Destroyed injector after cleaning ?!

[DamirGTI]

Hi Guy !

Yesterday i was cleaning my injectors on ultrasonicaly machine in one car mechanic workshop and they destroyed one injector - after cleaning i have fit injectors back , start the engine and it was running on 3 cylinders (one injector is dead , i've check that ) , now i've fit another set of my old low flow injectors and the engine works fine on all 4 cylinders ..

Please , can you explane me how is this possible to destroy injector during the cleaning process ?

Thanks !

Maybe the filter is damaged in the injector.

Blockage by tiny dirt particles usually - it's hard to damage an injector any other way.

Hi !

So what should i do next Guy ? try to clean all of them one more time , or replace this filters inside the injectors ?

How can i change/remove filters ? i see them inside the injectors , but they are really tight fitted I'm worried that i don't damage something , with what should i pull them out ? With a screwdriver or ?

I've found one article regarding ultrasonic injector cleaning ¢‚¬Å“ very interesting read :

Sorry, never done it, always regarded anything to do with injectors as a Bosch specialist job.
