Fixing Flood Problem- Taking Injectors out
 

Ok, so i tried searching for "Flooding" and things like that but there are just so many flooding issues I couldn't relaly find what i needed?


anyways tommorow i'm going to be taking out the injectors, i've done this before on my integra but not on my rx7. i know i have to take off the intake manifold and things like that but i'm curious as to how hard the actual job is?

my car cant sit for more than 6 hours before it floods, so i figure its leaky injectors. anyhow, i'm looking for a quick fix without really replacing anything like o rings or sending the inecjtors to a shop. would dipping the injectors in lucas injector cleaner work?

i'm really cheap right now because i'm saving up for my TII motor.

Removing he UIM and all that jazz is pretty easy as is getting the injectors out. Don't drop any bolts down any holes they don't belong in and you'll be fine :)

thanks for the quick reply, as for the dipping lucas injector cleaner, would that create a proper seal so they dont leak? or should i just head over to mazda and try to get new rings?

get new rings man! I have done what you are getting ready to do and i have also had many buds do what you wanna do. Please for the love of god do not get lucas injector cleaner! all that shit is, is a high octane boost that makes your car run good for a full tank of gas! There is no such thing as injector cleaner!!!

i didnt mean to put it in my gas tank, i meant to drench the injectors in it?

how much are o rings?

not much just hard to find seperate i would call mazdatrix or racing beat on this matter

Man... I don't know if there's a lot you can do without getting the injectors cleaned. I doubt that dipping the injectors will do anything productive.

Save up $60 and send them here: http://witchhunter.com/. At least check out there sight, it's pretty informative. I've actually seen the facility and how the testing takes place; it's pretty cool.

I'm with erikseven on this one..if you are removing the injectors , get them done right(by a pro)..get them cleaned or replace them..you'll save yourself the time of having to get them out again ..because you are "quick fixing" (we all know where that leads)....It's relatively cheap..Eat some rahmen for a week and you'll be pattin yourself on the back for doin things right..(the first time not after you have to take them out..Again)..my $.02

I had thought that the injectors leaked from it's seals? Or does it leak THRU the injectors itself? I plan on getting a TII motor within 2-4 weeks. I mean i not poor or anything, just that i dont wanna go thru the hassle of sending them, and recieving and then putting them back in when i could have a new motor by then?

anyone?

Injectors can leak internally, which floods the intake.

The O-ring seals can leak externally, which can start a fire.

Anytime you pull the injectors you should have some spare O-rings handy.
There is not much squeeze on them to make the seal, and they often get scratched during removal.
Make sure the fuel rail sockets a perfectly clean & smooth.
Sometimes a piece of the old O-ring can bond to the socket.
Oil the new O-rings for assembly.

Always pressure check the system before bottoning it up.

think of it this way.

The Pressurized fuel system stays under pressure when you turn your key off. That pressure finds the weak seal in one of your injectors and allows gas to seap into the intake.

The leak is inside your Injectors, not the seals that you see when you pull out the injectores

Oversimplified.

thank you. exactly what i was looking for

im gona try depressurizing the fuel system before i shut off the car (at night). pulling the fuel pump relay while engine is running. would this work for just a few more weeks? i know its a ghetto band aid.

^^according to Mazdatrix (which I trust) Yes. They try to sell a return valve that does the same thing. It allows the pressure to be relieved into the return fuel line. What you are going to do should be the same thing because..........just like the FSM says, before you crack the fuel lines, remove the Relay and allow the motor to die..............accomplishes the same thing.

Mark the position of the vaccum lines as you remove them. You may have to also replace vacuum lines, oil injector lines, and the pulsation damper. Lines are brittle and break easily and pulsation damper causes fires. Look at some of the other threads.
