Case-Savers & Engine Studs
Why use case-savers?? Well as the name implies, they will save your case!! Many of the older VW motors didn't come from the factory with these installed. It is not un-common to have studs pulled out of these motors causing heads to loosen and eventually warp. Studs pulling out is a BAD thing. Using case savers tends to solve this problem (or at least make it easier to repair if it does happen.
Above are 2 shots of the two different kinds of case-savers out there. I know it's a little difficult from these photos to tell there is a difference between these two types, so bare with me here. The LEFT photo is of an older style 10mm found in most SOPR cases. The CENTER photo is a DOPR case with the newer style 8mm case-savers. Most prefer the newer 8mm variety. The RIGHT photo is of the deep set case-saver on cylinder #3's the top-front stud.
This photo is of a case with 10mm studs that are made for single port heads. If you look closely you will note that the 4 top studs are all the same length. On engines with dual port studs, the 2 center, top studs will be about 1/2" SHORTER than the other 2 studs. If the case you are considering has the wrong type of studs for your application, it will probably cost you up to $30.00 to get a set. Remember that you could go to your local pick-n-pull and just get the top center studs that you need off a junk case for just a couple bucks (if that).
