Checking the lubrication system (Priora 2170)

1. Open the hood. Do not rush to check the oil level in the engine immediately, let it drain into the oil pan, this will take two to three minutes. During this time, carefully inspect the engine to find out if there are any fresh oil leaks.

2. Look under the front of the car to see if the engine oil pan is punctured or if there is a leak.

Note: If oil is found leaking from a punctured oil pan, try to temporarily seal it in place. For this purpose, you can use a car inner tube, a piece of rubber, a rag, a wooden plug, etc. A good result can be achieved by using modern repair materials such as "cold welding", which are available in auto stores.

3. Pay special attention to the oil filter. Oil may leak from under the rubber filter seal if it is damaged or the filter is not properly secured. If oil is leaking from under the oil filter, sometimes it is enough to turn it a little clockwise.

Warning: Be careful: hot engine parts can burn you, so wear gloves and long sleeves.

4. Remove the dipstick, wipe it with a clean cloth and reinsert it.

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 level.

Note: If you don't have a funnel for adding oil, you can use a funnel made from the neck of a plastic bottle.

7. Start the engine. If the oil pressure warning light goes out when the level is normal, you can continue driving. If the lamp does not go out, check the serviceability of the oil pressure sensor. It is mounted at the top rear of the camshaft bearing housing. Unscrew the standard oil pressure sensor 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 rotation speed, the sensor or its electrical circuit is faulty.

Note: If you do not have a pressure gauge, the only option left 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 (the oil pressure warning light is on), perform diagnostics and repair of the engine (see section. "Engine").
