The light tick like that is typically from a pitted or damaged roller on the lifter. When this happens it wipes out the cam lobe. To check it use a stethoscope or screwdriver on the rocker bolts to identify what one makes the noise. Then use a dial indicator just like I do in this video https://youtu.be/0YPPsYbffAA and at 9:50 is when I used a dial indicator. It's fairly common on the newer direct injection engines because the camshaft is such a soft metal. Hopefully I'm rong for your sake. If I'm not though, you may as well do a full delete at that point.
