Mine was there all the time for the first 1000 miles or so, but has become very intermittant...probably there 25% of the time now. While I was having some TSB's done at the dealer I asked them to listen for the irregular ticking/knocking noise. They heard it but considered it normal.
I tried 5w-30 at a 900 mile oil change and it didn't make a difference
You need to be sure that you're not confusing the fuel injector ticking with an abnormal noise though. The injectors will tick constantly, it's normal. What I'm talking about is an irregular light knocking or clacking noise which sounds just like a sticky lifter...and only there at warm idle, AND only below 1200 RPM. It can't be valve clearance, but it could be an erratic valve, or possibly the variable valve timing.
In fact, in a Kia press release for the new 2.4 direct injection engine, they mentioned a "quieter and more durable" variable valve timing system for the new engine. Hmmm.
