2. Look under the front of the car - if the engine oil sump is broken, if there is a leak.
Note. If an oil leak is found from a punctured oil sump, try to temporarily plug it in place. To do this, you can use a car camera, a piece of rubber, a rag, a wooden cork, etc. A good result can be obtained by the use of modern repair materials such as «cold welding», available for sale in car dealerships.
3. Pay special attention to the oil filter. Oil may leak from under the rubber filter gasket if it is damaged or the filter is loose. If oil is leaking from under the oil filter, sometimes turning it clockwise a little is enough.
Attention! Be careful: hot engine parts can burn you, so wear gloves and long sleeves.
4. Remove the dipstick, wipe it with a clean rag and reinsert.
5. Remove the dipstick again and check the oil level. It should be between the upper and lower levels of the grid scale.
6. If the oil level is below the lower mark on the scale, add oil to the norm.
Note. In the absence of a funnel for adding oil, you can use a funnel made from the neck of a plastic bottle.
7. Start the engine. If the emergency oil pressure drop lamp goes out at a normal level, you can continue driving. If the lamp does not go out, check the oil pressure sensor. It is mounted at the top rear of the camshaft bearing housing. Unscrew the stock oil pressure switch and install a mechanical pressure gauge in its place. If at normal idle speed the pressure is more than 0.1 MPa (1.0 kgf/cm2) and increases with increasing speed, the sensor or its electrical circuit is faulty.
Note. If you do not have a pressure gauge, all that remains is to check the reliability of the contact in the block with the sensor wires or replace the sensor with a known good one.
If, after eliminating all visible causes, the oil pressure in the engine is insufficient (oil pressure warning light on), diagnose and repair the engine (see sect. «Engine»).
Attention! Do not try to drive to the garage: the engine will fail. Have the vehicle with the engine inoperative towed for repair.
Note. Before repairing the engine, check the condition of the oil pump (see «Oil pump repair»).
