Injector Seal part number?

[Larry & Norma]

Does anyone have the current part number for an injector seal ring please?

Thanks Naj but the Mercedes parts site does not recognise that number.
Mervyn at Poole has sorted me out with some only 3 in stock but will get me out of trouble.
I discovered 3 loose injectors and found none have seals!!
Must have been running like this for some time (i've done 3k miles since owning the car for a year)
So last minute panic before France, I was worried that perhaps the threads were stripped but
they seem ok phew!!
Hopefully idle will be even smoother when done as air must have been blowing by.

Hi, Larry,

A 14mm ID x18mm OD (though not critical) from a motor factor's box of copper washers would do just fine.

I just popped down to my local hardware supplier with an used seal as an example and found matching ones far cheaper than the MB dealer.

Same applies to the copper seals for the valve cover...

I did not have a used one to do this as all were missing
FYI I managed to get all 6 from Poole, the official ones are aluminium but I guess copper is
just as good.
All injectors were loose, I could wiggle them by hand so they need the seal to form
a good tight hold.
I would think the constant expansion and contraction of the dissimilar metals over the heat cycle
caused them to become loose without the seals being present.
Strange thing is it has made no difference to the running of the engine as far as I can tell idling.
Will go for a run later if it stops raining and hope at least the faint smell of petrol has been fixed.
