As discussed in Part 1, cars get their power required to function properly from their heart, the engine. Damage to the engine will have a major effect on vehicle performance. Part 2 will cover four more symptoms of engine damage that should be repaired as soon as possible to prevent further damage.
5) Oil Patches
Oil patches beneath the vehicle are usually from an engine leak. When oil is depleted, there will be greater friction within the engine, generating excess heat and causing damage over time. The most typical oil leaks occur due to faulty engine oil seals, sump plugs, and sump plug washers.
6) Rough Engine
A rough-running engine will vibrate, stutter, or lose power as revolutions increase. Typical repairs to fix this problem are replacing the spark plugs and ignition coils, checking fuel pressure, cleaning the air flow meter, and getting a tune-up.
7) Smoke From Exhaust
The causes of smoke coming from the exhaust can be often determined by its color.
Black smoke indicates that an engine’s fuel combustion is incomplete, resulting in burning excessive fuel due to the problems below:
- Clogged fuel return line
- Damaged fuel injectors
- Dirty or damaged air filter
- Faulty sensors
- Mechanical damage inside engine
Gray smoke can be a symptom of several issues, and it is more of a challenge to diagnose. The probable causes include:
- Greater than normal oil consumption
- Stuck PCV valve
- Transmission fluid problems
Dark blue smoke indicates that an engine is burning oil because it is leaking into the combustion chamber. The reasons are listed below:
- Damaged valve seals
- Damaged or worn engine components
- Worn out piston rings
8) Strange Odors
Emissions should never be smelled by passengers within the vehicle. The smell of exhaust, engine fumes, and strange odors could be symptoms of engine damage.
