I thought my giant revolt was 86.5mm so I didn’t need the spacer. However it looks like I do since the left crank arm doesn’t sit flush in the axle. The gap is around 2-3mm and the spacer I ignored was 2.5mm so it’s pretty obvious I think I should have put the spacer in. Am I fucked now the BB has been pressed in?
I know you can press out the bearings and replace them, but the spacer is supposed to go between the bearing cups that thread together in the middle. Can it be salvaged? And will the bearings be okay when I inevitably press them out?

You need the appropriate press adapters for it, but you can remove and re-use PF cups.
How would a spacer on the BB help here?
It looks like the BB is too wide – your spindle should be coming further into the crank arm. If you add a spacer anywhere on the BB, it’s going to pull the spindle even further back, because the width of the BB will increase.
I can’t picture how installing a spacer anywhere here would help you, but maybe I’m missing something. My guess would be you haven’t got the BB pressed all the way in, or it’s the wrong BB.
