fuel inector seals
Hey guys,
Does anyone know what the purpose of the larger (top) fuel injector seal? It's held in place w/ one of those snap rings It doesn't seem to seal anything at all? The lower seal makes sense to me because it seals the injector as it enter the engine.

Hey a fellow Canuck with a GTV6 eh ! Greg the upper ring serves as the contact point for the "oval" metal rings that push the injectors down against the manifold to create an airtight seal.These rings are compressed by 2 bolts which attach to the engine - but I guess you already knew that if you took them out.

Greg I have both a brand new and a used lower inj.seal in front of me.The brand new one is in fact not tapered and I have them in my car.They work fine.Looking at the used seal I would say that the contour is the result of the seal having been pressed down into the hot engine and taking the shape of the injector hole over time.

Greg replacing the injector hoses is a wise thing to do.Over the last 4 years I've replaced everything made of rubber that carries fuel.I replaced all my injectors with those sold by Greg Gordon.I figured after 20 years they were getting tired.My understanding is that other than blockages which can be dealt with by ultrasonic cleaning, the classic failure mode for older injectors is leaking of the internal seals.This can only be addressed by replacing the injector.

Greg here's Greg Gordon's e-mail address.He's the ultimate GTV6 Guru and can answer any questions you have related to injectors etc.His injectors are a modern direct replacement for the GTV6 injectors and many on this site are using them.

He also has built a great website that covers most the ins and outs of these vehicles.I strongly recommend that you spend some time there. ( site appears to be down at the moment but I presume it will be back up soon ?)
