To All, Yesterday. After my case came back from the machine shop, i pulled it apart. I had them install shuffle pins (among other things). These are known to make splitting the case a CHORE, i found out that using an old head as a puller works fine. You have to unbolt the #1 & 2 rods if the case still has it's internals. slide on the (preferably old) head until it bottoms against the 6 big case studs, use studs, bolts, spacers and/or whatever in the cylinderheadthreads in the case, just to tighten the head *lightly* to the case. If you have to apply much force: do not use this method on threads you have to reuse. ONLY use this trick on a casesavered case, or one thats gonna be. I did not have to apply much force, although you'd expect it, the force is now distributed evenly over a large area. Make sure every bolt or stud that's going to be screwed into a case thread is clean and undamaged, and that ALL case bolts/nuts are removed, including their washers and any sealer from the studs, or ANY foreing material, it can jam a stud in its bore. Now something else, this very case is getting quite expensive, i can recommend a brand new (TI) case to anybody, even (maybe especially) economically minded VW rebuilders. I pulled some oilgallery plugs to gain access for cleaning, i opened the reliefvalves also, when i looked into the rear plungerbore my jaw fell to the floor: somebody (me,@#%$^) had used too long a bolt to attach the rear enginemount, it created a 1.5 mm mountain in the plungerbore :( I'm still thinkering about how i'm gonna solve this, maybe a Hoover (tm) Ball- Valve and a threaded plug in the bolthole... So everyone who has a TI engine with rearmount holes: Check this, it's easily caused and/or overlooked. You don't want to know what happens if this valve is stuck in its bore. Brian.
