It’s not common but it’s more common than people think.
Bore scoring is a problem that can occur in Porsche engines when the cylinders are over-cooled.
The scoring occurs as a result of the piston rings and cylinder wall coming into contact with each other and it can cause significant damage to the engine.
While bore scoring is not a common problem it’s more common than people think and it can be difficult to repair.
If you’re concerned about bore scoring it’s important to have your engine inspected by a qualified mechanic.
What is Porsche bore scoring?
Porsche bore scoring is a defect that can occur in the cylinders of Porsche engines.
It happens when the metal of the cylinder wears down causing scoring (or lines) to form on the inside of the cylinder.
The scoring can cause problems with engine performance and may eventually lead to engine failure.
There are several things that can cause Porsche bore scoring including incorrect engine maintenance using the wrong type of fuel or using poor-quality oil.
In some cases it may be unavoidable and simply a result of normal engine wear and tear.
However there are steps you can take to help reduce the risk of bore scoring including following the manufacturer’s recommended maintenance schedule and using high-quality oil.
Which Porsche models suffer from bore scoring?
The 996 and 997 Porsche models suffer from bore scoring. Bore scoring is a problem that is commonly caused by oil that is not up to the job.
It can also be caused by coolant leaking into the engine oil or by parts of the engine wearing down and leaving metal particles in the oil.
If your Porsche suffers from bore scoring it’s likely that you will notice a loss of power and increased fuel consumption.
You may also hear a knocking noise coming from the engine.
If you think your Porsche may be suffering from bore scoring take it to a qualified mechanic as soon as possible for a diagnosis.
How do you stop Porsche bore score?
Porsche bore score is a common problem among drivers of high-performance vehicles.

Follow the manufacturer’s recommended maintenance schedule use high-quality oil and avoid driving your car under extreme conditions.
If you’re already experiencing problems with Porsche bore scoring take your car in for repairs as soon as possible.
What causes engine cylinder scoring?
The most common cause of engine cylinder scoring is a lack of oil.
When the cylinders don’t get lubricated they can start to wear down and score.
Other causes of scoring can include:
- Engine knock or pinging which can cause premature detonation and excessive wear on the cylinders
- Glazed piston rings which can lead to increased friction and heat in the cylinders
- Excessive carbon build-up which can create a ” barrier” between the piston and cylinder wall preventing proper lubrication.
