What is the timing chain problem with Subaru?

Timing Chain Problem with Subaru
Subaru vehicles have used both timing belts and timing chains in their engines. While most of the very latest Subaru models feature a permanent metal timing chain, older Subaru models and the ultra-high-performance Subaru WRX STI feature a rubberized timing belt. It’s important to note that modern Subaru engines are interference engines, meaning that a broken timing belt could cause severe damage to the engine. Therefore, it’s crucial to get the timing belt on older Subaru models changed before it fails. On the other hand, Subaru models from the 2014 model year or newer are equipped with a timing chain that doesn’t need regular maintenance.
In 2011, Subaru moved to a timing chain, which they referred to as a lifetime component. This change was made to address the issues associated with timing belt failure, which has historically been a significant concern for Subaru and other car owners. The timing chain is designed to be a more durable and maintenance-free alternative to the timing belt.
Symptoms of a Bad Timing Chain
– Engine Misfiring: If the engine timing system is slightly off, it can result in engine misfiring.
– Rattling Sound: A lax or broken timing chain can produce a rattling sound when the car is idling, which can indicate a problem with the timing chain.
– Metal Shavings in Oil: As a timing chain wears out, it may disintegrate, leading to metal shavings that can end up in the car’s oil pan.
Importance of Timing Chain Maintenance
It’s crucial to be aware of the type of timing system in your Subaru and to follow the recommended maintenance schedule. Whether it’s a belt or a chain, the timing system is critical to the functioning of the vehicle’s engine. If the system fails, it can lead to catastrophic destruction of the engine. Therefore, it’s necessary to get the timing belt changed at the recommended interval if the vehicle is equipped with a timing belt. For vehicles with a timing chain, it’s important to be aware of any symptoms of a bad timing chain and to address them promptly to prevent potential engine damage.
Conclusion
In summary, the timing chain problem with Subaru primarily relates to the potential issues associated with timing belt failure in older models and the shift to a more durable and maintenance-free timing chain in newer models. It’s important for Subaru owners to be aware of the type of timing system in their vehicles and to address any symptoms of a bad timing chain promptly to prevent potential engine damage.

What years did Subaru have CVT transmission problems?

Subaru owners have complained about problems with the Lineartronic CVT transmissions and Subaru extended the warranty for cars from model years 2010 to 2018. Usage: 2010–current Subaru Legacy / Outback / Exiga / Impreza / Levorg / Forester / XV and 2015 Subaru WRX Premium and Limited Editions.

Do Subarus have timing chain issues?

All Subaru sold in the USA after 2005 have an “Interference” engine. Therefore, if the timing belt or timing chain breaks or jumps timing, it can cause bent valves and possibly dinged pistons in the engine, thus resulting in expensive repairs. If you have an older car, some model were Interference and others not.

At what mileage should a timing chain be replaced?

Unless there is a specific fault, the timing chain should be replaced between 80,000 and 120,000 miles. Chain problems are frequent in automobiles with increasing mileage. If you’re driving an older car or one with a lot of miles on it, keep an eye out for signs that the timing chain is failing.

Is replacing a timing chain a big job?

Timing chain installation requires the right tools, a service manual specific to the engine’s model and a degree of mechanical know-how. Because it is a major job, the risk of performing it incorrectly could trigger irreversible consequences for the engine.

Is there a warning before a timing chain breaks?

There are three major signs of a bad timing chain: Rattling or clattering noises coming from the engine. The check engine light is on. The engine repeatedly misfires.

What year did Subaru use timing chain?

When it comes to Subarus, timing chains are standard on practically all models produced since 2013. The Subaru WRX and Subaru WRX STI are the exceptions.

Can a timing chain last 300000 miles?

A timing chain should easily last the life of the engine, well over 100,000 miles even upward of 250K, other parts will wear out or fail first.

Which Subarus have timing chains?

Simply, then, a 1997 to 2011 Forester will have a timing belt, while any of the fourth-gen Foresters (from 2013 or later) will have a timing chain. And for a brief period from 2011 to 2012, the Forester was fitted with either a timing belt or a timing chain depending on which engine was fitted.

How long does a Subaru timing chain last?

A timing chain is bulkier and louder; however, it does not require replacement. Though a repair might be necessary in some rare occasions, most timing chains last for the entire life of the engine.

What are the symptoms of a worn out timing chain?

Misfiring, poor idle, and rough running could mean the chain has jumped a tooth and the timing is off. Replacement is urgent, because the chain could break at any point, and the engine could be damaged from incorrect valve timing. Metal shavings or visible pieces of chain in the oil would be another potential sign.
