Oil Injectors rebuild! (with video)
Hello everyone. I'm from the Greek club and found a way to repair vacuum leaking oil injectors. It's a guaranteed process unless the one way valve inside is warped.... I have posted a video on youtube repairing all 4 of them and wanted to share with you also!

Yes, just ultrasonic cleans them perfectly, but in my case the o-ring on top was totaly dry, hard like a nylon washer, loosing all of its sealing properties and had oil and combustion derbis blowby around the valve's plastic mounting perimeter(that gray plastic) and created an additional path for vacuum leak.
That might be why you are having 20% of the repairs failure or there might be a warped reed valve (that red coloured rubber). I once found one a bit warped, repaired it anyway and it could hold vaccum on an instant pull with the syringe but it would slowly loose it (5 sec gradually) not immediately..
From now on since I used gasket sealer it should be ok and I'll just maintain them next time only in the ultrasonic

I found the same thing to be true. It is the o ring hardening that brings on the vacuum leak, not the actual valve.
