No, but it is in the service manual:
Oil Pressure Measurement
Oil Pressure @2 000 r/min (rpm), Oil Temperature 90°C (194°F)
127 ∼ 167 kPa (1.3 ∼ 1.7 kgf/cm², 18 ∼ 24 psi)
If the oil pressure is much lower than the standard, check the oil pump, oil pressure relief valve, and/or crankshaft bearing wear and con-rod big end bearing insert wear immediately.
If the reading is much higher than the standard, check the oil screen first, and the oil passages for dirt or clogging. Also, replace the oil filter.
