rebuilt another Pavoni Europiccola, this time a Millennium version. the group to boiler insert, part number MP-1, had cracked and the machine wasn't behaving correctly.
I couldn't find where the Millennium-specific O-ring went, and wasn't sure which was the right group gasket, but otherwise everything still seemed to go together all right. the L-shaped brass tube should only be turned two full turns then enough to make it vertical, to avoid cracking.
anyway, the damned thing still doesn't work correctly. on lifting the lever all the way, the coffee squirts violently out. there is no back pressure on lowering the lever, in fact it is automatically forced down on releasing. something is still wrong.
