I had an MGB motor years ago that suddenly had high oil pressure. One of the
cam bearings had spun in the block and it was blocking the oil flow. Even a
fully open relief valve wasn't letting enough oil escape. It eventually failed
as the oil was supposed to flow around a groove in this bearing and on to
lubricate other parts of the engine,
