I have been carefully working this last injector screw. Tighten a fraction, then loosen a fraction, used penatrating oil, etc etc. Been on this for a week. Finally most of the grip within the screw head is gone, so I can't even grip with the phillips screwdriver. This is in a tight spot. Any suggestions on removing this? I have a spare car with an intact fuel rail, injectors, and screws, etc, so if I have to break this injector I will, but I want to use that as a last resort!!

Thanks to any and all that can help.

No skin off my teeth

Super Glue on the other hand I already tried that on something else

(out of desperation) and coming to think of it, it didn't work :bandit:

~Z~

Well, for the heck of it I tried the super glue trick, waste of time that was :stupid:

So My cordless drill is worthless, battery is kaput, so tomorrow I am off to the Sears or Northern Tool to pickup a new drill AND that screw bit set. I will let ya'll know how the set works for me. I noticed the Craftsman set is a 3pc for $20 and the other set is only 2pc, I will see what Northern Tool has and let you all know what happens. Thanks again for all this input! :beard:

I think the only glue that would work would be a quick set 2 part epoxy. mostly because of how fast it dries, and how hard it dries.

but then you have the hassle of trying to separate the screwdriver from the screw.

If you are going to Sears anyhow, don't discount the advise you got from Kenny P. and also get a bottle of the Craftsman Grip Doctor. Or do like I do and use some coarse valve lapping compound on the tip of the screw driver. Same principal is used, giving you a much better grip on the screw. It could be too late this time, but a little finese should be exercised when you come across a problem screw such as this. Take the extra time to match the screw up with the proper sized screwdriver. I can tell before a screwdriver slips that it is about to. That's when I stop before damaging the screw and assess the situation. I'll use a "screw out" or cut a new slot as a last resort, but the Grip Doctor is a great tip also.

Vise Grips saved the day! Well, just now, found my smallest pair of vise grips, removed the wire connector from the injector, but the only space to squeeze into was between the intake and fuel rail. Could turn about a 16th of a turn (MAYBE that much, maybe less). Attached is a picture of what is left of the screw, down on the threads there looks to be locktite though, can't imagine that was needed unless PO had to retighten the screw and wanted to use it. Thanks for all your help guys! I WILL still be picking that set up this week, I am sure I will need something like that in the near future while removing these 30yr old screws elseware on the car.

Thanks man, I will grab some of that stuff while I am there too. :pirate:
