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