I had an oil filter that was seized, so I had to remove the entire assembly. When I put the assembly back on, oil was leaking through the banjo bolt, as I damaged the crush washer. Does anyone know what size crush washer goes on that bolt? realoem doesn't show anything and I can't find a DIY anywhere. Seems like a common repair. Also, when removing and re-attaching an oil filter housing assembly, do I need to add new gaskets each time or only if there are damaged/old?

Rubber parts harden/deform over time, go with new to prevent leaks.
I would change the two o-rings. Item #2 & #4

Banjo bolt torque is 35-45 NM
Scope creep-
There's a kit(#7 pn 11429059338) for the oil cooler valve that comes with an o-ring. I'd change that out too as it'll eventually leak. Easy to change out while the housing assembly is off the block as you need to compress a spring to re-install the snap-ring.
