Thread: injector issue

Did a coolant flush on my 05 n/a this morning. I hear a hissing noise in the process. Looking around I notice the noise is coming from number 2 injector. I can press down on the injector and it goes away. So I spit a little bit on it to see if air is coming out or sucking in. Well the spit immediaytely sucked into the cylinder. No gas coming out injector. is goin on?

You need a new injector O-ring, I think you can buy a set of 6 for like $4.

I kinda figured that. But sucking in air? I've had o rings go out before and they always leak fuel.

N/a injectors are in the Intake manifold, Hence the vac leak

If the o ring was bad on top it would leak gas on the bottom it will create a vacuum leak.

Ok that makes sense... I didn't even notice that. Was more focused on the injector itself. Is there a part number for the o rings that u know of?
