Removal
1. Remove the intake manifold (see the relevant chapter).
2. Drain the engine oil (see the relevant chapter).
3. Cars with a 4.2L petrol engine: Unscrew the oil filter cap (see arrow in illustration).
7.3 Unscrew the oil filter cap (see arrow). Cars with a 4.2L petrol engine
4. Diesel vehicles: Unscrew the oil filter cap (see arrow in illustration), using a special key.
7.4. Unscrew the oil filter cap (see arrow), using a special key. Cars with a diesel engine
5. Wrap the oil filter housing with a rag to collect any remaining oil.
6. Cars with a 4.2L petrol engine. Remove the bolts (see arrows in the illustration) fasteners and remove the oil filter housing.
7.S. Unscrew the bolts (see arrows) fasteners and remove the oil filter housing. Cars with a 4.2 L petrol engine
7. Replace the replaceable filter element 3 and sealing ring 2 (see illustration).
7.7. Replace the replaceable filter element 3 and sealing ring 2
The oil filter is installed in the reverse order of removal.
Visual inspection of tightness and oil leaks
If the engine is contaminated with oil, or if oil consumption is high, determine where it is leaking. To do this, inspect the following places:
8. Open the oil filler cap and check the gasket for porosity and damage.
9. Check the crankcase ventilation hose, especially the section between the cylinder head cover and the air filter.
10. Check the cylinder head gasket.
11. Check the sealing ring of the oil drain plug.
12. Check the oil filter gasket, which is located between the filter and the filter mounting flange.
13. Check the oil pan gasket.
14. Check the camshaft and crankshaft seals.
Since the leak usually spreads oil over a large surface area of the engine, it can be difficult to determine the leak location at first glance. The following search method is recommended:
15. Wash the engine. To do this, spray the engine with an aerosol cleaner and, after letting it work, rinse with water. Before doing this, cover the generator and fuse box with a plastic bag.
16. Sprinkle the outside of the connecting joints and their gaskets with lime or talc.
17. Check the oil level and top up if necessary.
18. Take a test drive. Since the oil liquefies when the engine is hot and therefore leaks faster, it is best to take this drive on a highway, covering a distance of about 30 km.
19. Inspect the engine after the test drive, illuminating the inspected areas with a flashlight, and identify the oil leaks. Eliminate any faults found.
