It's OK for the owner to make the field repair rather than replace the part.
To Roy's credit lot's of VW shops used all kinds of shady crap to repair cases, but 99% of them are not in business any more.

Ha, ha.....yeah, I have a couple different levels of how to fix things. Some things I would only do for my own stuff, some fixes I call "desert island" fixes, which I would only do if I was stuck on a desert island and needed the motor to run to get back to civilization, then there are some fixes that are, "I don't want to buy a new one, please make it work" where I warn the customer that it isn't the best or longest lasting fix BUT it will work and is cheap. Then there are some "fixes" that I would never even waste my time with......like buying a hardware store bolt, drilling it out and using it for a case saver. It's really not hard to get a custom insert that is professionally made.

So I got the 5/8” case savers yesterday and got the threads cut and cleaned up today. I used Loctite 592 to seal the threads. The head stud fits a bit loose in the saver so I used the Loctite on that, too. I’ll give it till tomorrow to set up but I’m not optimistic that the stud will stay put. If not I suppose the stud will turn until the threads bottom out which will put 2-3 threads past the end of the saver inside the case. Is that a problem or should I JB Weld the stud to the case saver? I figure this is the last chance for this case but I’d sure like to get this put together now and plan on a new engine build next year.

Lookin' good: plenty of grease on the flutes & about 75% thread.
Now just test-fit the cylinder back into that location - if it can fully seat, you're fine. If not, it's bound-up & needs a bit of dressing-down on the high spot.
Lastly, mock-up the cylinders/head & compare this stud's installed height to its nearest neighbor.

I'm not sure how compression works.
Turbos don't produce torque, they produce HP. Instead of torque.
The real problem with NA engines is you don't hear the nice whine of the turbo as it spools up.
Before I commit, I'm going to do more research because I don't really know what piston rings are. |

The heads are both back on and torqued to 22 ft/#.
The case is saved!
