Welcome to the Diesel Forums! Sorry, I don't have a clue. But have you tried letting any penetrant soak for a while? We use to use "oil of wintergreen" on steam turbines.

Hello and welcome to the forum.


Mods please cut and paste this info below and make a new thread please.

You problem is common. I t will take this Tool to get it out. Most of the guys that use it don't like it because puts alot of sideways force on the injector.http://www.usatoolwarehouse.com/usatoolwarehouse/OTC-J-44639.html

This is from another member and a forum that has done this method.

Edited
2500HeavyDuty: "If you have to use a small pry bar to pop them out from the top using the bottom of the high pressure supply line on the injector as a pry point and the head bolt as your fulcrum. They should pop right out pretty easily. Make sure to remove the copper washer from the bottom of the cup if it doesn't come out with the injector. be sure not to lose the steel button that rests under the bracket that holds down the injector, it usually stays in place, but make sure it doesn't go anywhere."

I hope this will help you. The cup might come out with the injector, this is fine. Make sure all of the O-rings are replaced, and that you have the coolant out and your good. I hope you didn't use to much heat? Aluminum heads don't like that.
I hope you have the heads still on for the removal of injectors. It makes it allot easier, then having them off. You might have to have the heads checked after this.

Thanks guys.. I appreciate all the info. I am still struggling with the injector. The injector is seized around the collor of the injectore where it goes thru the valve cover. I'm confident the heads will be fine but will have them checked for sure. I have soaked it for 2 nights in a good quality fluid film and began prying on it last night to the point I broke the lock off the injector. I going to keep repeating the process till it frees up. Last resort will be to remove head and press injector out from bottom. Likely end up losing the injector in the battle.

If the heads are off take them to an "aluminum safe" solvent tank, and let them soak for a bit and then try prying on them again.

aluminum safe: means nothing but aluminum has been in the solvent tank.
