The first signs of engine damage should be eliminated as soon as possible, as they can lead to consequential damage. In the worst case scenario, the result is a total write-off: the engine fails, the vehicle breaks down and the defective engine has to be replaced. Damage to the engine not only poses considerable safety risks for the driver and all other road users, it can also be very expensive. Pay attention to the following abnormalities when starting and while driving:
Starting problems or “stalling” the engine
Persistent fuel odor
Unusual noises from the engine compartment (clacking, rattling, knocking)
Reduced engine power
Increased oil consumption or loss
Loss of cooling water
Thick white or blue smoke from the exhaust
Foam build-up on the inside of the oil cap
Dirt or even metal chips in the engine oil
