I may have a partially blocked injector on my 1989 Spider S3. Does anyone have stories or reports about having injectors reconditioned? I've read comments about them not really being able to be properly reconditioned due to being sealed. Comments welcome.

I know that new injectors will be expensive if I mention the word 'Alfa'. Surely the same injector must be used on other cars. Does anyone know? I'm quite capable of fitting them and even adapting the pipe if necessary. Please bear in mind that I am in the UK, and many S3 cars over here, if of European import, are fitted with carburettors. Consequently, injectors are not particularly common. It would seem that it is the cars imported from the USA that have the injected engines.

If anyone thinks they may know but wants to see a picture, please let me know.

Thanks for the quick responses so far. With the Bosch part number above, I have found (in case anyone is interested), that it has a flow rate of 191cc at 3 Bar pressure and has 2.4 Ohm resistance. More can be found on the injector specifications at the following -

If you want to try cleaning the injectors, consider an outfit like Cruzin Performance (there are other companies offering similar service). True - the injectors cannot be rebuilt as the internal bits are inaccessable. Cruizin Performance replaces the inlet screen & external seals, cleans them with an ultrasonic solvent treatment and does a before & after flow test.

If an injector is truely dead then Greg likely has your best deal for new ones.

Darren's picture of a fine Bosch injector will not fit. it will not mount like the OE's.

The correct Bosch # is 280-150-128

BTW Cruzin also replaces the pintle cap and gives actual measurements of static flow as well as pulsed flow and spray pattern and leak.

Best regards,

Looks like what I remember the injectors were like in our '84 Spider. The mounting flange is slide on (from the bottom) then a rubber ring and both are secured with a C-clip (called 'seeger ring' in the sketch below). The rubber ring & C-clip fits into the narrower part of the injector body. The flange pushes down on the C-clip/rubber ring to hold the injector in place.

Except the injectors in our cars cannot be rebuilt. They can be cleaned & the inlet screens & external seals replaced but the internals cannot be accessed for any sort of 'rebuilding'. And outfits like Cruizin Performance does the cleaning/seal replacement for $16/injector.

OK, but if you end up with one that is toast and can't be made better you can get a non-rebuilt one for 42 dollars instead of 200-300 dollars.

$16 is still better

To show what the lost/missing/NLA pic in my post above was and to give direct comparision to the p# Elio mentions.
(I'm guessing 2cc difference in flow isn't going to be a travesty making either suitable for use)

Both injectors are physically the same size, difference shown is a result of how they were photographed.
