OK I already know I'm an idot...
When I was replacing my injectors the nozzle tip along with the body got stuck inside. I cranked the engine and got the nozzle out. But the body is still down there. I tried the pulley idea didn't work so I tried prying on the side walls of the body and didn't get it. Should not have done that last part oops. What's the next step? Thanks.
What you do is take the injector body, grind the big threads off of it(it's shot at this point anyway). Then, thread the body into the cap down in the injector bore(which should be possible now that there's no big threads on it). Then, just pull and twist until it comes out.
Get a drill bit about the size of the injector body, just slightly smaller. Stick it down in there and whack the back of it with a hammer a few times, hopefully with it cutting a groove into the injector body. You can then put a vice-grip on it and try to "thread" the drillbit into the body. With any luck, the body will break free of all the carbon and crud, at which point you can pull up on the drill as you twist it and get it out.
I'm a little worried for you. I remember my stuck injector and it was a PITA. Days of soaking the carbon helped, but in the end, I was turning that injector with a pry bar 1/12th at a time with all my force. I don't think a vice grips will do it, even if seafoam was dripped on it for a week.
Does anyone know how thick the metal is on that part of the injector? If it's somewhat thin, could he carefully pound in a centerpunch where the crud is? Then it will deform the injector casing to be a "C" shape? Or is it too thick and it wouldn't likely deform?
At least if he could deform it, then he could potentially wedge a large screwdriver or piece of steel in there to turn it with a prybar.
IDK how to help much. My stuck injector was such a pain to remove. I'd say if you can find a metal centerpunch that could warp the side of the injector housing, that could be a decent way to separate the injector casing from the sleeve of crud, rather than risk using a drill which might put metal shavings down in the cylinder.
OOOOOOR.... Maybe you get a high quality dental pick. Straight. Then chisel away at the wall of crud. It'd be time consuming, and you'd need to make a shopvac hose attachment with a small suction hose to help keep the debris from falling into the chamber, but that could help to break up the carbon. Seafoam + pick + suck, and repeat. Better than pulling the head.
