Restore effective cylinder sealing, compression, and oil control during an engine rebuild with this OE Match Piston Ring Set, available under references 0081182R and 0081183R. Designed for compatible engine applications, these piston rings fit into the machined grooves around each piston and create the essential sealing interface between the piston and cylinder wall.
Fits: Porsche 356
Ring Size: 1.5 x 1.5 x 3.0
Number of CYL's: 4
This is the replacement ring set for Retro Performance 82.5mm (0081182PJE), (0081182JEP) and 83.5mm (0081183PJE), (008 11 83JEP) 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, 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. Worn, damaged, or sticking compression rings allow combustion gases to escape past the pistons into the crankcase, potentially causing reduced compression, decreased engine performance, and excessive blow-by.
- Worn oil-control rings can allow excessive lubricating oil into the combustion chambers. This can 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 new rings from sealing correctly. Insufficient end clearance may cause the ring ends to contact as operating temperatures increase, potentially resulting in broken rings, piston damage, or cylinder scoring.

86mm Piston Rings.
Restore effective cylinder sealing, compression, and oil control during an engine rebuild with these OE Match 86mm Piston Rings, reference 0081186R. Designed for compatible 86mm piston and cylinder applications, this piston ring set provides a high-quality replacement solution for worn, damaged, broken, or sticking rings during engine rebuilding, restoration, or repair.
Fits: Porsche 356/912
Ring Size: 2.0 x 2.0 x 2.0 x 5.0
Number of CYL's: 4
This is a replacement set for Retro Performance (0081186PS) and (0081186PB) Kits.
Piston rings sit within precisely machined grooves around each piston and create the critical sealing interface between the piston and cylinder wall. The compression rings help contain the pressure generated during combustion, while the oil-control rings regulate the lubricating oil film on the cylinder walls. The rings also assist with transferring heat away from the piston into the cylinder wall.

- Broken, worn, seized, or damaged rings found 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 result in reduced compression, loss of engine performance, and excessive blow-by.
- Worn oil-control rings can allow excessive lubricating oil to enter the combustion chambers. This may cause increased oil consumption, blue exhaust smoke, spark plug fouling, carbon deposits, and increased emissions. Continued operation with poor piston ring sealing can also accelerate wear of the pistons, cylinder walls, and other internal engine components.
- Correct sizing is particularly important when replacing piston rings. The 86mm specification must be correctly matched to the intended pistons and cylinder bores. Incorrect ring dimensions, excessive or insufficient end gaps, worn piston grooves, or an unsuitable cylinder surface finish can prevent new rings from sealing correctly and may result in premature wear or engine damage.
- Replacing worn or damaged components with these OE Match 86mm Piston Rings 0081186R helps restore cylinder sealing, compression, oil control, and dependable engine operation when installed as part of a correctly measured and prepared engine rebuild.
