Engine Problems: The Heart of the Beast
The RB26DETT engine, while legendary for its performance, can present several challenges:
- Oil Leaks: Common from various gaskets and seals, particularly as the engine ages.
- Turbocharger Failures: Stock turbos can fail, especially in highly tuned engines.
- Timing Belt and Water Pump Concerns: Regular replacement is crucial to prevent catastrophic failure.
Regular maintenance is key to preventing these issues. Our timing belt replacement tutorial can be a valuable resource for this critical maintenance task.
Engine Issues Table
| Problem | Symptoms | Potential Solutions |
|---|---|---|
| Oil Leaks | Oil spots under car, burning oil smell | Replace gaskets and seals |
| Turbo Failure | Loss of power, unusual noise | Rebuild or replace turbos |
| Timing Belt Wear | Engine misfires, potential failure | Replace belt and water pump |
Fuel System Problems: Feeding the Beast
The high-performance nature of the Skyline can stress the fuel system:
- Fuel Pump Failures: Common in high-mileage or heavily modified cars.
- Injector Issues: Clogging or failure, especially with aftermarket fuels.
- Fuel Pressure Regulator Faults: Can lead to inconsistent fuel delivery.

Transmission and Drivetrain Issues: Power Delivery Challenges
The Skyline’s drivetrain, while robust, can face issues under high stress:
- Gearbox Faults: Synchro wear and bearing failures in manual transmissions.
- Clutch and Flywheel Wear: Particularly in cars with increased power output.
- Differential Problems: Wear and noise, especially in cars used for racing or drifting.
Regular fluid changes and inspections can prevent many of these issues. Consider upgrading to stronger components if increasing the car’s power output.
Electrical System Gremlins: Modern Complexities in a Classic Design
The Skyline’s electrical system can present various challenges:
- ECU Issues: Aging computers can lead to various performance problems.
- Coil Pack Failures: Common cause of misfires and poor performance.
- Sensor Malfunctions: MAF, O2, and knock sensors often need replacement.
Regular diagnostic scans can catch many electrical issues early. Our spark plug replacement guide can help address some ignition-related problems.
Electrical Issues Table
| Issue | Symptoms | Solutions |
|---|---|---|
| ECU Problems | Check engine light, erratic performance | ECU repair or replacement |
| Coil Pack Failure | Engine misfires, rough idle | Replace faulty coil packs |
| Sensor Malfunctions | Poor fuel economy, performance issues | Replace faulty sensors |
Suspension and Braking System Concerns: Keeping Control
The Skyline’s high-performance nature can take a toll on suspension and brakes:
- Suspension Wear and Alignment Issues: Bushings and ball joints often need replacement.
- Brake System Problems: Caliper seizures and rotor warping are common.
- HICAS System Faults: The four-wheel steering system can develop issues over time.
Regular inspections and timely replacements are crucial. Our brake pad replacement DIY guide can help maintain one critical aspect of the braking system.
Body and Structural Issues: Battling Time and Elements
Skylines, especially older models, are prone to rust and structural issues:
- Rust and Corrosion: Common in wheel arches, floor pans, and strut towers.
- Chassis and Subframe Problems: Rust can compromise structural integrity.
Regular inspections and prompt repair of any rust spots are essential. Consider undercoating and rust-proofing treatments for prevention.
Maintenance Tips and Prevention Strategies: Keeping Your Skyline in Top Form
To keep your Nissan Skyline running smoothly and avoid potential issues, consider the following maintenance tips:
- Regular Oil Changes: More frequent than modern cars, typically every 5,000 km or less with high-performance use.
- Timing Belt Replacement: Critical to prevent catastrophic engine failure, typically every 60,000-80,000 km.
- Turbo Inspections: Regular checks for play and oil leaks can prevent costly failures.
- Suspension and Brake Inspections: Crucial for safety and performance, inspect every 10,000-15,000 km.
- Rust Prevention: Regular underbody cleaning and inspection, especially in areas with road salt use.
Maintenance Schedule Table
| Maintenance Item | Recommended Interval | Importance |
|---|---|---|
| Oil Change | Every 5,000 km or less | Critical for engine longevity |
| Timing Belt | Every 60,000-80,000 km | Prevents catastrophic engine failure |
| Turbo Inspection | Every 20,000 km | Prevents costly turbo failures |
| Suspension Check | Every 10,000-15,000 km | Ensures handling and safety |
| Rust Inspection | Annually | Prevents structural issues |
Conclusion: Owning and Maintaining a Nissan Skyline
The Nissan Skyline, particularly the GT-R models, offers an unparalleled driving experience and a piece of automotive history. However, ownership comes with its challenges, especially as these cars age.
When considering a Skyline, it’s essential to:
- Research the specific model thoroughly, understanding its common issues
- Budget for potentially expensive repairs and maintenance
- Consider the availability of parts and qualified mechanics in your area
- Be prepared for more frequent and involved maintenance than modern cars
With proper care, attention, and preventative maintenance, a Nissan Skyline can provide years of exhilarating performance and automotive enjoyment. However, potential owners should weigh the car’s legendary status and performance capabilities against the increased maintenance needs and potential for costly repairs.
