Fits: Porsche 911 2.0L
Ring Size: 1.5 x 1.5 x 3.0
Number of CYL's: 6

This is the replacement ring set for Retro Performance 81mm (00891181PJE) and 82.5mm (00891182PJE) Kits.

Piston rings perform several critical functions within an internal combustion engine. The compression rings help contain combustion pressure above the piston, reducing the amount of combustion gas that escapes into the crankcase. The oil-control rings regulate the lubricating oil film on the cylinder walls, removing excess oil while retaining sufficient lubrication for smooth piston movement. The rings also help transfer heat from the pistons into the cylinder walls.  

What This Product Does:

• Creates an effective seal between the pistons and cylinder walls.
• Helps retain combustion pressure within each cylinder.
• Supports strong and consistent engine compression.
• Reduces combustion gas leakage into the crankcase.
• Helps minimise excessive engine blow-by.
• Controls the lubricating oil film on the cylinder walls.
• Helps prevent excessive engine oil from entering the combustion chambers.
• Assists with transferring piston heat into the cylinder walls.
• Supports efficient combustion and dependable engine performance.
• Replaces worn, damaged, broken, seized, or sticking piston rings.
• Provides an OE-style replacement for compatible engine rebuilds.

Symptoms Of Wear Or Failure:

• Low or uneven cylinder compression.
• Excessive engine oil consumption.
• Blue or blue-grey smoke from the exhaust.
• Excessive crankcase pressure or blow-by.
• Reduced engine power or poor acceleration.
• Increased exhaust emissions.
• Oil-fouled spark plugs.
• Carbon deposits within the combustion chambers.
• Poor compression or leak-down test results.
• Excessive oil entering the combustion chambers.
• Broken, worn, seized, or damaged rings discovered during engine disassembly.
• Excessive cylinder bore or piston ring-groove wear.

Why Replacement Matters:

• Piston rings are essential for maintaining the cylinder seal required for efficient compression and combustion. When compression rings become worn, damaged, stuck, or lose their tension, combustion gases can escape past the pistons into the crankcase. This can reduce cylinder compression, decrease engine performance, and increase crankcase blow-by.
• Worn oil-control rings can allow excessive lubricating oil to enter the combustion chambers. This may result in increased oil consumption, blue exhaust smoke, spark plug fouling, carbon deposits, and increased emissions. Continued operation with poor ring sealing can also accelerate wear of the pistons, cylinder walls, and other internal engine components.
• Correct ring selection and installation are particularly important during an engine rebuild. Incorrect ring dimensions, excessive or insufficient ring end gaps, worn piston grooves, or an unsuitable cylinder surface finish can prevent the new rings from sealing correctly. Insufficient ring end clearance may cause the ring ends to contact as operating temperatures increase, potentially resulting in ring breakage, piston damage, or cylinder scoring.
• Replacing worn or damaged components with the correct OE Match Piston Ring Set – 00891181R or 00891182R helps restore cylinder sealing, compression, oil control, and dependable engine performance when installed as part of a correctly measured and prepared engine rebuild.

This can reduce cylinder compression, decrease engine performance, and increase crankcase blow-by.
• Worn oil-control rings can allow excessive lubricating oil to enter the combustion chambers. This may result in increased oil consumption, blue exhaust smoke, spark plug fouling, carbon deposits, and increased emissions. Continued operation with poor ring sealing can also accelerate wear of the pistons, cylinder walls, and other internal engine components.
• Correct sizing and compatibility are particularly important when installing replacement rings. The 86mm specification must match the intended pistons and cylinder bores, while ring thickness and groove dimensions must also be correct for the piston design. Incorrect ring dimensions, excessive or insufficient end gaps, or an unsuitable cylinder surface finish can prevent proper sealing and potentially cause premature wear or engine damage.

Ring size: 2.0 x 2.0 x 5.0
Number of CYL's: 4

Piston rings perform several critical functions inside the engine. The compression rings help contain combustion pressure above the piston, minimising the amount of combustion gas that escapes into the crankcase. The oil-control rings regulate the lubricating oil film on the cylinder walls, removing excess oil while retaining sufficient lubrication for smooth piston movement. The rings also assist with transferring heat from the piston into the cylinder wall.

What This Product Does:

• Creates an effective seal between the pistons and cylinder walls.
• Helps retain combustion pressure within each cylinder.
• Supports strong and consistent engine compression.
• Reduces combustion gas leakage into the crankcase.
• Helps minimise excessive engine blow-by.
• Controls the lubricating oil film on the cylinder walls.
• Helps prevent excessive oil entering the combustion chambers.
• Assists with transferring piston heat into the cylinder walls.
• Supports efficient combustion and dependable engine performance.
• Replaces worn, damaged, broken, or sticking piston rings.

Symptoms Of Wear Or Failure:

• Low or uneven cylinder compression.
• Excessive engine oil consumption.
• Blue or blue-grey smoke from the exhaust.
• Excessive crankcase pressure or blow-by.
• Reduced engine power or poor acceleration.
• Increased exhaust emissions.
• Oil-fouled spark plugs.
• Carbon deposits within the combustion chambers.
• Poor compression or leak-down test results.
• Oil contamination within the combustion chambers.
• Broken, worn, seized, or damaged rings discovered during engine disassembly.
• Excessive cylinder or piston ring-groove wear.

Why Replacement Matters:

• Piston rings are essential for maintaining the cylinder seal required for efficient compression and combustion. When the rings become worn, damaged, stuck, or lose their tension, combustion gases can escape past the pistons into the crankcase. This reduces cylinder sealing and can contribute to lower compression, reduced engine performance, and excessive blow-by.
• Worn oil-control rings can allow excessive lubricating oil to enter the combustion chambers. This may result in increased oil consumption, blue exhaust smoke, spark plug fouling, carbon deposits, and increased emissions. Continued operation with poor ring sealing can also contribute to accelerated piston and cylinder wear.
• Correct installation is particularly important when fitting new piston rings. Incorrect ring end gaps, damaged piston grooves, unsuitable cylinder surface finish, or fitting new rings into excessively worn cylinders can prevent the rings from bedding and sealing correctly, potentially resulting in premature wear or continued compression and oil-control problems.
• Replacing worn or damaged components with this OE Match Piston Ring Set VW9300T4R helps restore cylinder sealing, compression, oil control, and dependable engine performance when installed as part of a correctly measured and prepared engine rebuild.

Piston rings perform several essential functions inside the engine. The compression rings help contain combustion pressure above the piston, reducing the amount of combustion gas that escapes into the crankcase. The oil-control rings regulate the lubricating oil film on the cylinder walls, removing excess oil while retaining sufficient lubrication for piston and cylinder operation. The rings also help transfer heat from the pistons into the cylinder walls.

What This Product Does:

• Creates a seal between the pistons and cylinder walls.
• Helps retain combustion pressure within the cylinders.
• Supports strong and consistent engine compression.
• Reduces combustion gas leakage into the crankcase.
• Controls the amount of lubricating oil remaining on the cylinder walls.
• Helps prevent excessive engine oil entering the combustion chambers.
• Assists with transferring piston heat into the cylinder walls.
• Supports efficient combustion and dependable engine performance.
• Replaces worn, damaged, broken, or sticking piston rings.
• Provides an OE-style replacement for compatible engine rebuilds.

Symptoms Of Wear Or Failure:

• Low or uneven cylinder compression.
• Excessive engine oil consumption.
• Blue or blue-grey smoke from the exhaust.
• Excessive crankcase pressure or blow-by.
• Reduced engine power or poor acceleration.
• Increased exhaust emissions.
• Oil-fouled spark plugs.
• Difficulty maintaining consistent engine performance.
• Poor compression or leak-down test results.
• Carbon deposits caused by excessive oil entering the combustion chamber.
• Broken, worn, seized, or damaged rings discovered during engine disassembly.
• Excessive cylinder or piston ring-groove wear.

Why Replacement Matters:

• Piston rings are essential for maintaining the seal required for efficient engine combustion. When the rings become worn, damaged, stuck, or lose their tension, combustion gases can escape past the pistons into the crankcase. This loss of sealing can reduce cylinder compression, decrease engine performance, and increase blow-by.
• Worn oil-control rings can also allow excessive lubricating oil into the combustion chambers. This may lead to increased oil consumption, blue exhaust smoke, spark plug fouling, carbon deposits, and increased emissions. Continued operation with poor ring sealing can contribute to further cylinder and piston wear.
• Correct installation is particularly important when replacing piston rings. Incorrect ring end gaps, damaged ring grooves, unsuitable cylinder surface finish, or installation into excessively worn cylinders can prevent new rings from sealing correctly and may cause premature failure.
