A faulty timing belt can spell lots of trouble for your Porsche (and for your budget too). It gets even worse where the timing belt breaks. That’s why it is important to know not just the warning signs of a worn out timing belt but also what it does. That way, you will understand how it impacts the vehicle’s engine performance.

Timing belts are mostly made of rubber. They are then reinforced with special nylon cords to ensure they are extra strong. This makes it easy for the belts to rotate the crankshaft and the cam so that all the engine cylinders fire at the same time. Note that the engine also relies on pistons and valves which should sync perfectly with the cylinders. If this does not happen, the engine won’t run at all. Unfortunately, checking on timing belts is not easy because they are mostly sealed in their own cover. The cover protects the belt from dirt and oil that circulate around the engine. This is exactly why timing belt inspection and repairs should be done by a Porsche expert.
Older Porsche models used rubber timing belts. This is not the case anymore with new Porsche models. They now use metal timing chains which are durable and easy to maintain. Refer to your car’s manual to be sure whether your model uses a timing belt or a modern timing chain.
Why They Fail
Timing belts fail because of two main reasons. The first reason, which is age is hard to prevent because with time, wear and tear becomes inevitable for many car components that depend on friction to function. The second reason, which is water pump failure, is easy to prevent as you only need to budget for scheduled maintenance. The timing belt can also begin to get brittle. It will then crack and eventually snap. This won’t happen though without the following warning signs.
Rough Engine Running
Your Porsche’s engine running is directly connected to the timing belt. That is why it is not uncommon for the engine to suddenly misfire if the belt malfunctions. The engine might also have unpredictable performance because of a worn or loose timing belt. Such a performance means the belt is slipping and leaving the engine cylinders close and open at the wrong time.
There are so many reasons why starters sometimes malfunction. One such reason has everything to do with a broken timing belt. As a matter of fact, your car won’t start at all once the timing belt breaks. It is actually important to avoid trying to start the car over and over again if you suspect the timing belt is broken. That way, you will avoid damaging the cylinder heads, the water pump and the bearings.
Clicking Noise From The Engine
This happens because of low oil pressure. The low pressure affects the timing belt which in turn affects the crankshaft and the cams. There is no quick fix solution here other than to have your mechanic fix the problem immediately.
