Soooooo
I am installing the exhaust manifolds today, using the nice little copper coated exhaust nuts from Bel Metric and at the point the self locking threads encounter the stud, the stud just starts turning. Little effort to pull it out and the stud is clean, no material in the threads. Now mind you that these heads have just been rebuilt and fixing exhaust studs was on the to do list and the cost was substantial to me. Then the fireworks went off... (IMG:style_emoticons/default/ar15.gif) (IMG:style_emoticons/default/hissyfit.gif) As the great poet Eric Burdon said in the song PC3 "I rattled so long And rattled so obscene The ground did shake And disturbed the Queen..." This is the motor in my Notchback and it has taken too long to squeeze that puppy in there so this fix is going to be in site. Is it an optical illusion or are the studs at an angle? ie not perpendicular to the ground? I ordered some EZLOCK solid inserts and I will make a drill guide that will bolt onto the other stud. Apologies to the neighbors (IMG:style_emoticons/default/blink.gif) |

I did that too, I was torquing the bolts down, but did not realize that the torque wrench did not lock, all of a sudden the stud is going round and round.
Looked at the torque setting, it was 200 in/lbs, just a little excessive. LOL |

LOL I would not have been as mad but these heads had just been rebuilt, fixing all studs was the first request, and this stud was barely in there. I will assume someone set it in there and forgot to check. It required only two fingers on the wrench to spin everything so it had not been repaired. |
