Engine pinging is a sound you hear inside the engine that seems to be unusual. It is a detonation sound or a loud knock.
This ping sound is a symptom of a problem which can be any of the following:
- Improper timing (over-advanced or under-advanced)
- Improper fuel grade (lean fuel condition)
- Overheating ( lack of oil)
- Improper valve clearance
What are you going to do with this ping?
- Adjust ignition timing.
- Fill with proper fuel grade (regular or premium and do not mix)
- Check engine oil and fill it to the proper level.
- Adjust valve clearance to the prescription of the manufacturer.
In the case of number 2 problem, improper fuel grade can be an accidental incident. Experiences tell that some fuel refilling stations accidentally filled some vehicles with the improper fuel like filling diesel engine with a gas.
The immediate solution to this is, the tank has to be emptied and the carburetor or the injection pump must be dried from the improper fuel.
