OM603 turbo/cylinder head removal

[sixto]

Looking at the CD manual section on removing the turbo (09-150), there's an oil feed line to the turbo but no drain line. There's also a bracket from the compressor housing to the engine.

Is there or isn't there a drain line to be disconnected?

Does the bracket attach to the head or to the block?

Can the head be removed with the cam and intake manifold in place?

Thanks,
Sixto
