Common Engine Problems in Older Cars: What to Watch Out For

Buying a used car can save you money, but it also comes with risks. One major area of concern is the engine. Older cars are more likely to have engine problems that could cost a lot to fix. Understanding these issues can help you avoid unexpected repair bills.

Signs of Engine Problems

Here are some common signs that the engine in a used car might have problems:

Strange Noises: If you hear knocking, ticking, or loud rattling from the engine, it could mean trouble.
Excessive Exhaust Smoke: Blue smoke might mean oil is burning, while black smoke could indicate the engine is using too much fuel.
Leaking Fluids: Look for oil or coolant leaks under the car.
Check Engine Light: This light warns of engine issues and shouldn’t be ignored.
Poor Performance: Sluggish acceleration or difficulty starting could point to engine trouble.

Common Engine Issues

Oil Leaks: Oil leaks are common in older cars. They can happen because of worn gaskets or seals.
- Solution: Have the engine inspected to identify the source of the leak and replace the faulty components.
Overheating: Overheating can damage engine parts. It often results from a failing radiator or low coolant levels.
- Solution: Check the cooling system and top up or replace the coolant as needed.
Timing Belt Failure: The timing belt synchronizes the engine’s parts. If it breaks, it can cause severe damage.
- Solution: Replace the timing belt according to the manufacturer’s schedule.
Worn Spark Plugs: Faulty spark plugs can make the engine misfire or run inefficiently.
- Solution: Replace worn-out spark plugs with new ones.
Fuel System Issues: A clogged fuel filter or failing fuel pump can disrupt the engine’s fuel supply.
- Solution: Clean or replace the fuel system components.

Prevention Tips

Regular Maintenance: Keep up with oil changes, filter replacements, and routine inspections.
Check the Car’s History: Use tools like a PPSR Check $2 to learn about the vehicle’s past. In QLD, where private car sales are common, a VIN check offers peace of mind by confirming ownership, finance status, and repair history. Do a quick and reliable check at VIN check Qld or Revs Check Qld.
Test Drive the Car: During the test drive, pay attention to how the car accelerates, idles, and sounds.
Use Professional Inspections: Consider a pre-purchase inspection from a qualified mechanic. Learn more in Used Car Warranties: What’s Covered and What’s Not.
