Sad Fuel Injector
I have a 1997 toyota corolla, one of the injector is leaking, can it be the 0-ring, it has a crack in it. Do I need to replace the one leaking. How about the rest of the injectors. Do I need to replace the o-rings also. It leaks when car start up. What suggestion do I need to doSad

RE: Fuel Injector
If it is the o ring at the base where it mounts to manifold yes it can be replaced. You can get them at most parts houses .I would replace all while you have the rail off.

No, it is the o ring at the injector where it mounts to the fuel rail. Does this stop the leaking.

RE: Fuel Injector
The dealer should sell the O ring you need.  If it goes on top of the injector going into the fuel rail.  You need to lubricate the new one when it is being installed to keep from damaging it.  Good luck.

Sorry for jumping retired. Smile

Being way2old is why I need help from younger minds.

RE: Fuel Injector
Im not trying to be funny, but : If that is where its leaking from ,yes . If its the body of the injector then no. You said the o ring was split . so i would think it worth the price of an o ring to find out.
