No, you would not require a rebuild but the best way to do it is to pull the engine anyway. If your engine runs sweet why rebuild. I did this three times because I had a very recycled overheated case that already had casesavers installed, these pulled out one at a time but 30,000 miles later they are sweet and my engine runs sweet. The way I did this was to pull the engine, place engine on a table, remove tin , removed head and inspect for cracks and messed up combustion chambers,while I was there lapped the valves to make shure they are sealing. I then took off BOTH cylinders and pistons (do not mix, keep track of these, clean rings and ring grooves if they are sticky and dirty) , now having all major components removed i was left with the studs. Removed studs with visegrip or opposing studnuts , made sure I knew which studs went where because they differed in length. The pulled casesaver (in you case just the stud) in question was removed by inserting stud with nut and tightened nut down to casesaver then turned stud with visegrip and out came te saver. To fix the problem I had to prepare for surgery by cleaning whole side of case in question with many clean rags and solvent (kerosene and gasoline, im a bad boy). Placed oiled paper towles or oiled lint free rags inside case where the bad stripped hole in question was . Before surgery you should have bought casesavers of the right size for the stud. Drill bit the size of the smallest part of the thread of the saver or a tiney bit smaller , a threader the right size for the saver. Buy these at a machine shop for Veedubs or at an indstrial tool supply. The savers can be purchased in one of the many VW catalogs or VW parts store. The next thing I did was place lots of toilet paper in the cylinder case holes but not inside the case. I had a little jig that makes the drill drill perpendicular to the case. The drill done must be perfectly straight and perpendicular. Many people do not do this themselves because of damaging metal filings falling in, and inaccurate drilling that prevent Cylinder from installing correctly and head seating wrong (lots of leaks). I drilled, being very carful not to drill too far into the hole because if the drill bit went to far it would catch my rags and spin my filings around. After drilling I tapped, the hole keeps the tap straight. I used a vacume cleaner with a straw attachment (You can use a real straw and duct tape). I vacumed quite often and during drilling. The Touchy part for me was carfully removing the filings covered toilet paper and oiled rags . After this I inspected the inside of the case with a tiney mirror and flashlight to be sure no filings fell in. I installed my new casesavers by screwing a stud several threads in and tightening with a nut. I used sealent on the saver to prevent oil from leaking out. Having installed the saver I then removed the stud and the nut. I then installed both pistons in the correct places and positions. I then installed all of the studs with sealant in their correct places. Then the cylinders and heads were installed. I hope this helps you. Do not choose this direction if you are not sure of you own patience and basic skills.
