It happens like this. Tick tick tick tick normal normal normal normal tick tick tick.
However the hotter the engine gets the faster and less loud the ticks are.
My car has only done 900km.
I'm not sure if theres a issue with the cat's or its the VVL system ticking over.

I'm with EVL370. The VVL system, or just the valvetrain in general. My '09 FX35 doesn't make the noise, so I'm thinking it's something with the infinitely variable system on the VQ37 vs. VQ35HR. I really believe that's why Nissan would like us using the Nissan Ester Oil. It must diminish that sound, though I've been using it since day 1, have 16,300 miles, and I still hear it at idle. Tick tick tick tick... One tick per revolution. It's a little noisy from the outside, but she runs just fine. I'm not worried.
I believe this is what the OP could be talking about. AK, I have the ticking cats as well. The 370 is a machine of its own. With all of the noises, everything still works the way it was designed from what I have gathered so far.
