well the drilling and tapping went sort of ok i started by drilling 2.5mm first and working my way up i tried to use a left handed drill bit to hopefully twist what was left out but no joy so i then tried a bolt extractor and sure enough i broke it should of known better so now i had a super...
pillar drill would need setting up just so i am thinking more along lines of reverse drill bit with something around the shaft so it fits snuggly into hole thus keeping it centered and as it has only just been put in i hope it isnt too tight so with reverse drill bit and a bit of luck
its snapped of at the start of the threads which is way down in the engine the only option i can think of is drilling it out but i am open to other ideas
car now going back together if anyone is thinking of doing this job i now have all the tools you need to do it and i will happily loan them to anyone close by that needs them
got a couple of injectors out i found by wiggling the bracket that holds them in first really helps then go on to the grips but the other 2 injectors are not playing nice
thanks i ran the car which freed 2 of them but other 2 tight how much waggling can you get away with ?? and sorry for showing my ignorance but undo caps ??
