Measuring Engine Oil Pressure
The 1U-5470 Engine Pressure Group can be used in order to measure the engine oil pressure. This device can also be used to determine if there is a restriction in the oil filter.

Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury. |

Oil pressure to the camshaft and main bearings should be checked on the side of the cylinder block at the oil gallery plug. With the engine at operating temperature, the minimum oil pressure at full load rpm should be approximately 280 kPa (40 psi). Minimum oil pressure at low idle rpm should be approximately 140 kPa (20 psi).
