Pulled leaking injector has/had no seal!!

[vtchequers]

Managed to pull my leaking injector from my Peugeot 307 diesel. I was hoping the seal would come out with the injector, which it didn't. Anyway, took a look down the hole with the use of a torch, and there's no seal down there what so ever! not even a fragment!!


Questions-

If there "was" a seal down there, is it possible for the seal to disintegrate? if so, could the bits have caused any damage?

I wouldn't have thought it would disappear, the copper washer usually stays put. The plastic spacer can get eaten though - but most of it remains.

As Steve said, the only seal that should be in there is a copper washer at the very bottom of the hole and it is quite normal for them to stay there after an injector is removed.

The plastic spacer was a bit clogged up but ok. I'm thinking it was repaired/replaced some time and someone forgot to put in a seal (washer).

Be very sure that the seal is missing & not just stuck at the bottom of the hole.
It can sometimes be very difficult to see them if the area is covered in the black gunge associated with a failed seal.

Everything, including the injector, has been cleaned. There was definitely no sign of a seal down there.
