Common WRX Engine Problems
The WRX, a popular sports car under the Subaru brand, is known for its powerful engine and impressive performance. But are WRX engines reliable? Despite being a popular choice among car enthusiasts, there have been some common engine problems that WRX owners have experienced over the years. In this article, we will discuss the top three common WRX engine problems that you should be aware of.
Subsection 1: Oil Pick Up Tube
- One of the most common WRX engine problems is related to the oil pick up tube. The oil pick up tube is responsible for supplying oil to the engine’s oil pump. However, due to a design flaw in older models, the tube can crack or break, causing oil starvation and engine failure.
- If you own a WRX, it is important to keep an eye on your oil levels and have your oil pick up tube inspected. You may also want to consider upgrading to a sturdier aftermarket pick up tube to avoid this issue.
- This problem has been addressed in newer WRX models, so if you’re considering purchasing one, be sure to do your research and choose a model with an updated oil pick up tube design.
Subsection 2: Head Gasket Failure
- Another common problem WRX owners have experienced is head gasket failure. The head gasket is a critical component that seals the cylinder head to the engine block. When it fails, it can result in oil leaks, overheating, and engine damage.
- This issue is more prevalent in older model WRXs, particularly those manufactured between 2002 and 2005. If you own a WRX from this period, it is important to have your head gasket inspected as part of your regular maintenance routine.
- Subaru has since addressed this issue in newer models by using a multi-layer steel head gasket that is more reliable and less prone to failure.
Subsection 3: Ringland Failure
Ringland failure is another common WRX engine problem that has been reported by many owners. The ringland is a small groove machined into the piston that holds the piston rings in place. When the ringland fails, it can cause the piston rings to lose their seal, leading to compression loss and engine failure.
This issue is often caused by heavy modifications or aggressive driving, which can put stress on the engine and cause the ringland to crack or break. To avoid this problem, it is important to maintain your engine properly and avoid harsh driving conditions. It is also recommended to upgrade to stronger pistons and connecting rods if you plan on making significant modifications to your WRX.
| Causes of Ringland Failure | Symptoms of Ringland Failure |
|---|---|
| High-boost levels | Knocking sound from the engine |
| Aggressive driving | Loss of power |
| Heavy modifications | Inability to accelerate |
If you notice any symptoms of ringland failure, such as loss of power or unusual engine noises, it is important to have your engine inspected by a professional as soon as possible to avoid further damage.
How to maintain WRX engine health
Subaru WRX engines are known for their performance and power delivery. However, they require regular maintenance to keep them running optimally. Here are some tips on how to maintain your WRX engine health:
