Fits:

The cylinder kit forms the combustion chamber walls in conjunction with the pistons and piston rings, providing the sealed environment required for efficient compression and combustion. Over time, continuous piston movement, heat cycles, and normal engine wear can cause the cylinder bores to become worn, tapered, scored, or out of round. Replacing worn cylinders restores engine compression, improves oil control, and helps return the engine to smooth, efficient operation.  

What This Product Does:

• Provides precision-machined cylinder bores for the pistons.
• Restores engine compression and combustion efficiency.
• Supports correct piston and piston ring operation.
• Improves oil control and reduces blow-by.
• Dissipates engine heat effectively.
• Replaces worn, scored, or damaged cylinders.
• Provides an OE-style fit for straightforward engine rebuilding.

Symptoms Of Wear Or Failure:

• Low engine compression.
• Excessive oil consumption.
• Blue exhaust smoke caused by oil burning.
• Loss of engine power or performance.
• Excessive crankcase blow-by.
• Scored, worn, or tapered cylinder bores.
• Piston slap or excessive engine noise.
• Damage identified during engine overhaul.

Why Replacement Matters:

• The cylinders are fundamental to engine performance, providing the precision sealing surfaces required for efficient combustion and reliable piston movement. As cylinder bores wear, compression is reduced, oil consumption increases, and engine performance deteriorates. Continued operation with worn cylinders can accelerate wear of pistons, rings, and other internal engine components.
• Replacing worn cylinders with this OE Match 80mm Cylinder Kit restores compression, improves engine efficiency, reduces oil consumption, and supports long-term engine reliability. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Cylinder Kit provides reliable fit, performance, and durability for classic Volkswagen and compatible Porsche engine maintenance, repairs, and restoration projects.

• Pistons are among the most highly loaded components inside an engine and play a fundamental role in compression, combustion, and power production. Excessive piston skirt wear, damaged ring lands, worn pin bores, cracked crowns, or incorrect running clearances can compromise cylinder sealing and piston stability.
• Worn or damaged pistons may lead to reduced compression, increased oil consumption, excessive blow-by, poor engine performance, abnormal internal noise, and accelerated wear of the cylinders and other engine components. Severe piston damage can ultimately lead to extensive internal engine failure.
• Correct piston and pin compatibility is also essential during an engine rebuild. The 80mm piston diameter and 22mm piston pin must be correctly matched to the cylinders, connecting rods, and overall engine specification.
