Welding to injector - 3.2mm Elga 312's 120amp DC (be careful of the self releasing slag).
Then I have three options:
1. Hollow ram - with threaded sacrificial adapters I turn up on lathe and then weld or thread to injector. Plus huge plate with M12/M14 threaded holes everywhere - to pack it out where I can get it on top of engine rocker cover (was too mean to buy Pilcher kit so made my own)
2. Monster homemade slide hammer - with threaded sacrificial adapters I turn up on lathe and then weld or thread to injector.
3. Big lump of metal with an air chisel bit welded under it - with threaded sacrificial adapters I turn up on lathe and then weld or thread to injector. Connect air chisel with defeated throttle and ball valve on inlet - leave for hours rattling away.
Option 1. Works mostly but breaks lots of tooling and I have snapped injectors in half and left half down a hole. Then you are in for fight - drilling and tapping.
Option 2. Works sometimes but it makes you sweat - and is hard work.
Option 3. Is more sucessfull than you would imagine - but you gotta be patient. Plus you gotta be about while you are doing it - supervising it.
Soaking them up for a day or two has to be the plan. I have tried everything from WD40 - citric acid - Acetone/ATF - numurous special tins of "injector release agent". Nothing seems to be any better than anything else.
