Anyone know the acceptable ranges for oil pressure on an o-290 lycoming?

I can tell you that on an 0-320, with a pressure pick-up coming off of the
accessory case, the "green band" is 60-100 PSI in cruise, with as little as 25 PSI OK for idle conditions with a warm motor. KB "Justin H" wrote in message ... Anyone know the acceptable ranges for oil pressure on an o-290 lycoming? |

For the O-435 series, which is the 6-cylinder brother to the O-290 series, the FAA Certification Sheet shows 60 psi min and 85 psi max. I might point out that both engines use the same rods, rod bearings, pins, pistons, cylinders and valves. I am not sure about the main bearings, however. If you can get hold of the FAA Type Certification Data Sheet, you will have an accurate answer. |
