Hi all. The injectors were removed from the same engine... how comes that the first one has a kind of gap around the nozzle where the washer fits and the other has like a seal??? the other 3 are all like the first one with the gap , am i missing something???

Have you looked up the part number and found new ones to compare?
Have you looked down the holes they came out of and found 4 seals there but not one in the one that came out with one?
Very bizarre!!

If you look at this.

www.discovery2.co.uk / TD5 Engine - Injector Seal Replacement

you'll see that the end of the dirty injector that he shows you is like the one you have with a central seal type thing, not like your other 4.
Are all 5 the same make?
How was it running before you pulled them and did you do a diagnostic first? (Stoopid question, I know.)
Best of luck with it.

Bizarre indeed... the pics came from a friend of mine, the pics are after he removed the old washers, i dont know much about these things cos when it comes to such jobs i pay my mechanic... i searched a lot by p/n and didnt find a pic from that position

I had a quick search, not by part number, just a generic search for "injectors for TD5 engine", and like you didn't find a good pic of the bit we both want to see.
Hopefully someone else who has taken them out will know.
But if it was running fine before??.....

Mystery solved after a divine intervention ... that black "seal-shape" thing was petrified carbon deposit, the one with the gap is normal ... it was injector nr.5 so the missing glow plug might have some effect too.

Was going to say, there's normally just a load of crap around there!

The oddity was that looked like factory fitted and was rock solid while on the other 4 was completely different and softer like this

Yes, you're right, it does seem to be number 5. Mine was exactly the same and fortunately I broke it "by accident" then realised what it was!! I don't know if the 2000 Td5 has them but the cylinder numbers on my 03 are visible through the spyhole on the top which made setting the injectors a lot easier.

I dont know such mechanical stuff but isn't the numbering through the spyhole about the firing order? i said injector 5 meaning the last from front to rear where there is no glow plug... it's good to know though how carbon can behave in such cases

Sorry, yes, that's what I meant re the firing order, it's much more accurate than trying to set the position by "eye". It must be that the carbon behaves differently with no glow plug present. I'm retired now but was used to dealing with tractors and diggers where the amount of carbon present in those engines made what it was much more obvious!!

Fascinating! So glad you found the solution!
