leaky injectors

Hi guys...

ok, so after getting a confusing picture from nissan about which way the rubbers go onto the injectors, I eventually just went with the same way they were when I pulled them out...

According to the picture from nissan, its just the o-ring that fits on the rail side, then the spacer rubber and that flat washer type rubber fit on the other side where the injector goes into the manifold. The way they came out, had the o-ring then the spacer rubber, and just that flat washer rubber on the manifold side... replaced it this way. Anyone, please feel free to clear this up...

After replacing it, I see injector number 3 is the culprit... its a bit wet around the top, on that plastic part where the connector plug goes in... there are 2 small holes on that plastic thing, and the best way I can describe it is like the water pump that has those 2 holes on the side, and its starts the drip water out... is this repairable at all, or is it just eaasier to replace this one injector.

Thanks.

If you are sure the petrol is leaking out of the holes then the injector is frot.....you can't repair that, but be very sure, the o- ring is the culpret 99% of the time.....

Mo did you grease up the o-rings? Sometimes they go a bit skew as you insert them again etc.

VC you mentioned something about the Rotary guys injectors fitting in our cars? And that most of them upgrade anyways so they should have some laying around??

yeah, I did...
if it was leaking from teh o-ring, I think it would be pouring the petrol out...

this seems like its coming from those 2 holes... if I wipe it, it stays clear for a while, then after a bit starts to look a bit wet again...

Not neccsaraly...I've had the o-ring leak from a few drops to a stream poring out.....sometimes even different when you install it, take it out and installing the same again...different leaks....

yeah you guys need to be very very careful when installing the or-rings.

you need to get even pressure all around the o-ring.
you need to lube it up with something good - like CASTROL red rubber grease.

god this sounds dodgy!!! 😮 😮 😮

and yes G - the mazda rotary ones fit. they are 550cc's too, so its an upgrade for us smallfries!!! and there are always some extra lying around. i think i noticed some on offer in junkmail this week, at R200 a pop. not bad for a 550cc injector hey!

At R200 a pop it's cheap man.

the dude was selling a set of 4 too!
nice upgrade if you have managment.
