Fixing Leaky Injectors??

[JBNR32]

So my gtr has leaking injectors, a few pretty badly. The nissan dealership that is checking out my car has told me I require new ones? I thought I would beable to change the o rings once I remove the injector is this true? if so anyone have the partnumber and or other items I will need to replace. Thanks in advance for any information provided.

"Leaking injectors" doesn't usually mean leaking outside the engine, it usually means leaking fuel into the engine. This is not a good thing, as you can get hydraulic lock if too much flows lays in the engine (say overnight). When you turn the starter motor next morning you can easily bend the conrods (petrol does not compress). Changing O'rings will do nothing for that. It is easy to confirm, just stick the injectors on a flow bench and see how much fue lcomes out when they are closed.

The normal course of action is to get the injectors cleaned as most time the pintle is kept open by a build up of gunk from the petrol used. A good overnight ultrasonic clean will generally fix this. Then they can be retested on the flow bench to make sure they are not leaking. Cost about $20-30 per injector.

Hope that helps

I've had leaking injectors in mine and new O Rings and seals didn't fix the job. they were leaking out of the 'body' of the injector. You could physically see the fuel seeping out of the injector. I ended up getting a set of late model GTR injectors from a wrecker and with all new seals (there's 3 for each injector and total cost is about $170) from nissan and all is good.

Dont get new RB26 injectors from nissan because when I was loking at doing that they wanted $270 each!! For that price you can get a set of bigger SARDS or NISMO's etc.

Good luck
