Well, I've been out for a long (40 miles ish) drive, mostly 60-70mph, so it got properly warmed up.

Even after that, its still noisy at idle. But I'm not worried about that as I know it will all settle down and I have a 90mile per day commute so it wont take long.

I am worried because the top of the pump is still a little wet, although it looks to be more just beneath the injection line nuts than anything else, and when I lifted the bonnet (hood) when I returned home there is still a small amount of diesel burning off in a visible cloud. I didnt bother drying it after working on it as I assumed this would all burn off in a few miles. Do I just need to wait longer or is likely theres still a leak somewhere there? It seems starnge that all of the injection lines would leak.
