- Open the filler cap and check the seal for porosity and damage.
- Crankcase ventilation system: For example, check the hoses from the crankcase to the camshaft housing and from the camshaft housing to the air manifold.
- Cylinder head cover seal.
- Cylinder head seal.
- Oil filter seal: where the oil filter housing is attached to the flange.
- drain plug (tightness).
- hydraulic switch (tightness).
- Oil pan seal.
- Front and rear crankshaft and camshaft seals.
Since oil usually spreads over a large area in case of leaks, it was quite difficult to determine the location of the leak at a glance. When searching for leaks, it is advisable to proceed as follows:
Wash the engine. Spray the engine with a standard cleaning agent, after a while, wash everything off the engine with a jet of water. Cover the generator with plastic wrap.
Attention: In order to protect the environment, car washing in open areas is prohibited in most areas. However, at many gas stations it is possible to treat the car using a steamer. Since these stations ensure that dirty water does not seep into the ground, washing should be done there.
Sprinkle connections and seals on the outside of the motor with chalk or talcum powder.
Check the oil level, top up if necessary.
Carry out an inspection trip. Since the oil becomes liquid in a hot engine and therefore flows out faster at leaks, it is recommended that the test drive be carried out over a section of about 30 km on a highway.
In conclusion, inspect the engine using a lamp, find leaks and troubleshoot.
