Common Symptoms of Engine Issues
1. Unusual Noises
One of the first signs that something might be off is the presence of unusual noises coming from the engine. This can include:
- Knocking or tapping sounds, which may suggest issues with the engine’s internals.
- Grinding noises, indicating potential problems with the bearings or other moving parts.
- Hissing or popping sounds, often related to exhaust leaks or overheating.
