Hi, I have found some old threads with unidentified clattering noises (normally thought to be variatiors) and in some cases strange cup shaped metal pieces in the sump. I had been living with what I thought was intermittent variator clattering noises on start up and installed an Accusump to pre-lube the variatiors but this did not seem to stop the noise. I recently had the sump removed to replace a leaking oil pressure sensor switch and discovered mangled metal and plastic pieces in the sump. You can imagine the feeling of dread as we removed the front timing chain cover! Thankfully? the fault was found to be the oil pump control unit (situated at the base of the motor) that had shattered the tensioners and parts of the chain bracket guide - there were also cup shaped metal tensioner guides resembling piston rod connecting bearings. The replacement part (223267) comes as a complete unit and cost 231 GBP from Scuderiaparts (UK). Hope this helps for all those who find similar signs of a “problem“ although the engine still runs perfectly.
