I have an original 6 engine in my 6 conversion car. I have an oil leak at the stud circled in the pic below. I have tried to torque the nut on this stud without success. I then double nutted the stud to see if maybe the stud and become loose. I was able to turn the stud in a bit so I thought I was making progress. When I removed the double nuts and placed a washer and nut back on to torque to value it won't snug up. Instead, as I torque the nut...the stud begins to turn out. I have a bad feeling about this....Please chime in with your wisdom.

yeah. I measured the original stud and the hole. the hole was significantly deeper than the stud, etc.. I dont think the factory tapped it to the end, so I lucked out. (3R case if that matters...)
I used a bottoming-tap and the stud I used was threaded 'longer' on one end, so I inserted that end. -bob |

I found this on McMasterCarr... Also known as setup and driver studs, these studs are typically used in clamping applications. Inch sizes have a Class 2A thread fit; metric have a Class 6g thread fit. Black-oxide steel studs are made of C1541 steel. The black-oxide finish provides lubricity and mild rust resistance. Studs have a min. Rockwell hardness of C27 and min. tensile strength of 125,000 psi. Those marked with a star have flat areas on the shank that facilitate installation with a wrench. For matching hex nuts in inch sizes see 95479A; for metric sizes see metric hex nuts. |
