UPDATE
As others have said, it all appears fine, however, I did post a while ago that my PD oiler ran out of oil, and it was a bit silly of me not to check it and top up, however, noticed that fresh oil was not getting on the chain after topping up, thought maybe needed bleeding, so tried this morning, only to find oil running down OUTSIDE of tube, on closer inspection, I must have cracked the pipe when doing the work on the backend of the bike, as there was a split, oil was running down on to the suspension linkage (which I thought was just fling off the chain), cut the tube back, and lucky enough had enough to reach again, all seems working again.
there's a moral here somewhere, but cannot think of it
