Every engine I've heard that later turned out to have a crank or rod bearing problem made a fairly regular heavy thunk or knock that follows engine speed, not something you'd describe as a 'tick". You will also often have a low oil pressure situation due to excessive clearance.

The audio posts I've heard of the BBQ ignitor-like tick sound lighter, without a sense of mass and are much more irregular that the rod/crank knocks I've heard. There was another post (I think on another forum) where this tick was allegedly traced definitively to a scored cylinder wall. Both main bearing and piston / cylinder work involve a lot of disassembly, so another cause cannot be discounted.
