tapping case savers

[mlski67]

umm i have a ? i put case saves in with a screw driver (STUPID) this messed the 1st thread up so naturally i got a tap out 10mm x 1.50 this just pulled 2 threads out i think the tap is dicked up ... or is there a special tap i should use ? also if i have to take the case savers uot how should i i also put loctite on them so i doubt they will come out ......any help wouls be appreciated Thanks Mike

The tap to clean up the inside threads of the casesavers is any normal tappered tap, of the correct thread size. On removing them, I use an old stud, either the 8mm or 10mm, depending on the case saver size, put a head nut on it, till it cannot go any further on the threads, then a tight fitting washer, with a small outside diameter, use wide enough to "grab" on the outer surface of the case saver.


When you screw the Stub,nut,washer device into the case saver, you then use a wrench on the nut to tighten it down good. It will usually "grab" the case saver and allow it to screw out of the case. Most of the time. In your case, I would pray first, before doing any of the above. But, seriously, that really does work and cost nothing, if you have some used VW parts laying around.

Missing two threads will not hurt anything, so if you just tap them clean, everything will be okay. I usually use blue locktight on the outer threads, when I install case savers. Why the screwdriver?? use the home made tool, I described to you also to install them, without any damage to the threads or the top outer edge. It works for me.

I do not find the time serts to work good on the vw head studs. On the different case savers, I know that EMPI and Bugpack sell them in packs of usually eight. The 10mm head stud size is usually opened. While the 8mm ones, which are harder to find are closed. I basically recycle the 8mm ones, when I get a bad case. I notice the factory 8mm ones come out of the case more easy, when you remove the head studs. The 10mm , since they grab more surface, usually stand in the case, when you remover the head studs.

The worse case problem I had was a stripped out 10mm case saver, where it had pulled out the threads from the case. Now, what do you do to fix that problem. The 8mm is smaller and another 10mm one will not stay in. What I did, while you all will get a laugh from this was to weld a washer on the bottom side of the 10mm case saver and install it from the inside of the case. This will only work in a few spots on the case as some of the holes are dead ended.. Anyway, I got lucky and I think it was the upper head stud on number one cylinder. Anyway, using some JB weld to seal up the threads between the case and the case saver, that worked and there was no way it was pulling out again. Most people go with new cases, as the price on them has declined, over the last few years.

hey george got the mesedup cases savers out and put new ones in useing your stude trick worked good thx but on the uper # 3 cyl hole it is recessed about 1/2 inc into the block how do you put that one in thx mike

[george4888]

On number three , upper head stud, if you see the stud recessed into the case, that means there is no case saver. I have never seem one needed in that area, but I think you could tap and put one of the 10mm case savers into that hole, but you might need to put some good quality metal expoxsy around the outside of the case saver before you insert it into the case. Usually, the top head studs do not pull out of the case, on any of the engines, as they get the cool air from the fan. The problem is that the lower ones are subject to more stress and more heat from the heads and the cylinders. Also, there is the stress caused by the action of the rocker arms. Notice that the lower head studs are in line with the rocker arms, so they take all the stress caused by the action of the valve train. I am surprised they hold up, as good as they do. I usually put case savers into the old 10mm head stud cases only on the lower head studs, as I stated, I have never seen an upper stud pull out. So, back to the number three upper stud. It should be okay, as is.

If you do put a case saver into that hole, you will need to use the same length head stud as on number four upper right stud.

Hey,,that was a good fix you did using the larger time sert,,then the case saver.. If someone was building up a modified engine,,,they should invest in a new case,,,anyway,,,so this mostly is only for stock engine repairs.....I like your "fix"....George

Shoot. I burned a Std/Std AS41 case because it had a pulled casesaver.

Thanks for the info.

What if the 14mm. Comes out? Is there enough room to do the process over with a 16mm timecert?
