Can This Case Be Saved?

[SevenOaks]

Type 1 H case. 10mm head stud in 14mm case saver pulled out of the case when torquing the head. Is there any way to repair this or am I buying a new case?

The case can be saved.
I have rented this tool and installed Timeserts from AC.NET. Well worth the $$.

Good Luck.

I found that, too, when searching for a solution. Unfortunately, that calls for a 31/64” drilled hole but a 1/2” drill bit is loose in the existing hole.

Perhaps one of these would work

And remember: you stated that 1/2 drill bit fits readily into the hole; well the TimeSert Big Sert then has a tap to tap larger threads. I don't have information what thread/diameter the outside of the Big Sert has.

Could just make an insert any size you need. Example, take a 5/8 bolt. Cut the threaded end as long as the saver needs to be then tap the inside to 10x1.5mm. Now tap the hole to 5/8 and be done with it.

Might try the next size up: I've used 5/8-11 TPI savers. Requires drilling to .531" (17/32)".
Looks like an H0 case & BTW the saver to the immediate left of that pulled one appears ready to "exit" as well ....... how did that guy hold torque?

I would go that route by replacing the case saver. Happened to us last century on an engine. The machinist called it an over size case saver. Worked great.

I’ll have two case saver savers on the way to me tomorrow. Thank you all for the tips!

not saying you shouldn't repair this case, but since it originally didn't have case savers that means it's already been fixed before and probably has had a rough life....make sure it's worth saving

[rugblaster]

[nsracing]

Yes of course it can be saved. It will take some machining is all.

[SevenOaks]

If the repair fails then I’ll buy a new case. It’s worth the $5 investment in a case saver saver to give it a try. Engine was running strong before. I only took the heads off to replace leaking push rod tubes.

Do not torque the heads down any more that 22 ft/lbs. If the head gets too hot it will pull studs again. The problem is 10mm head studs are tooo strong for the case. If the first case savers installed were 8mm stud inserts you would not be having this problem.

Anyone sell 8mm studs with 10mm threads ?

[Dan Ruddock]

Years ago Rimco would grind down the non thread area of 10mm studs but afaik they are NLA. Dan

In 30+ years, that has only happened to me once. I threw the case in the garbage. If you can pull one stud insert, what's to stop the other ones from pulling? And for what, an H case? It seems like a very unnecessary risk to take when building a motor. I certainly wouldn't sell somebody one with a fix like that and put a warranty on it.

Again, I only took the heads off to replace leaking push rod tubes. It’s not a rebuild. Every step I take with this engine is a learning process. You can learn more about engines with an old problem one than a shiney new one. I won’t mind having a new one someday, even if that’s sooner rather than later but in the meantime I’m starting to learn how to do some stuff for myself.

I found out that the "H" cases are some of the softest case VW made. when i redid my H5 case i pulled a few threads, case saved anythin g that pulled.
