Finally changed the banjo filter today. 120,000 miles with Valvoline 5W-30 full synthetic every 4-5K. Some debris in there but don't think I was near turbo starvation.
Also, just to confirm for peace of mind. The bolt doesn't have directionality, correct? (i.e. the hole in the bolt doesn't need to be inline with the oil line?) I hope not, as I don't want to have to take it back out.
