Engine

3.5L V6

• Valve Cover Gasket Leaks
  • Description/Symptoms: Oil leaks from the valve cover gaskets, leading to oil consumption, potential engine bay mess, and a burning oil smell.
  • Solution: Replace the valve cover gaskets.
  • Estimated Cost to Fix: $200 - $400
• Timing Belt Failure
  • Description/Symptoms: The 3.5L V6 is an interference engine, meaning that if the timing belt breaks, the pistons will impact the valves causing major internal damage to the engine. Symptoms include engine misfires, ticking noises, inability to start, and complete engine failure if the belt snaps.
  • Solution: Replace the timing belt and water pump according to the manufacturer’s recommended service interval (typically every 60,000 miles). If the belt has already failed, extensive engine repairs or replacement may be necessary.
  • Estimated Cost to Fix: $500 - $1000 for preventative maintenance; $2000+ for engine repair/replacement if the belt fails.

Summary

The 2002 Mitsubishi Montero, while generally reliable, is prone to age-related issues. Engine maintenance, particularly the timing belt, is crucial to prevent costly repairs. Suspension components and electrical systems are also common areas of concern. Addressing rust is vital for longevity. The cost of repairs can vary widely depending on the specific issue and the extent of the damage, but owners should anticipate spending several hundred to several thousand dollars over the lifespan of the vehicle to address these potential problems.
