I'm willing to bet that the metal in the oil filter housing is not magnetic, but from the main & big end bearings - hence the lack of oil pressure (flashing oil light), coupled with very thin, high temperature oil.
Regarding the oil feed to the DOF, it may well work on paper and maybe for street use but CrisZenith was driving "flat out for an hour and a half" which puts into question the possibility of oil starvation to the bearings. Especially taking the oil feed from the cylinder head and not the oil filter area.
Sometimes robbing Peter to pay Paul is not always successful. I think I'll stick with my simple LN ceramic IMS bearing which has been in the engine since 2010......
