rice-pudding Posted July 1, 2015 Posted July 1, 2015 So trying to reverse drill the broken header bolt out and I've some how managed to actually to break the hole instead, as in a piece broke off the edge of the hole on the head itself. Not a happy chap. What's my options here? New head? Quote
Stu Posted July 1, 2015 Posted July 1, 2015 you can get them welded up and then drill and re tap them Quote
rice-pudding Posted July 1, 2015 Author Posted July 1, 2015 I think I'll just get a shop do to that. Just dreading the price it will cost! Quote
Grumpy Old Git Posted July 2, 2015 Posted July 2, 2015 you can get them welded up and then drill and re tap them Easy welding job - should only take a few minutes. The longer time / effort will be smoothing it down and re-drilling / tapping.Get the price for a used head / engine and use this as a guide for the weld job quotation - Go for whichever is cheaper.

rice-pudding Posted July 2, 2015 Author Posted July 2, 2015 Crisis averted (I think). Managed to get the rest of the bolt out the hole. Screwed one of the old bolts and it takes a decent hold on the remaining threads. A shed load of locktite and maybe a spot weld for extra safety and it will be the next owners problem! Now just to get the other 2 out, hopefully I will have learnt from my mistakes.......... Quote
Stu Posted July 2, 2015 Posted July 2, 2015 fit a stainless stud and use brass nuts the stud will seize in as it will react with the alloy head and the brass nuts will strip or shear if things become a bit tight on the next removal with brass been softer its easier to remove those and clean the threads up and good job on getting it out Quote
