Injector seals leaking (again)

[Uncle Fester]

Hi all, I'm looking for a little advice here, as a second seal has started to leak/let by.
I had the front one done by a local diesel specialist at a cost of £320 and although it fixed the problem (for now) I was kind of expecting them to clean the carbon residue off the entire area, but they only cleaned the injector they worked on.....
Anyway, less than 2 months later (about 2000 miles) another seal is letting by, and frankly I'm loathed to take it back there as their costs seem a bit high, and I certainlay can't afford £300 per seal to get the other three done.
So my question is, what do I need to get (tool wise) to do the job myself?
I know I will need and injector removal tool, and either a seat cleaner or re-seating tool, I would like some advice on what are the best tools for the job.
Also do I need to buy the MB white grease for refitting the injectors, or will copper grease work?
I know that I'll need to replace all bolts, clips and copper seals, I just don't want to buy tools that are not up to job.

Have seen these:

Thanks in advance for your wisdom.

If the seal has only been blowing for a short time then you may not have much trouble removing the injector, I resealed one on my e220 over a year ago now that had black crud up to the fuel rail pipe and it came out with very little effort, wriggled it out with an adjustable spanner. I bought the seat cleaning tool from my local Merc dealer along with the correct grease which came to about 30 quid I think. Don't use copper grease is what I was told. Took me an hour from start to finish and so far it's done the job. I take the covers off the engine once a month just to check

Thanks for that, I have a keen nose and smell the fumes coming into the cabin, I only use the car at weekends as I have a company vehicle, so I think it's only been letting by for about 4-500 miles.
I have read that cleanliness is parramount, and so I'm a little concerned about the crap that may fall into the cylinder bore, or is this only likely to be carbon?

Hi Fester, i normally do all my own repairs but after reading all the posts on here about what may go wrong when you take on this job i decided to bite the bullet and took my 320cdi down to olly and jack at pcs.They done all 6 of mine for a lot less than you paid originally.

I stuck a thin plastic tube onto the end of the hoover pipe, there are little plugs in the cleaning kit that stop crud going down the bolt holes. I cleaned off the crap around the injector first, took the clamp off, plugged the hole and then removed the injector. Didn't have any problems with screwing the new bolt in then.

Had one of my injector seals leaking, after reading all the bits on here got the garage to do it. £30 all inclusive. Result or what:bannana:

I had mine done by a regular garage who, in hindsight, didn't know what they were doing, despite the fact that discussed it all with the chief before he gave it to the boy to work on, and they made a complete baws of it.
They nearly wrecked the engine and I had to get inserts fitted in the injector clamp threads.

I'd recommend getting a proper MB indy to do the work, but if you are doing it, cleanliness is essential.

Like the previous person said, you need to meticulously vacuum out the bore, you alse need to clean the threads using the appropriate tool, and use a reseating tool to ensure a good seal.
I hired mine from United Diesels.

The grease is a special high temperature material too.

Hindsight is a magic thing, so I hope it helps you.
