The valves don't need adjustment like solid lifters do. They don't go out of adjustment, because they are hydraulic. If you have one ticking, it's more than likely sticking, or a lifter going bad. Of course, it's very possible the cam lobe is also going.

Let's hope it's just sticking. They make some stuff called top engine cleaner. I've never used, only heard about it. It's supposed to help this I believe. I've also heard you can add some Marvel Mystery oil to help with things like this, if indeed it is sticking. Worth a shot I guess.
