Threw a P1688 today and went into limp mode after a noticeable hiccup at steady highway speeds. So, I’m fairly certain I need a new harmonic balancer and will be ordering the ATI Super Damper from WMW in a second. What else should I consider at the time? Definitively replacing the crank seal, and the belt. Should I also do the water pump now, or can that (should it) wait, knowing I’ve got a supercharger to replace sometime in the future? Is there anything else that should be handled simultaneously? 81k on a 2006 JCW.

Belt tensioner, idler pulley, camshaft position sensor o-ring, and there’s a bolt with integral o-ring that sits behind the crank pulley (p/n 07131485184) that I’d replace.
