  • Solution: Depending on the severity, solutions range from using a higher viscosity oil, using additives to help seal the rings and valve seals, or replacing the valve seals or piston rings. In severe cases, a complete engine rebuild may be necessary.
  • Estimated Cost to Fix: $300 - $5000+
  • Recalls: None Found
• Lifter Failure
  • Description/Symptoms: Ticking or knocking noises from the engine, especially at idle. Can lead to misfires and reduced performance.
  • Solution: Replacing the failed lifters, and potentially the camshaft if it has been damaged.
  • Estimated Cost to Fix: $1,500 - $3,000+
  • Recalls: None Found

Transmission
