well here it goes, got this sprinter here for check engine light and found three glow plug codes, removed the bad glow plugs, tested them and they are in fact nonoperational. customer actually asked for all six to be replaced, wow, ok. well now i have this problem, got five out no problem, the last one (of course) broke at the threads, other than buying a $400 tool and having to wait on shipping, does anyone have a real world repair for this without drilling the head? thanks guys.
