What It Helps Address

• Low compression caused by worn piston rings
• Excessive oil consumption from poor ring sealing
• Blow-by in aging high-mileage or rebuilt engines
• Loss of cylinder pressure during classic engine restoration
• Ring wear in standard-bore vintage V8 rebuilds

Installation Notes and Tips

Confirm engine displacement, bore size, and ring groove dimensions before installation. Because this set is not file fit, verify that the standard-size specification matches the cylinder bore and piston requirements for your rebuild. Proper cylinder wall preparation, ring end-gap verification, and clean assembly practices are important for achieving correct sealing on Buick, Chevrolet, and Pontiac applications.

Quality Assurance

Sealed Power Vintage components are produced for older applications with manufacturing controls aligned to ISO and QS certified processes. The E-289K is intended for restoration and rebuild work where dependable materials and consistent fitment are important.
