Newbie doing injector seals on a 2010 Mercedes 3.0 v6 CDI, few questions please .

Hi, I recently bought a 2010 mercedes 3.0 V6. The injector seals need replacing , it's ticking and can actually smell and see it leaking.
I've never done this job before but I have done a lot of other car repair jobs . I'm really prepared and willing to take this on .
I Know the seat has to be recut, how do I know when it's cut properly , I don't want to overdo it and take too much metal off it something .

Do I have to set the tool to a certain depth , if so what should it be set at ?
Does the tool have to be set at a certain depth, if so then at what ?
I would appreciate any other bits of advice you might have about doing this job. I know to use a hoover to get out any metal shavings etc that are inside .

I've seen a video on YouTube and I think I can do this , but some parts about it confuse me a little.

the fuel specialist says it'll be about 4 hours to do and £200 to get this job done , I assume that's for all the seals and not just the 1 ? I forgot to ask

Regardless I'd rather do it myself, I want to keep on learning

Many thanks to everyone

That would qualify for diesel section, where you will get more exposure, since the OM642 engine was mounted on dozens of different models.
Finding diesel W212 owner on this forum will give you count, where fingers on 1 hand are sufficient.
Do your homework as the job doesn't have to be as easy at it appears. The phenomena is often called "Black death" so google it.
and good luck.
