injector cracks in bore?
I am going to start disassembling my injector setup so that when my stuff gets here I'm ready to go, I have heard of injectors snapping in half when pulling them out, if this happens to me what should I do in that situation, also I have a round wire brush that I figured I would use to clean the bores, if the carbon falls into the motor would that be really bad?

It is not that the injectors are cracking in half, the lower part is unscrewing in the head.
As you look at that picture, see the line around the injector to the left of the threads?
That is where you take the injector apart.
Seems like 1 in 500 unscrew there as you try to pull them out.
If that happens don't panic.
My first action after that happened would be a good dose of PB Blaster around the lower portion.
Then I would grind the threads off the upper section and screw it back into the lower section.
Then turning clockwise while pulling up on the injector body till it comes out.
A shop vac held close to the brush while brushing out the carbon should pick up most of it up.
I used a piece of 1/2" copper pipe and a garbage bag adapter in the end of my shop vac hose to make a crevice tool so the vac would be very concentrated near the brush when I did mine.
Worked like a champ.

Thanks Dave!
This is the kind of stuff I print off and pin in a folder on the wall in my garage, so I don't start a job without knowing how it could go wrong and what to do when it does!
This is why I love this forum...
