240SX Fuel Injector 92 KADE

[pink godzila]

Will I found out my Fuel Injector are bad and one of the injector are leaking so it also cause the knock sensor problem as while (not sure).

Where can I find some good OEM or EM 92 KADE Fuel Injector for good price? try my local nissan dealer?

Im in SoCal 626..

[SoguRacing]

the junk yard my friend.

[Kougeki]

Yup, take some cargo pants.

Any 91-98 240SX or 93-01 Altima injector works fine.

Junkyard. Make sure when you replace the injector that you lube it up (oil or gas) and rotate it as your pushing it in to prevent the oring from being "pinched"

As far as it being related to your Knock Sensor, I highly doubt it. Your knock sensor just measures pings and knocks inside the motor and retards the timing a slight bit. If your injectors leaking it shouldn't create a knock or ping, just flood the cylinder if you leave it in the ON position continously without turning it over, and make ya run a lil' rich. (andd lose a lil' fuel pressure) probally takes you a second to crank it over huh?

I would never put oil around the o-ring for a fuel injector. Petroleum causes rubber to expand. You can actually create a leak by doing this. Fuel is also no good....for the same reason.

Just use good ole' spit (really YOUR saliva) apply some to the inside of the o-rings and stick your fuel rail in. Spit works good cause it dries quickly and doesn't leave behind anything harmful.

I've been spitting on my rubber for years now, works just fine.

Oh, I suddenly feel all dirty.

Dipping the injector in oil for install is fine, they dont expand on contact....besides what do you thing fuel has in it.

No shit. The o-ring doesn't get soaked in fuel during operation. If it does then it obviously no good. The o-ring is meant to provide a seal against the fuel pressure so that no fuel leaks out. The o-rings should actually never get soaked by fuel, oil, or any other car liquid for that matter. And rubber has high absorption characteristics, what do you think those oil stabilizer and stop leak products do to your engine's seals? So soaking it in oil will definitely lead to some of it getting absorbed into the o-ring permanently.

He's looking to use something as a temporary lubricant for the injector to fit into the o-ring. Oil and fuel are hardly temporary lubricants. besides how hard is it to install your injectors without pinching the o-rings? We're talking 1-wrench difficulty here.

ive used white lithium to put my o-rings in. never really had a problem though

[Sileighty_85]

FSM calls for a "Smear of Silicone Oil" on the O-Rings
lol Smear

The o-ring does have contact with fuel regaurdless, and this is the very reason you have to always use new o-rings, if you ever compared a used o-ring to a new o-ring you can clearly see how they expanded and a used o-ring will not go back in without damaging the o-ring "buffer" thingy they sits right above the lower small o-ring. BTW been doing this method since like the year 2000 and never had a problem, also they should make a click sound as they seat in properly and you should only use your thumb to seat them home.

Trust me i've seen more than a a dozen people screw this simple job up by not lubricating the o-rings befor install and or trying to reuse there original o-rings.

[Dream240]

well......

I've ALWAYS reused my O-rings on all my 240s since my first fuel rail job (oh about 7 years ago) and I've never lubricated them with fuel/oil, pinched the rubber, ruined the seal, or otherwise damaged the fuel delivery system. And I've never had a fuel leak, low pressure, or thrown an error code due to faulty o-rings.

So what now...?

To each his own I guess.

EDIT:

Unisa Jecs: I guess you and me just love to disagree.... lol :)

[emayearecee]

I sprayed mine with WD-40 and they work for like 5 minutes, then go bad. LOL. I guess the WD-40 fried it somehow.
Oops, I didnt know that

So I finally got smart and put a minimal amount of Di-electric grease on the o-ring and screwed a new one in. Has been working just fine for the past two months or so.

More IMPORTANTLY THOUGH. I have one you can have for $30 PM me

[pink godzila]

I just got a deal for all 4 new OEM injector for 150$ pick-up tomorrow

That's a great deal considering the last time I checked, they went for about 100 a piece.

Good luck.

Good job, you succeded at being ghetto.

I mean you can get O-rings for like $5.

Do things the right way.

People are just like you with FC's and next thing you know their shit is on fire.

Just shoot the O-ring with Silicone spray.

DONE.
