injector question
need some quick advice here,
my problem is should i send my secondaries off to rc engineering to get them cleaned? i need the car running this weekend, so i would like to put it back together, but as the same time, i dont want to have to get back in the engine next week, so my question is, what should a set of injectors look like on the tip where the gas comes out, that have been working properly? the secondaries, had a little carbon built up, like that had been firing correctly, but the primaries, were just wet with gas, like that had been leaking, but they were clean, what do yall think here?
thanks in advance, my car has had an unbelieveable amount of problems.

Yeah, I seem to recall telling you to get your car exorcised...
When I pulled my injectors, they were all as you describe your secondaried to be. A bit of carbon build up on the pintle caps, clean otherwise. They came back from RC all pretty and what not. They found that all four injectors were flowing at 95%, so it really hadn't been all that necessary. More a peace of mind kind of thing. I will say that I had run two tanks treated with the Redline S2 fuel system cleaner prior to the rebuild, and the performance had DEFINATELY improved, so that may have contributed to the clean nature of my injectors. So my vote is to not worry UNLESS you have mods that require good fuel flow at high rpm, kind of like the three mod rule, where flow is increased to the point that the injectors are running 90% cycle or higher just to keep up.

spurvo, i took ur advise, man, the exorsism killed two preachers and nearly got the pope, car still didnt crank!
but thanks for your advise, and now im pretty sure my primaries were leaking, pretty much everywhere, in the engine, on the outside, everywhere, gas everywhere.
mahjik, yeah i know you are right, you pretty much always are, but i need my car going this weekend, but its looking dim, bc, i found another leak, where the fuel line from the secondary rail attaches to the primary rail, appears the o ring on the insert part of the hose that goes into the primary fuel rail is rotted, so i will have to get another one of those babies, guess i call ray crowe tomorrow, and get my package ready for rc engineering afterall.
im getting ready to try to find some information on recalls, i remember hearing about them on our cars, i dont know if mine has had the recalls, is there any way if checking? i imagine it would require the VIN, but i just dont know where to check, so i will look, but if anyone wants to let me know feel free
thanks everyone, gonna do a hose job too, long weekend, fun fun!

Wow, mine were done in three whole days! Sorry...
mcfly, the fuel recall can be determined most easily by that exact problem you found with respect to the o-ring. On the hose that connects primary to secondary, is the hose connected to the rails with hose clamps, or is it pinched into the connector like a pressure fitting (like you find for the oil cooler lines)? The recall changed the connection from a hose clamped hose that mounts to banjo joints to one that is swaged into the connector.
Either way, if the o-ring is shot, just get a whole new connecting hose from Ray. No reason to use that old dog, and if the recall wasn't done, you might consider getting an entire fuel hose upgrade kit from ray. I got one and it had all the hoses and clamps and o-rings and so on. Worth the money IMO.
Man, I feel for ya, dog! Good luck, and be careful with the fuel. Demonic posession and fuel equals melted stuff...

hey spurvo, man ur full of answers, my hose is the one that is pinched in the connector like a pressure fitting, i guess i have the recall. should i (and can i) just buy the single o ring? ive heard the hose can be pricey. and im on the reserve with the cash, who knows what else can go wrong with this beast!
also, when i pulled my primary fuel rail, there were two o rings, actually on the FUEL RAIL, i guess you might call it the injector housing, at the bottom, is this the part that the manual dont tell you about? i have heard about this earlier, but didnt really understand what was being talked about for sure.
thanks, paul

Sorry to bring back this thread, but I have a problem with my car. I assume that it's my injectors or something close to it, cause I'm running really rich. Every time I start my car it's will spit some unburn fuel out of the exhaust to the ground, and worst of all, boost shows fine on the gauge, but no power to the ground... mine mods are pretty much BPU...

Usually what happens is the exhaust will kick out some condensation that has accumulated in there on first start up. Since most of our cars run rich, it will collect some of the dirt and grime on the way out and look like wet black specs on the ground behind the exhaust.
