Engine Repair Tips

  • Never ignore a flashing Check Engine light—it indicates active damage to the catalytic converter or engine internals
  • Follow the manufacturer's timing belt replacement interval exactly (usually 100,000 to 160,000 km)
  • Use the correct grade of engine oil specified in your owner's manual
  • Monitor your temperature gauge regularly, especially in heavy summer traffic
  • Address small oil leaks before they become major engine failures
  • Get a compression test done if your engine has over 200,000 km to assess internal wear

Frequently Asked Questions

Minor repairs like spark plugs or sensors cost $150-$500. Head gasket replacement runs $1,500-$3,000. A complete engine rebuild costs $3,000-$6,000+, while a replacement engine with installation ranges from $4,000-$8,000+.

If the block and heads are in good condition, a rebuild is often more cost-effective and can result in a like-new engine. If there's severe damage (cracked block, spun bearings), a remanufactured replacement may be more practical.

A complete engine rebuild typically takes 2 to 4 weeks, depending on parts availability, machining requirements, and the shop's workload.

The most common cause is engine overheating. When the engine exceeds its designed temperature, the head gasket material warps and fails, allowing coolant and oil to mix or leak externally.
