Cylinder Head Bolts - 230E Cylinder Head removal tool?

[Anonymous]

My old 230E, 4 cylinder petrol , W124 engine, has gone and bust a head gasket... It's head must come off..! When I get to the head bolts I notice the socket I need is something like a multi-spline bit, 12 or 14 pointed star...Does anyone know what the bit is that I need, and where it can be bought?

I can't remember the size but its a standard spline tool, available at halfords and the like.
You should note, however, that the bolts are stretch bolts, unless you have the specs and a micrometer to check them, they should be replaced
