Leaking Injectors - How to Fix?

[aN4rk1]

Ok guys,
I did a once over of my car yesterday and found my injectors were leaking. I want to fix them, I will need new o-rings right? Is there a tut on how to do this? i tried googling, no go

1. get o-rings from nissan dealership. they were cheap last time i did it.
2. take out metal clip on each injector. careful not to drop down below! use some needle nose pliers.
3. take out 2 bolts holding fuel rail.
4. pop the injectors out of the head and jimmy past the fuel rail.
5. slide the new o-rings on.
6. put everything back.

done in under an hour.

Injector O-rings 16618-78A00, 16635-78A00, 16636-V5000

Spout, middle (rail), tip (ITB body)... not sure of the order though. They're off a KA24E (89-90).

You could of used the search function... I had made a post about it back in june 2010. One of my first posts actually. BTW, your hats may (probably) are leaking. Better pressure test the injectors too.

Make sure to blow the dirt out around the injectors so it doesnt drop I to the ignition chamber. When your putting them in put the injectors into the phenum then line up the injectors. Don't push them in all the way into the rail just tighten the two bolts bit by bit to let them go in themselves. If that makes sense.

Sometimes the injector itself is just crap. You can try getting the rings but if it still leaks. Buy different injectors. Used stockers can be had for $20 a piece from the right source.

Missed step 2. Start car and pull fuel pump fuse! Lakes life easier.
