Unfortunately it's very hard to diagnose that sort of thing without actually being able to hear it.
Does it change at all when cold? Hot? High rpm? Low? Things like that help a lot.
Most of the time a ticking is either a valve train issue or a injection issue. A bad lifter will make a definite ticking noise, as will a worn rocker or other valve train issue. Basically anything where there's slop in the valve train.
Try coast down a hill and shutting the engine off in gear (make sure you don't lock the steering) and seeing if it changes. If it's fuel related it will.
Given that it seems to be a sudden onset and related to oil level my best guess would be that you've got a lifter that's failed. But, that's just a guess.

Definitely unrelated, but a failing waterpump can tick also.
I agree with the above.
You may try some auto rx or seafoam. Could just be a clogged/stuck lifter.

I'm still voting valvetrain problem. Have you tried any oil additives yet?

Sounds like a bad lifter. Does it do it cold?
I'd dump a can of seafoam into the oil, run it for a bit under light to moderate load (no heavy load/lugging due to lower lubricity of the oil with seafoam) and then change the oil with some high quality oil. See if that helps.
