Hi one of my fuel injectors is leaking

it looks like it's coming from around top of it, it's only a very small leak looks damp around the injector

obviously my first guess is to replace the injector... is there anything else it could/would be to do with the fuel rail or anything?

Thanks

Might just be the top injector o-ring is gone

Yeah, try swapping it, and the other 5 while your at it of course. Its pretty easy. My DIY might help (for GTR but i think the 20s are similar) HERE. I got the seals from Nissan but any injection place should have them.

yeah that actually sounds more likely than a cracked injector..

are the seals on the bottom that go between the head and injector the same size as the top ones?

i just ordered 6 for the bottom from nissan and he said there is a O ring for the bottom and 'resistor' or something to that tune for the top and bottom of the injector or something

didn't say anything about an O ring on top

Edited by mystery_kid

On the GTR the seals at the bottom are not o-rings (but they might call them o rings), its almost a square cross section. They're not that critical. On the top of the injector is a rubber spacer and an o ring. Again the spacer is not that critical, but the o-ring is essential as it makes the seal. I probably have the part number at home...

Also injectors can leak (mine did). I replaced the seals first as i couldnt tell where the leak was from. Didnt fix it so I replaced the injectors.

    • Jax Tyres Smithfeild Ive gone there a few time, well for tyres. on my 3rd visit I spoke to the dude and told how i just got slugged for rotors, brakes ect. His reply was golden; have you read whats on the front of the building. Never forgot it.       before picture, good friend got all these goodies installed.  Well time to study, servicing, maintenance all before this weekend driving lesson.  
    • Hello, first of, I’ve looked at many threads on this code but none have helped me, if you know one that will help me feel free to post a link.   Now to my problem. Recently I was driving and noticed the check engine light came on. I went home and did the test to see what code it gave. I got the 21 code but everything seems fine with the car, no misfire, idle is good, acceleration is the same as when I bought it. I mean no signs of obvious failure. If no misfire is happening I can rule out the coil packs right? Which is about 98% of posts saying it is. If anyone has had this happen and found the issues let me know please. No other lights are on.   The car WAS due for an oil change. I since then changed it so idk if that triggers code 21. Either way it hasn’t turned off.
    • Your both right, it may hold a bit longer then.  Soon I need to change the synchros, should I fit the billet plate while I'm at it? Or just a waste of money?
    • Some of the east coast US Stagea got together this past weekend at Lime Rock Park in CT for Grid Life Circuit Legends. This is probably my favorite pic of the shoot with @Morgan.Mundahl on IG. Hope we get more stags out next year! i think I spotted 5 other than my own at the event.
