I'm slowly plugging away at making my old 2.25 more drivable, and to that end I spent the weekend putting in four new injectors and upgrading the old series glow plugs to the newer parallel wired type. Along the way I discovered that whomever installed the last set of injectors only put the copper sealing washer in one cylinder, and didn't put the steel sealing washers in any of them.
In any case, I'm now more confused than ever as to the diagnosis going forward: before I did the work on Sunday, she started very easily, sounded awful, and blew light blue smoke until very warm, at which point she started making a little bit of black - all of which I'm told means the timing was probably too advanced. Now she's hard to start, sounds slightly better, and blows clouds of white smoke until she's thoroughly warmed up, but has a ton more power (whee!) - which I think means the timing is now probably too retarded.
Thing that's confusing me is I never actually touched the timing. Could new injectors (and the addition of proper sealing washers) make that big a difference? Or am I missing something obvious?

Separately, my old glow plugs were on a 30a fuse. The new ones (from the 2.5) apparently draw a touch more than that - I had to jump around the fuse with a bit of wire to get her started. Anybody know from experience what they actually need, or should I just rewire them to draw straight from the battery?
