors. There is a theory out there that the 3.0 Nissan motors had some piston slap but I have not seen validation in my little world yet. My 3.3 is extremely quiet at 155,000 KM
