As I showed in my rebuild thread, I found one of my cylinder heads with an insert for one exhaust stud, but installed at an angle. The other head has one oversize stud hole (9mm?).
My first thoughts: remove the insert and inspect the hole. I may attempt to drill a larger hole at the proper angle and install a bigger insert. If I do that, I may do the same for the other head, which will be the same hole position. Comments? Attached thumbnail(s) |

I use the short cast section cut off of a 71 914 heat exchanger. I bolt it up with the other stud, and use it as a guide to re-drill the hole. (IMG:style_emoticons/default/smile.gif) Keen minds think alike. I did the same but I also drilled it up to accept an actual hardened drill guide. Then got 2-3 guides of varing ID size so I could driil-out the broken stud & preserve the head whenever possible. |
