I have a Lycoming o-320 A2B that was a field overhauled engine and I have been fighting with high oil temperture 220 F and corresponding low oil pressure, as low as 40 PSI. I have been going through the oil system and I changed oil, oil filter, cleaned oil screen, replaced vernatherm and flushed oil cooler. It appears that oil might still be bypassing the oil cooler...? Oil cooler is not getting very warm and very little oil drains out out of the cooler upon removal. Any ideas were to go from here??
