What is The Role of Plastic Guide Rails?
These components are part of the timing system in the engine and are made of plastic material. They assist in controlling the timing chain to make it move in the right manner and maintain the right tension. This component is especially important because it ensures that the engine’s valves and pistons are in the correct time phase. As you use your Mercedes, these plastic parts may get damaged or crack.
Expert Solutions For Plastic Guide Rail Failures
- Regular Inspections: It is always better to prevent something, than to have to treat it. The timing chain and guide rails should be checked often in order to identify any problems before they worsen. When you are having your car serviced or when the mechanic is performing a check on your Mercedes, tell him/her to check the state of the guide rails. This way you can detect damages that may be in the initial stages and prevent their progress to more complex levels.
- Timely Replacement: Your mechanic may point out during one of your routine checks, that the plastic guide rails are worn. In this case, it is recommended that they be replaced to avoid the situation getting worse. Replacing the guide rails is a pretty complex job that demands the removal of the timing chain cover, which is why this should be done by a professional. It should be noted that timely intervention helps to prevent serious damage to the engine and expensive repairs.
- Use Quality Parts: On pulling out the guide rails, make sure you are using quality parts when replacing them. Aftermarket products may be cheaper, but OEM products are made specifically for your Mercedes and are more durable and reliable. The use of OEM parts ensures that the replacements fit perfectly, have the intended functionality, and are less likely to fail in the future.
- Upgrade to Metal Guide Rails: Sometimes, you can use metal guide rails as a better solution to the problem, as it is more durable compared to plastic. Metal guide rails have less tendency of breaking or getting damaged and they last longer. However, this may not be possible for all models, so it is recommended that you consult an expert mechanic. If your model is compatible with this upgrade, then it is a good investment to have for the longevity of your engine.
- Regular Oil Changes: It is important to ensure that your engine is always supplied with fresh oil because it helps to minimize the wearing of the plastic rails. Regular oil changes also ensure that the timing chain and guide rails are adequately lubricated to prevent overheating and cracking. You should follow your Mercedes-Benz maintenance schedule for oil changes to maximize the engine performance and durability.
