Injection Objection (Isn't that pretty?)

[weirdstyles.net]

I pulled my innjectors, rail, FPR and, Valve Cover today.

The rail is fine, injectors are old and worn but usable, FPR's lower hose was ripped off and the v.cover had a break in her.

So I replaced the v.cover, used 10 ft-lb to start, check back in a week. That went splendid.

Replaced the FPR lower hose, and cleaned out the bottom opening. Put new o-rings on the injectors, fit them back in the rail. I put them all in the same way, with a light twisting to make sure the o-rings didnt bunch or hold. Put her all back together, and the mother flucking #2 injector is spraying like a broken nitrous hose...

Now heres my questions;

#1 what is the gromet between the injector and the injector "port" called?

#2, Are the injecter o-rings a little loose when you put them on or, should they be very tight and fitting on the injector?

You see, the Advanced Auto Parts ***(ociate) assured me these were correct. I compared them to the old o-rings and they appeared a bit larger but I trusted him anyway.

So now I have to waste more time tommarow to pull the FRP back off, then the lines attached to the fuel rail, then the rail itself to find out what the hell went wrong. Being that the injector never sprayed before, it probably wouldnt be the gromet correct? Then it should be the o-ring on the injector. BUT none of the other injectors are spraying like the #2 and I mimiced the process with each o-ring on all of the injectors. I couldnt really get a close look of where it was spraying (top/bottom), I was kinda worried about the whole spraying of the gasoline on my engine.

So any idea of what the hell went wrong?

Hopefully, Rob.

Rob, since you practally duplicated the process on the other three and they are tight..you may have a bad O ring. I can't imagine number 2 being any different from the rest of the injectors unless some grime or something kept it from seating properly.

One thing that has worked for me is to lube the oil ring a shade so it seats properly..(like you do on the oil filter seal) Some crud may have gotten somewhere you may not have noticed...or your rail is slightly bent...or you got a bad O ring.

You can make them contract some by sticking them in the freezer for about 20 mins as well.

I had a bowl-plate gasket that was simply too big to fit the seal on a Mazda carb once..the freezer trick made it work every time I had to adjust the float.

Another post from Bill. Thanks for the post, after I drop the lady off at some school function, Im going to get started pulling everything apart. I wish I had the money for some injectors, as I know they need some TLC. What I plan to do is, considering the R&R of the rail is like 15 minutes top, I will drop the lady off, get home and pull the injectors and rail, put the rings in the freezer. Go back to Rowan to pick her up. Come back and put **** together.


Is there any cleaning solution I can leave the injectors in over a short period of time to clear em out?

'nother question. What happens if my FRP's lower hose (from the very bottom) is dosconeccted?
