The sound you're hearing is normal. You're more than likely hearing piston slap. If you ever see the stock pistons you'll understand more why you hear the slap. The skirt on the piston is virtually gone. Mine had the piston slap noise when it was stock and it's doing it with the forged lower compression Mahle pistons I have now. Once my car is warmed up it goes away as always. If your "ticking" sound never goes away or it becomes a "knocking" sound then you should worry but nothing is wrong as of now.
