The Hidden Risks Of Plastic Guide Rail Failure in Mercedes Cars

Mercedes, the renowned German car manufacturer, has never ceased to amaze its admirers. Its research and development team works tirelessly to ensure that every vehicle that leaves its factory is fast, safe, and reliable. But no matter how well a vehicle is made, it is bound to develop defects after some time. Components made of plastic, in particular, become prone to premature wear and tear.

Today's blog post is about one such component. In this post, we have discussed everything there is to know about Mercedes’ plastic guide rail.

Importance of Mercedes’ Plastic Guide Rail

To put it in a nutshell, the plastic guide rail ensures that the timing chain does not deviate from its path. By doing so, it ensures that the cam and crankshaft rotate in unison. And, at the end of the day, that's all that matters… Since the plastic guide rail is involved in keeping the engine timing stable; if it gets damaged, the engine timing will be messed up.

And, guess what???? Messed-up engine timing can contribute to all kinds of problems related to engine performance, including mechanical failure. So, if you want your Mercedes to operate at full pace, you must look after its plastic guide rail. Listed below are some of the prominent reasons and signs of plastic guide rail failure. Please take a look…

Factors That May Contribute To Plastic Guide Rail Failure

There are several reasons why your Mercedes' plastic guide rail may fail; the most prominent being hot engine temperature. Plastic guide rail, as the name suggests, is made of plastic. The problem with making something from plastic is that it cannot tolerate extremely hot temperatures.

Some other noticeable factors that can contribute to plastic guide rail failure in a Mercedes are; engine overheating, bad driving habits, driving on rough roads, weakness in structural integrity due to aging, etc… Whatever it is, driving with a defective plastic guide rail can prove to be disastrous for your Mercedes engine.

But, don't worry… There are signs you can look for if it occurs to you that your Mercedes' plastic guide rail is acting up. Below is a detailed discussion about those signs… Please read through.

Key Indicators of Plastic Guide Rail Failure

Indicator #1- Engine shuddering

Look… it is the plastic guide rail that enables the timing chain to rotate within the specified path. If for some reason the guide rail malfunctions, the timing chain will move freely. This will result in the emergence of a shaking sensation. Engine vibration will become more pronounced when you press the accelerator. Replace the defective rail guide before things take a turn for the worse.

Indicator #2- Poor engine performance

Another key indicator that your Mercedes' plastic guide rail has failed is weak engine performance. Since the guide rail plays a crucial role in maintaining optimal engine timing; if it gets damaged, the engine timing will be messed up… this, in turn, will result in all sorts of engine performance-related flaws including sluggish performance and misfire. The issue will only get worse over time.

Indicator #3- Engine warning light

Any part that has something to do with engine operation, if malfunctions, can turn on the check engine light. And, guide rail failure is no exception… The guide rail, as we have already discussed more than once in this blog post, plays a vital role in maintaining optimal engine timing. Anything that messes with the engine timing, whether it's the guide rail or something else, will cause the check engine light to flash.

Indicator #4- Structural damage

You should check your Mercedes’ guide rail every now and then. If you notice something unusual with the guide rail like a fracture, you should be quick to take action. Because leaving such an issue unaddressed can result in irreparable engine damage.

Keeping Things Short…

Guide rail; this seemingly trivial component plays a very important role in your Mercedes engine. If for some reason it wears out, the engine will have to deal with all sorts of performance drama including sluggish performance and misfire. Therefore, we recommend that you keep an eye on your Mercedes guide rail and if you notice something strange about it, contact a certified professional.
