What It Helps Address

• Low compression from worn or damaged piston rings
• Excessive oil consumption caused by poor oil control
• Blow-by from weakened cylinder sealing
• Smoke from ring wear or stuck oil control rings
• Engine rebuild needs on 86.00 mm bore 4-cylinder platforms

Installation Notes and Tips

Verify bore size, groove widths, and piston specifications before assembly. Because this set is not file fit, ring end gaps should be checked against the engine builder’s specifications rather than trimmed during installation. Clean ring lands thoroughly, confirm ring orientation, and inspect cylinder wall condition before final assembly. For best results, match the rings to the exact engine code and application listed for your Buick Regal, Chevrolet Malibu, or Saab 9-3 build.

Quality Assurance

Sealed Power manufactures engine components with leading-edge materials and controlled production processes to support consistent fit and performance in modern engines. E-971K is built as a standard-size replacement ring set for the listed applications.
