06A-198-151C Piston Ring Set Standard 1x1.5x2 82.50mm - Audi A4 A6 VW Passat

Piston Ring Set (Standard 82.50mm) – 06A-198-151C

The 06A-198-151C is a high-quality standard-size piston ring set designed for a wide range of Audi and Volkswagen engines, specifically the 2.8L V6 and 2.0L 4-cylinder powerplants. This set includes the compression and oil control rings required for a single piston. These rings are essential for maintaining engine compression, preventing oil from entering the combustion chamber, and ensuring efficient heat transfer from the piston to the cylinder wall.

If you are experiencing blue exhaust smoke, high oil consumption, or a loss of engine power, worn piston rings are a likely culprit. This part is a direct replacement for older part numbers 078-198-151 and 078-198-151-A. For a complete engine rebuild, ensure you order one set for each cylinder (e.g., six sets for a V6 engine).

Installation & Maintenance Tips

• Cylinder Honing: For the best ring seat, cylinders should be lightly honed to create a "cross-hatch" pattern before installing new rings.

• Ring Gap Measurement: Always "dry fit" the rings into the cylinder bore and measure the end gap with a feeler gauge to ensure they meet the engine's factory tolerances.

• Proper Orientation: Pay close attention to the "Top" markings on the rings; installing a compression ring upside down will lead to immediate oil consumption and poor performance.
