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 don't drill too straight let alone run a tap straight while on my back.
Do you reccomend removing the head in the car or out of the car ? What is more feasible, taking the head to machinist to weld and check for cracks around the stud bosses OR get another used head. But then what is needed to mate the used head to my block ? Which route is most feasible would you guys reccomend ?? |
