@@KoenigsTiger957 Yes it is not unusual for people to Loctite the studs into the case. When you install the new inserts you can use a little bit of red Loctite on the insert and just make sure the installer bottoms out in the hole.
@@klassikats Yeah, the stock VW case savers are pretty odd, they don't have a locking mechanism like a time-sert. The some of the cylinder stud hole are straight through... Seems to hold the measly 18 lbs. I wonder how much torque is applied as the engine heats up...
@@KoenigsTiger957 Yes the "case Saver" brand is just a straight piece of steel with an M14 thread on the outside and an M10 thread on the ID. I have never found them to be very reliable at staying installed. With those inserts, you have to rely on Loctite to retain the insert. There are several types of "Case Savers" out there. Some do have types of locking systems and some don't. I personally don't use anything but the Time sert inserts. If for no other reason that once you properly expand the insert you have a solid and positive mechanical bond between the case and the insert. Unfortunately, you are limited to whatever thread is cut into the case at the moment to what insert you can install...
Fantastic Video's Kurt!!! When doing this on a 2.7, the spigot wall gets very thin (1.3mm or so) at the thread-serted hole after counter boring with the 1/2" end mill. Have you had any trouble with cylinder sealing here? Thank you.
Love your videos and appreciate your attention to detail as well as your ability to convey your work on video. Was wondering if you might be able to help with something. I have a 76' 911s with a very tired, 2.7 , low compression & pulled head studs engine which requires a case split & machining. My mechanic is has informed me that there's a big delay due to the shortage of quality parts, (he won't use parts from China) for the case, including serts, valve guides & all that's necessary to completely rebuild the case. Wondering if anyone's heard of these problems and where one might find all the parts necessary to properly rebuild a magnesium 2.7 liter engine case. Very much appreciated. -J
So not sure who your mechanic is and yes sometimes parts supply can be an issue however, we are not experiencing any major delays. There are also not a lot of parts for these engines that come from China either. There is just not the demand to warrant someone to invest the money in manufacturing. Now there are some items that are made in China like pistons and cylinders. However the original Mahle pistons and cylinders are still available, they just cost a lot more. The companies where we buy our parts are only available to resellers and they do not sell to the public. There are however plenty of companies out there where you can buy the parts. Companies like Partsklassik, Pelican, ECS Tunning, and Autohaus AZ will be happy to sell you the same parts that we use. hope that helps Kurt
It sure does. Thx you so much! Do you offer rebuild services for that engine? If so, what would the ball park costs be and turn around time? Again, thx for the replay. @@klassikats
They both work just fine. I am just used to using time-serts as that is what we used when I worked at the dealer and just continued to use them in my own shop. Kurt
Is this procedure done when the head studs don't hold properly on the case!..If you are doing an engine rebuild and the studs are all good when disassemble ,can you just reassemble with new studs without this procedure!..thanks
Mike, I guess I never will as I have learned my lesson. Years ago I let a customer talk me into not doing inserts to save a few dollars. He had the express understanding that if there was a problem later down the road, he would be responsible for the expense. The engine didn't last 2000 miles before pulling one entire lower right bank of studs. Luckily I had everything in writing and signed by the owner. However, he was still mad, and it is never good to go back in for something so simple that should just be done in the first place. But it is up to you Kurt
Beautiful work, thanks for taking so much trouble with the video.
You're very welcome!
Kurt
Great video, really nicely done.
Thank you! Cheers!
Great video! My volkswagen saver came out with the stud... thank you very much for explaining the install process!!
your welcome, usually when the insert comes out with the stud it means that it was not properly expanded when it was installed.
Kurt

That's got to be it. It seems like the studs were loctited into the inserts...

Never have any issues with sealing even with the small wall thickness. Just make sure everything is flat.
Kurt
Great vid.
Thanks
awesome! I want to go to this school!
Thanks Ryan
Well, I am definitely going to need the install tool now...
I tapped the old hole, now the old time sert is loose...
Here is the link to the install kit, amzn.to/3ooPPXd . good luck with the install.

Beautiful, what treatment the crankcase seeds have undergone ... they look like new
Thanks

You prefer the time serts over the case-savers on meg case? So many mixed reviews.
They both work just fine. I am just used to using time-serts as that is what we used when I worked at the dealer and just continued to use them in my own shop.

@@klassikats OK Thank you Kurt!..you saved me a whole lot of worry!..thanks again!
Do you use time Certs even if there currently is not any thread damage?
On a Magnesium case, always. S
