- A) no noises or knocks in the engine (see «Engine - condition check»), indicating cranking of the connecting rod or main bearings or a malfunction of the oil pump;
- b) the engine is filled with oil with the appropriate characteristics (see «Lubrication system - oil and oil filter change»);
- V) the oil level in the engine crankcase is correct (see «Checking the levels of technical fluids») and there are no oil stains under the engine;
- G) the oil pressure sensor is working and its wire is not shorted to ground (see «Emergency oil pressure sensor - check and replace»).
Warning! Operating the vehicle with emergency oil pressure in the engine will result in serious engine damage and costly repairs.
A pressure gauge is required to determine the exact oil pressure in the lubrication system.
Execution sequence
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
2. Remove the emergency oil pressure sensor (see «Emergency oil pressure sensor - check and replace»).
3. We wrap the pressure gauge tip into the sensor bore.
4. We start the engine and check the oil pressure. For a serviceable engine warmed up to operating temperature, the oil pressure at idle speed must be at least 30 kPa (0.3 kgf/cm2).
If the pressure is low, the oil pump is faulty (see «Oil pump - removal, inspection and installation»), worn crankshaft liners or the crankshaft itself (contact a specialized service for verification).
