The ticking would be the VLA's (Variable lash adjusters.?)
There are posts about replacing them, might as well redo the valve guide seals too. (yours must smoke and burn a bit of oil? typical) I got mine off ebay for around $60
Or you could just leave 'em! It's more annoying than anything.
Here's a seal replacement thread (http://www.4x4wire.com/forums/showflat.php?Cat=&Number=728034&Main=679888), The VLA's are the things with the little holes in them above the valves in the picture.
Good luck!
