Snapped exhaust manifold stud, Also snapped EZ Out
Hey All,
The rear top manifold bolt snapped about 2mm inside the head when removing the manifold on the weekend, drilled out the stud and when removing also snapped the EZ out inside the thread 😑. I know this is a nightmare as ive spent the last two days trying to redrill and get a new centre but because of the hardend steel its been difficult and pushing my drill holes to the side. Ive managed to get the hole recentered and slightly larger but i cant get any depth in this new hole and blunted 10 brand new 3mm drill bits.
Ive tried a new set of ez outs different from the ones is snapped, theyre left hand spiral self tappers but cant get a deep enough drill hole for them to bite.
Have anyone got any ideas as im scared to keep at it with drill bits that dont go nowhere and i dont want to butcher it more than i already have.
Thinking its best to take it to the local exhaust place and get them to look at it? Thats probably my sadest bet right? Couldnt find any mobile local tread specialist in the Liverpool NSW area. And dont really want to remove the head if i dont absolutely have too.
Cheers
