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.

By the sounds of things the stud is pulling from the magnesium.
In order to fix it you will need to split the case and install an insert. Sorry for the bad news but there's no other way to fix it. |

Well that was what I was afraid of...I will just have to watch the leak CLOSELY and deal with the mess is makes...Really sickening...I guess these old Mag cases are pieces of shit now due to their age. I had inserts done on all of the head studs when the engine was rebuilt...the rebuild only has about 5-10K miles on it. Didn't consider having all the case studs inserted as well. by the way...I just spent $14K on a rebuld of our 3.2 911 engine and their are absolutely no funds to pay for this kind of deal on the 914 now... Anyone else have and more wisdom? |

Anyone else have and more wisdom? I hear you 911 engines are not cheap to rebuild. I had Ollie's do some work on my 2.7 case years ago. I had them install case savers, shuffle pins and inserts on all of the studs within the case. You may try the epoxy route but I don't think it will last too long. |
