We own a 3.1 also and it's piston slap that's common in those engines. Ours does it too, it's a pronounced knock, not a tick.
the [censored] it is and yes it's a tick,ive replaced 3 sets of lifters now all cured the problem,not pumping up correctly and too much lash.
I didn't mean to word it that yours isn't a tick. I'm just saying that I've heard and experienced piston slap more commonly in those engines than I have lifter tick. I was referring to ours not ticking, but knocking. Didn't mean to put words in your mouth.
