Have been rebuilding the engine on the 116 and the manual always lists the special tools necessary. Most can be replaced by standard tools but some of them do make life easier. Most recently MB were quite happy to sell me the valve spring tool but now will not sell me the offset hex socket driver for some of the head bolts saying that the parts dept are not allowed to. That so? Were previous sales a mistake? Have seen them on US sites but shipping makes them really expensive.
 
Close, he's after one of these.

Yes that's exactly it. Did try welding one but the welding appeared to soften it and it twisted in to a spiral. I need to put 60Nm on it and all the ones I have tried all 3/8" socket and 8mm key just will not take the load. The MB one is 1/2". The problem is that many of the 18 head bolts on each head are not accessible to a straight hex key/socket. Particularly those under the exhaust manifolds. The only alternative is to strip the heads of cams and manifolds which takes a long time.
