Default Bad injector rings

I recently put 270cc injectors in my EJ18 turbo. I would say, a few days later I had an injector ring go bad on one. I replaced that with ring from one of my 370cc injectors. Then a few days later, that same ring went bad. So I replaced that one with one from my 180cc injectors. Then tonight I had that ring go bad.

I'm starting to think that it's not the rings. What could be causing the rings to go bad the way that they are. Thanks for the help, as always.

Try using some silicone based lube when you put them in. Might be rolling them up some when you put them in.

dont use silicone lube, use what is called "rubber grease" you can find it at any auto supply store.

silicone is considered a contaminant as it will not be eaten by oil or fuel.. it is not recommended to use silicone on the fuel system, as it can get caught in an injector. Ive heard that its also not good to end up in the valves either. At any rate, rubber grease is a better lubricant for injector rings

Interesting. I had not heard that. I used it on mine and have not had any problems over 30,000 miles. Not to say i wont. I didn't put a ton on there though and the stuff i used was pretty sticky.
