Engine

5.9L V12 Engine

  • Oil Leaks
    • Description/Symptoms: Oil leaks are a common issue, often originating from the valve cover gaskets, oil pan gasket, rear main seal, and timing chain cover. Symptoms include visible oil drips under the car, a burning oil smell, and low oil levels.
    • Solution: Replacing the leaking gaskets or seals is the solution. Thoroughly cleaning the affected areas is also important to prevent future leaks.
    • Estimated Cost to Fix: $500 - $2000+ (depending on the location and severity of the leak)
    • Recalls: None Found
  • Cooling System Issues
    • Description/Symptoms: Overheating is a potential problem, often caused by a failing water pump, radiator, thermostat, or coolant hoses. Symptoms include high temperature readings, coolant leaks, and steam coming from the engine.
    • Solution: Replacing the faulty components. It’s also recommended to flush the cooling system to remove any debris or contaminants.
    • Estimated Cost to Fix: $300 - $1500+ (depending on the component needing replacement)
    • Recalls: None Found
  • Ignition Coil Failure
    • Description/Symptoms: The V12 engine uses individual ignition coils for each cylinder. These can fail over time, leading to misfires, rough running, and a loss of power. The check engine light will often illuminate.
    • Solution: Replacing the faulty ignition coil(s). It’s often recommended to replace all the coils at the same time for preventative maintenance.
    • Estimated Cost to Fix: $200 - $800+ (depending on the number of coils replaced)
    • Recalls: None Found

6-Speed Manual Transmission

  • Clutch Wear
    • Description/Symptoms: Clutch wear is a common issue with manual transmissions, especially with spirited driving. Symptoms include clutch slippage, difficulty shifting gears, and a high clutch pedal.
    • Solution: Replacing the clutch disc, pressure plate, and throw-out bearing. It’s also recommended to resurface the flywheel.
    • Estimated Cost to Fix: $1500 - $3000+
    • Recalls: None Found
  • Synchro Wear
    • Description/Symptoms: Synchro wear can lead to difficulty shifting into certain gears, especially when cold. Grinding noises during gear changes are also a common symptom.
    • Solution: Rebuilding or replacing the transmission.

    • Recalls: None Found

5-Speed Automatic Transmission

  • Delayed or Harsh Shifting
    • Description/Symptoms: The automatic transmission can experience delayed or harsh shifting, especially as the car ages. This can be caused by worn valve bodies, low fluid levels, or internal component failure.
    • Solution: Servicing the transmission, including fluid and filter replacement. In more severe cases, valve body replacement or a complete transmission rebuild may be necessary.
    • Estimated Cost to Fix: $300 - $4000+ (depending on the severity of the issue)
