With proper maintenance and care, the high-performance Boxer engine of a Porsche can last 150,000 miles or more. With regular servicing trips to your local Porsche dealer, you can delay the high cost of engine replacement. But at some point, every driver needs to decide whether to replace an engine or buy an entirely new car. Keep an eye out for the following five signs that your engine might be on its last legs.
Persistent Overheating
The first time your engine overheats, it might be due to a malfunctioning cooling system. But if your cooling system is checked and repaired, and the engine keeps overheating, then your car has a more significant problem.
If you experience this, have your engine block inspected for cracks. A cracked engine block is impossible to repair, and you’ll need to have the entire engine changed out.
Persistent Power Loss
A Porsche without engine power is like candy without sweetness. No driver wants to experience a loss of power in their Porsche. If you find that your engine simply isn’t packing as much accelerating punch as it used to, no matter how many times you have it checked, then it might be time to get a new one. All you can do to delay that fateful day is maintain the engine well with regular servicing.
Persistent Knocking
The first time you hear knocking from your engine, it might be due to leaking or aging motor oil, which is failing to lubricate properly. Flushing your motor oil should fix this problem. But persistent knocking indicates rod knock, which means your engine’s rod bearings are worn down or broken. The rod bearings are the parts that pump the pistons up and down in the engine’s cylinders.
These rods are such a fundamental part of the engine that you’ll need a complete engine rebuild to replace faulty bearings and rods. And it’s rarely the rod bearings alone that are damaged. You’ll probably need to replace the crank, the pistons, and perhaps more parts as well. Depending on the age of your engine at this stage, it might make more sense to replace the whole engine.
Your Engine Seizes Up
A seized-up engine can rarely be repaired at a lower cost than the cost of an entirely new engine. When poorly maintained, various things can cause an engine to eventually seize up and stop functioning altogether.
Most commonly, complete engine failure is due to incorrect, insufficient, or seriously degraded motor oil. An engine can also seize up because of excessive rust or metal shavings inside, water in the combustion chambers, or a timing belt snapping.
A Trusted Porsche Dealer Advises You Replace Engine
You’ll most likely hear the news that your engine needs to be replaced by a professional inspecting your car. Such a warning shouldn’t be ignored as it’s very dangerous to drive with a failing engine. If you’re in doubt, you can always ask another technician for a second opinion.
