Well I'm taking this preparation a step at a time -- today I adjusted the valves. Every one of the valves was tight -- I couldn't get a feeler gauge into any one of them before adjustment.

Now it seems that I need to re-adjust rack damper bolt and idle, since I adjusted those some time before I did the valve adjustment, and now there seems to be a little dip in the idle after letting go of the throttle.

I believe next up will be professional injector cleaning/test and most likely nozzle replacement for each injector -- I'll let the diesel injection shop decide when I get to it.

The shop I'm going to try here is Garden State Diesel, which is a Bosch-certified diesel injection shop. They quoted me $20 per injector for testing, and if nozzle replacements are needed, they told me they waive the testing fee in that case. We'll see how it works out.
