Stuck #3 Cylinder Injector Retaining Nut
Vehicle-2000 JettaTDI 217K

Problem- I cannot get the #3 Injector retaining nut out. I did unthread thread the injector body from the retaining nut and have made multiple attempts to loosen the carbon buildup between the nut and engine block with PBR Blasting Lubricant, CRC Carb CLeaner, and CRC Freeze Off. After every application of the formentioned chemicals I would then rethread the body back in (all internal parts removed including nozzle) and attempt to pull it out with all the force I could get on a pair of ViseGrips. After 2 hours of attempts to yank it out and damaging the injector body and sensor wire I gave up.
Today I tried the Slide Hammer method; mine having even more weight than the one Metalnerd sells; threaded on to the injector body and still not coming out; not even the slightest budge.
Has anyone threaded something into the machine threads of the retaining nut and had results? Any other ideas/solutions would be much appreciated.
