When it comes to keeping your Subaru running smoothly, the timing belt is a critical component. This small yet vital part is responsible for synchronizing your engine’s camshaft and crankshaft, ensuring your engine’s valves open and close at the precise intervals needed for optimal performance. For Subaru owners in Orange County and South County, CA, Rallysport Engineering is the go-to specialist for timing belt replacements. With over 40 years of expertise, Rallysport Engineering offers trusted, high-quality timing belt replacement and other auto services in Costa Mesa.
What is a Timing Belt, and Why is it Important?
In your Subaru’s engine, the timing belt is a reinforced rubber belt that synchronizes the rotation of the crankshaft and camshaft. This synchronization allows the engine’s valves to open and close in coordination with the engine’s pistons, ensuring proper combustion. If the timing belt breaks or becomes misaligned, the engine may experience severe damage, potentially leading to costly repairs or even total engine failure. Regular replacement of your timing belt is critical for maintaining your vehicle’s performance and preventing unexpected breakdowns.
Subaru owners must prioritize timing belt maintenance as these engines, especially older models, are known for interference designs, where a failed timing belt can lead to serious internal engine damage. Rallysport Engineering specializes in Subaru engines and understands the intricacies of these systems, making them the ideal choice for timing belt replacement.
Signs Your Subaru’s Timing Belt Needs Replacement
Subaru vehicles typically require timing belt replacements every 60,000 to 100,000 miles, depending on the model and year. However, mileage isn’t the only indicator of a timing belt needing replacement. Here are some common warning signs that your timing belt may be nearing the end of its life:
- Engine Misfires
A worn or misaligned timing belt may cause the engine to misfire, which can damage the engine over time. - Ticking Noise from the Engine
If you hear a ticking sound coming from the engine, it could be the timing belt starting to wear out. - Difficulty Starting the Engine
A worn timing belt can cause problems with starting the engine and may result in stalling. - Oil Leaks
If you notice oil leaking from the front of your engine, it may be a sign that the timing belt cover gasket has become loose, a common issue when the timing belt is aging. - Engine Vibrations
As the belt wears, it may cause the engine to vibrate, reducing the smoothness of your ride and potentially leading to larger engine issues.
The Timing Belt Replacement Process at Rallysport Engineering
Replacing a timing belt requires a skilled hand and a deep understanding of the engine’s mechanics. Here’s what you can expect from a timing belt replacement service at Rallysport Engineering:
- Initial Inspection
Before beginning any work, the technicians at Rallysport Engineering will perform a thorough inspection to verify the timing belt’s condition and check for any additional components that might need attention, such as the water pump or pulleys. - Removal of Old Timing Belt
The old timing belt is carefully removed. This process involves disassembling certain parts of the engine and requires meticulous attention to detail to ensure nothing is damaged or misplaced. - Replacement of Related Components
Rallysport Engineering’s technicians don’t just replace the belt itself; they inspect and replace other related components if necessary. Parts like tensioners, idlers, and water pumps are often replaced alongside the timing belt to ensure everything operates smoothly. - Installation of New Timing Belt
A high-quality, Subaru-compatible timing belt is installed, aligning the camshaft and crankshaft with precision. - Final Inspection and Testing
After installation, the technicians perform a final inspection and test to ensure the timing belt is correctly aligned and that the engine operates as expected.

The Risks of Postponing Timing Belt Replacement
Delaying timing belt replacement can lead to serious engine damage, especially in Subaru’s interference engines, where a timing belt failure can result in valve and piston collision. Ignoring timing belt replacement can lead to:
- Complete Engine Failure
A failed timing belt can cause catastrophic engine damage, potentially leading to the need for a full engine rebuild or replacement. - Costly Repairs
Replacing the timing belt before it fails is far more affordable than repairing engine damage caused by a broken belt. - Reduced Vehicle Performance
A worn timing belt affects engine timing, leading to poor fuel efficiency, rough idling, and reduced power.
