I have a 2.0 type IV from a 914 in my 912, it has the GA heads and Weber 40 IDFs. Today I was warming it up to change the oil and saw flashing from the intake manifold/head seal area when small backfires occured. Naturally I started to tighten the intake manifold bolts. On the #1 cylinder outboard nut, I felt too much play. I wiggled the stud and pulled it right out!
See the picture below. I was able to find more threads in the hole and thread it back in using 2 nuts so it isn't completely stripped. Only about 1/4" of threads came out with the stud. What should I do here?  |

Whoever installed it backed the stud out because it was to short for the carb manifolds thicker flange. Try a longer stud to catch the remaining threads and if that doesn't work you will need to helicoil it.
BTW someone is bound to say helicoils suck and use a time-sert, yes they are better, but in this case there's little torque/load so a helicoil will work just fine. |
