16v 4age injectors

i just noticed my injectors are leaking. is there supposed to be a rubber spacer/seal at the base of the injector where it seals on the head ??

i noticed my 4agze injectors have them but my blue top doesn't
if they are meant to be there, where can i get them from?

Farkin expensive little critters tho Better to scavenge some used
ones off old injectors if you can. And you can get new o-rings for the
top of the injectors from an industrial supplier... cheap as chips

sweet just stole the ones off my 4agze injectors - i'll be upgrading them as part of the turbo build anyway so doesn't matter.

bluetop is running alot better now. pretty weird though as its been like it for the last 2 years or so and its only just started leaking now...

Those rubber rings are a spacer/insulator. They hold the nose of the
injector in position and reduce heat transfer from the head to the
injector. If you didn't have them in there, you would have had a vacuum
leak. But fuel doesn't leak out of there.

Probably the injectors came loose from the fuel rail, as it would have
only been the o-rings holding them in, and fuel leaked from the top.
When I first fired up my engine after it had been sitting for a few years,
the o-rings had shrunk from being dry for so long... leaked like a sieve
