Stripped case saver...What are my options?

[T2 The Boss]

Hello.
I've purchased dual relief case with 10mm studs, which is overall in good condition except the savers that were installed after the studs pull out from the case.
Unfortunately someone puted self tapping savers 14mm which are almost ready to pull out...
What are my options now? Can I make custom savers with the following parameters - outer diameter 16mm and inner 10mm or even 8mm so I can use later type studs?

you could...but will the time/effort to do so be worth it vs. just starting with another case?

sound like several hours of work

[evanfrucht]

You say they are just loose or feel like they could come out easily?

I'm no expert on this but I would think if you remove all of them and then re-install new ones ( or possibly even the same ones just cleaned very well ) using some kind of locktite it might just work fine.

The sell a green colored type called retaining compound (loctite 290 is the number?)

Be extremely careful if you drill it yourself to make sure the drill goes in absolutely straight up and down. A while back there was a nightmare engine case someone had with the studs protruding at weird angles due to misaligned drilling.

I wouldn't even think about hand drilling but would use a quality drill press, or, better yet send it to a vw machine shop and let them undertake that task.

Good luck

There is no such thing as "self tapping case savers"

There is a stud with slightly oversized threads. The threads are cut like a tap... those are called "self tapping studs" but are not that common and even if someone did use those you should still be able to have a machine shop tap the case for regular 14mm OD case savers.

Its hard to tell what the actual problem your having is from the photo and description provided.

Is the problem simply that a few of the case savers have backed out a little and are loose?

The description for these Time-Serts indicate they would serve your purpose, though you'd end up having to use 10 mm head studs. http://vwparts.aircooled.net/Big-Sert-Thread-Repair-Insert-10-x-1-5-x-20mm-p/50153.htm

In addition to buying 1 for every head stud (16x) you'd also need to rent the installation tool/kit. And then you'd still need to drill the holes in the case accurately. Are all 16 of the case's stud holes stripped, or are there some that can still use new 10 mm stud case savers + thread lock compound?

Same vendor also sells case savers for case holes that first had 10 mm studs but would now use 8 mm studs.

Remember also that the head studs themselves do not need to be run all the way into the case savers and then torqued down or tightened. Instead, and this is something I only learned here on theSamba in the last maybe 10 years, is that you run the stud down by hand until it stops, then back it out a small amount such as 1/2 turn. So if your solution to the case savers ends up using your 10 mm head studs, run an M10 x 1.5 mm die over both of the threaded ends so that they turn easily into the new case savers.

Yes, if you bottom studs out, then torque them down and the turn some in the bottomed out thread,you will distort the stud thread and or the hole thread, then when they are removed,you can damage the threads, best to back them off at least a 1/2 to full tread then mark, so you can see if they turn while torquing, some studs have a different fit at each end for this purpose.

Is that really a dual relief case? I thought they were all AS41 or AS21 cases.
