injectors leaking?

[br2819]

hey you guys i have a 90 240 coupe and the fuel injectors seem to be leaking. is there any way to fix this without buying new injectors. my friend thinks you can buy injector o-rings but i can't seem to find them anywhere.

NAPA and autozone both carry injector seals, as well as any nissan dealer

i went to an autozone but they told me they don't have anything like that.

Such a common item, maybe the guy was new. Go to a dealership or call one of our sponsors. They shouldn't be more than $2 or 3 each. 2 seals/injector I think, may as well replace both on all 4.

Question, can actual injectors leak, or is it always the seals? How do you determine which it is?

[DAEDALUS]

It's possible for injectors to leak but most often the seals go bad. When injectors go bad they usually go open loop and don't do anything.

You have to pull the fuel rail and pressurize it with gas to see if it's the seal or the injector.
