Alright, I'll probably order parts this week and possibly do the job next weekend.
I have the MB-WIS DVDs and i'm sure i've seen instructions for replacing glow plugs, those'll probably have the part# for the reamer; is there a specific anti-seize i should use?
I figure i can R&R the intake pretty quickly seeing as i've already learned the hard way how to put it back on

, but i don't think i'll run the engine w/o the manifold (the last time it was off one of those little plastic retainers broke off and fell into a runner, luckily that cylinder's valves were closed!) Ouch that would hurt!
