    You won't need a special tool. You use the provided cap to slide a new o-ring into the groove on the injector tips. When you buy new injectors this cap is there on the injector tips. You have to make sure that if you take the cap off you have to get it installed very shortly after as the seal will expand.

    Thanks,

    I do know about the time limit upon removing the injector cap with new injectors.

    I had no idea you could replace the rubber o-ring on an old injector by simply pushing it on with the cap.

    Have I got that right?

    BMW has a special tool and procedure to remove the old o-ring and stretch on a replacement without touching the injector tip. Guess I'm kinda surprised you can just push it on with the cap?

    I am having the same issues as you and changed alot of the same stuff. Tried reading through your threads on this but I may be missing one since the topic jumped across several of your threads since you dealt with it for so long. I saw you replaced the cam bearing ledges but the issue still came back. Did you ever get it figured out without having to turn off misfire detection in the flash?

    I've had multiple cylinder misfires only high boost/load high rpm. Several different codes related to misfires to different cylinders at different time but basically only cylinder misfire codes and sometime Vanos solenoid code, replaced all coils and plugs and vanos solenoids. May have leaky injector as I have rough cold starts on E85, will check tomorrow morning if gas on plugs. Now only get different cylinder misfire codes but does not seem to be consistent on a cylinder or bank even.

    What does hdp stand for?
    logged LPFP and HPFP and both are perfect
    using stock plugs, less than 5k miles, just pulled them all and they look perfect and non smell like gas. Running 100% E85 and meth.
