Rb26dett Stock Injectors Leaking

[R33-RB26DETT]

Hi Guys,

I am thinking off pulling out my leaking GTR Injectors and replacing the O Rings myself.

Only issue is that i want to make sure that the actual housing of the injectors isn't cracked.

After I have pulled out all 6 of them how easy would it be to see if one of them is cracked?

Would they be visible cracks or would they be too small to see with the naked eye?

Not on mine, just look around the injectors while the engine is running, was easy to see the fuel on the body, and the stench.

The injector bodies dont crack. Its the o-rings that cause the leak or the pintle is not seating properly. Need to get them flowed professionally and fit new o-rings. That will then fix them.

ahh no.

The o'rings were fine on mine. Fuel was leaking out of the body.

Where the Yellow top meets the black body.

Cant see the crack/split/hole whatever it is but with the engine running you sure as hell could see the fuel seeping out everywhere and it definately was not from the o'rings as they were dry as.

Another good way is to look at the condition of the injector body. Generally if they are all kinda dirty and dusty except for one or two then those cleaner ones will be leaking. Its the fuel leaking out that washes them clean.

^ this is right, even had them tested and confirmed as that was the problem.

Ok. You might need to replace the leaking one then. Plenty of s/h ones for sale. G/L dude.

Hey Guys

Got a 32gtr, same problem about 4 of the injectors are leaking. I replaced the o rings but that didnt fix it. I was told that the injectors can sometimes crack inside hence them leaking.

The engine is stock and im happy to keep it that way for now. I also was told that if i go for higher cc i will need a remap. ?? I cannot find replacement injectors which are the same as stock, apart from nissan who want $260 each !!

Not sure what to do, i know i could just get them cleaned and tested, but why waste the money when i could just buy a new set and be done with it.

Any suggestions please ?
