Spent an hour or so on it today, renewed the oil sealing washers, took the water banjo off completely and renewed the washers on it and the spacer (which I didn't do last time so I think that was the source of the leak)
Tapped out all of the threads for the turbo bolts and got a bit of swarf out of the offending hole, looks like I was right and something was in there; probably something from work while I was getting the studs out. I also ran a die down all the threads on the bolts so everything screws in easily now. Manifold and nuts are also back on but not tight, will sort that next time I go up there.
Will be rocking in the missus Seicento for a bit longer lol
Ordered some amber LED bulbs and bulb holders for the side markers and taking the rubstrip into work tomorrow to mark out and cut the side markers into it. Will also take my hubs in to press the wheel bearings in too
