Isolate the location
You need to try to isolate the location of the noise. If you have a long screwdriver, it can act as a conduit for sound. Put it tight to your ear and touch the other end against the valve cover on the side the sound seems loudest. If you can't hear it more clearly then, try different locations (intake, top of the front cover, wherever you can reach).
This has to be done with the motor running, so be CAREFUL of loose clothing, hands, the screwdriver listening device, etc.
Unfortunately, I suspect you have an expensive "tick" rather than a cheap "tick", but localizing the source will help determine this.
If this doesn't help identify the source of the sound, try to add an additive like SR50 or any "quiet" additive that works on the oil. If the tick then goes away, the problem is internal engine wear.
I would do these things before seeking to start replacing parts, paying for tuneups, or adjusting anything.
