Had my car over at local shop for small stuff and he noticed a small vac leak at one of my injectors. It is the very front left one when looking at motor. He could hear it. Sprayed at the site and the car ran different. New injectors. O-ring or something else ? Pretty easy to take that one out to put new ring on ? Looks like I might only need to remove the intake cover and the air filter cover. What Cyl is that anyway ? Not throwing any lean codes and car runs really good. He thought I could be loosing some boost with this.

Replace the o ring and you will be fine.
Since you have the 550cc injectors did you use the oem clips to secure it to the fuel rail?

I am not sure what clips were used. I had someone else (MB tech) do it when he did the TB and other stuff. Is it pretty easy to replace the injector O-ring ? Looks like its just a number of TQ bolts to get at it before I could pop it out. Any special tools required or anything else I should be aware of before doing it ? Would one of my old injector o-rings work ? I wonder if it got dirt in it or there wasnt enough lube used.

Is it dangerous to drive like this ? I have no idea how long it was leaking.

if you have the red 550 cc injectors i am almost 99% sure the retaining the injector to the fuel rail were not used and that caused the injector to move.

Pretty sure those are the ones I got. So does that mean all of them could do this ? I need to call the guy that put them on and see what he says I guess.
