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)    |

QUOTE Your best bet now will be to get a M10x1.5 Time-Sert or Heli-Coil kit. This will allow for the installation of a M10x M8 step stud. The O.D. of the Time-Sert/Heli-Coil will be ~12mm. This is required now that you have pulled out a M8 Heli-Coil which, as you can see, has a ~10mm O.D. I did this a couple of years ago with the engine in the car. Go slow, get the angle right and measure the depth ahead of time so you don't go too deep. One of the hardest parts of the job for me was finding a correct step stud. I had to mail order from Canada. No one had 'em or if they did the threads were cut incorrectly. Good luck! |
