2. Locate your engine's oil pressure sensor for the instrument cluster indicator (pic. 2.2, a, b).
3. Unscrew the oil pressure sensor and screw the manometer into place (You may need a suitable adapter for this).
4. Connect an accurate tachometer to the engine following the engine manufacturer's instructions.
5. Measure the oil pressure with the engine fully warmed up and running, and compare the results with technical data at the beginning of this chapter. If the measured pressure is significantly lower than the specified pressure, then the bearings and (or) oil on co with worn out and need attention.
