Hopefully the injectors won't be hard to pull out this pass. Seems the biggest risk is buying a car where it leaked too long and an injector simply can't be removed. All I know is from Rollguy's prior posts. It looks like the main design issue is that they use just a single side bolt to secure each injector, compared to a monster thread in my older OM617 engine. That likely made factory assembly much faster, but not so for the guys who must maintain these. One must use a metal pressure seal, given the pressures and temperatures, so it is critical to apply even loading to get a good seal. Perhaps the single side bolt allows slight cocking in the bore.

I’ve seen videos where the repair also included a reseating tool for the injector hole , this before the washer placement .I think it’s a very lite resurfacing of the bore landing , when the washer is wasted all that pressure and is on the seat possible slightly wearing on the surface.

That is correct, there is a tool used to "clean up" the washer seating surface that is like a small milling bit that you use by hand.

Seat resurfacing
I think that is why the same injector seal is leaking. I must not have gotten the seat as clean as I should have. I think I might invest in the tool for resurfacing the seat.......Rich

Tool is not very pricey and I suspect should be used anytime an injector is pulled.

I started the job today. After chipping and vacuuming the tar away, I was able to remove the worst injector with some major slide hammer action. The seal had a spot on it that was definitely leaking. I cut the seat with the tool I just got, and it seemed to work okay. Once the bores and seats were cleaned, the injectors get a coat of ceramic grease. I am having an issue with the bolt bores. It seems that there is some gunk down inside, as three of the bolts seem tight before they contact the clamp. I need to get some carb cleaner down in there to loosen up the grime, and then blow it out with air. The entire job will take about four hours.

I'd forgotten about screw holes. They have to be as clean as injector hole.

Thanks for the excellent photos and info. Not that I'll ever have an E320, but very interesting.

Yes, one of them I had to use a drill bit to get the carbon and other debris out in order to be able to tighten the bolt to 7 NM + 2- 90 degree turns. Before cleaning out the bolt hole, there was about 1/4" gap between the surface of the clamp and the bottom of the bolt (used, not new) head with the bolt as tight as I was willing to tighten it. Working the drill bit, compressed air and PB Blaster got the hole cleaned out enough to allow the new bolt to tighten properly.
