Leaky Injector. How do I...

Could someone help explain what is involved in replacing the o-rings on the fuel injectors?

im sure if you were to get a manuel, haynes or the likes, it would describe it in detail with pictures, and it would be a good investment.

I bought the Haynes manual. It gave some description, but not very detailed. Just enough to figure some of it out on my own. Getting the injectors to pop out of their seats and out of the fuel rail was not easy at all. Putting them back in was significantly more difficult. Haynes offered no insight on technique, do's or don'ts - just 'remove,' and 'install.'

In the end, the injector body was leaking not the seal - so I replaced the injector and refreshed all the seals. One o-ring sheared when the fuel rail cap finally seated fully -with the gentle help of a small 2x4 block and a 16 oz framing hammer. By the time I reached that point in the project, it was either a hammer or a match...

It's not leaking now so I'm not going to disturb it again. I'll just keep an eye on it in the future. The right side of the intake manifold sure is clean now...
