I don't think the 4x4 has cam bearings at front like 2wd has.
Most likely a lazy tappet, make sure it is coming from here and not a dry bearting in the timing belt tensioner as mine was, going tappety click click.

Spray a bit of wd40 on the tensioner mate to see if the noise changes, also is it on start up or when its hot, maybe a bearing, small end?
how old is your oil and what grade?

If you are getting any noise from the tensioner that is not caused by the rubbing timing belt, I would change it, mine was dry as hell and made a scoring sound when spun and click click when cold especially.
