| my brother has a 96 sc series 2 engine. his o rings are leaking on his injectors. after going to oriely's to get the o-rings, i noticed that he has 3 o-rings per injector. the part store only gave me 2. it appears the 3 o-ring sits at the bottom of the injector right below the lower o-ring. my question is has anyone replaced the orings on their injectors with just the 2 piece set from parts store, and if so did they leak? help me, cause im tired of giving this dude rides to work. gas is high as hell. | |

| i've got a 98 series 2 and it only requires one o-ring on the bottom of injector.
I would think an additional o-ring in that area would actually cause a problem.
When you order an o-ring kit from GM it only comes with 12 o-rings total, 2 per injector. | |

| 2 rings per injector, one per end. Putting 2 on one end probably helped it leak, imo. _________________ '05 GTO 6.0L • 6-spd • 95k miles • 0-60: 4.8s • 16.9 avg MPG • Nelson Ledges Lap: 1:26'95 Celica GT 2.2L • 5-spd • 165k miles • 0-60: yes'98 SC Riviera • 281k miles • 298 HP/370 TQ • 0-60: 5.79s • ET: 13.97 @ 99.28 • 4087 lb • 20.1 avg MPG • Nelson Ledges Lap: 1:30

 somebody pulled the injectors out and didn't notice the o-ring didn't come with it. Plus there is a lower retainer that's probably broken off, may be sitting below that o-ring too. | |

| Use a small pick with a hook on the end to feel down in the injector ports and remove any o-rings or broken retainers before installing new o-rings and injectors.
Broken retainers are not uncommon and the injector is still usable without the lower o-ring retainer. | |
