Thanks for the reply. Lately I've been running B100 biodiesel about 80% of the time, dinodiesel 20%. I was running straight veggie oil for a while, but not in the past four months or so.

I have not tried swapping the injectors around. This was the first time I ever removed the injectors on the car. I guess I'll pull those two injectors in a couple months and see what they look like.

I do get some whitish-blue smoke on startup that could be some oil burning, but only black smoke while underway, and much less of that with the new injectors (at least one of the old injectors looked like it was a leaker).
