I've got some 'interesting' debris off the 851 sump magnet. Its quite stiff - some bits broke when I tried flattening them to get an idea of whether they would fit together. It has some interesting inward facing 'dimples' which might ring a bell ? Any ideas before I check the bank balance ?
Well, Mr Haynes has some suprisingly good pics for a change. It looks like its a gearbox thrust washer ... and there are 7 of them, so I've no idea which one. At least from racing experience, if it was a 'bad' one to lose, there would be bits of gear teeth to show as well, and there was no other significant debris, just some magnetic sludge to show something is wearing ...
