    RC 390..top end power loss,overheating,running lean? ,low oil pressure.

    Sure, I've a video I did checking the oil pressure at ~1500 and 4500, as instructed in the 2018 repair manual: As the video shows, the readings look reasonable, perhaps a couple psi low - but certainly no sign of a complete failure that I would expect when seeing that low oil pressure warning...

Replaced oil and filter and pressure sensor twice, all to oem spec. Pulled apart the oil pump, checked passages with no clogs, all looked great and to spec. Oil...
