help (stud removal)

[looneydrift]

i had 3 break on me and i got 2 out drilled small hole in centre and taped in allen key or star head and wind it out need a real good bit for it. 3rd one just wouldnt turned wouldnt grip so a lad drilled it out bigger and put in a hellicoil. just very hard to get at

did it a few times before tap the centre wit a punch and go get good drill bits sometimes an angle drill is neeeded to get in at it depending on where the stud is next get a stud extractor there like a screw except they have a left hand thread screw tis in till it gets tight then carefully keep twisting till it comes out
be carefull when your drilling thou not to drill into the block
also if its only one stud u might get away wit leaving it as it is

thanks lads its the last stud by the back of the engine so i dont thing ill get away just leaving it out , we were trying to drill it out with a 90 degree drill bit but cant get enough force on it , so im thinking we should take out the abs to give us more spece so we can fit the drill in

thanks for the tips guys the last thing i want to do is take the head off cos i have fuck all money

Make sure you have the exhaust ports blocked up so swarf from the drilling doesn't end up inside the cylinders.

this is the same one that snapped on mine , we were going to take the head out but ended up welding another bolt onto the cracked one , dont know how long that will last but its worth a shot before we take off the head

it was the same one for me and i had the lad drill it out and fit the hellicoil never had to take head of
