So the continuing saga of fitting the SS heat exchangers continue. I somehow pulled out the heli coil repair on the exhaust stud. The coil measures 9.5mm OD.
I suppose I need to re-tap the hole with a step stud. So what size step stud should I use ?? M8 to (M10 or M11) ? Where would I find such a stud ? Is it do-able, drilling and tapping from under the engine ? How the heck am I going to keep the bit and tap straight and not F/up ? Man it never ends with old cars...... (IMG:style_emoticons/default/ar15.gif) Thanks in advance for everyones help !!!! I really appreciate it. (IMG:style_emoticons/default/beerchug.gif)    |

I think more luck than precision ......................Repairing stud holes under a 911 using a drill guide is difficult enough. Doing the same on a 914, especially with a hogged out hole for a guide, is much harder, especially as the holes are at an angle to the rest of the head.
