I don't think that - if your only engine instruments are oil temp and pressure - normal readings on those are a good guide to a good engine, because in a Lyco the oil pump is a constant volume (gear) pump which feeds a spring loaded pressure regulator valve which will maintain a constant-ish pressure over a fair oil temp range, and the oil temp itself will take a long time to rise, if at all, if there is a localised mechanical problem such a bearing about to seize.
