After 4 years of completely silent bb30 use on various carbon bikes my synapse hi mod has started clicking when the right crank arm is at about 1-2 o clock.
1. Only happens under load, nothing at all when soft pedaling
2. Happens in both the big and little rings
3. The closest I can describe the noise is when your right crank arm catches the front mech cable ferule if the cable is too long, but that definitely isn't happening
I've got all the tools to take the cranks off (except a 40nm torque wrench for reinstallation), and a bb30 press. Shall I strip it down and check everything is kosher or are there ways and means of diagnosing the problem before that process?

If your BB30 is doing that, then there is nothing to diagnose as such: it needs to be stripped down, cleaned and reassembled.

If it's four years old and you're taking it apart anyway, you might as well sling some new bearings in.
