Sealed Power E-936K Engine Piston Ring Set

Sealed Power E-936K Piston Ring Set

Sealed Power E-936K is an engine piston ring set built for 93.00 mm bore applications with standard sizing and OE-style groove widths. It uses a steel top ring with moly face, a grey iron second ring, and a 3-piece Flex Vent oil ring design for precise cylinder sealing in V8 engines.

Compatible with 1996-1999 Cadillac DeVille, Cadillac Eldorado, and Cadillac Seville applications, this ring set matches the listed 1.2 mm top ring, 1.5 mm second ring, and 3.0 mm oil ring groove widths. The E-936K part number is also referenced against MAHLE 41862CP and 12555217 for the same application.

Key Features

• 93.00 mm bore diameter and outside diameter
• Standard size ring set for listed applications
• Top ring material: steel with moly face
• Second ring material: grey iron with reverse torsional face design
• 3-piece Flex Vent oil ring design
• Ring groove widths: 1.2 x 1.5 x 3.0 mm
• Built for 8-cylinder engine applications

Detailed Description

Sealed Power E-936K piston rings are engineered for engines that require a 93.00 mm bore and standard ring dimensions. The barrel-face top ring, reverse torsional second ring, and 3-piece Flex Vent oil ring work together to support cylinder sealing, oil control, and consistent compression in the engine block. For 1996-1999 Cadillac DeVille, Eldorado, and Seville models, the E-936K provides the specified groove-width match needed for proper ring fitment.

Sealed Power uses modern materials and ISO- and QS-certified manufacturing practices to produce engine components that meet demanding service requirements. If you are rebuilding a Cadillac DeVille, Cadillac Eldorado, or Cadillac Seville engine from the listed years, E-936K is a direct-fit piston ring set for the confirmed bore and groove specifications.

Common Issues This Part Can Address

• Low compression from worn piston rings
• Excessive oil consumption caused by ring wear
• Blow-by from poor cylinder sealing
• Loss of ring tension in high-mileage engines
• Uneven sealing after engine rebuild work

Installation Notes and Tips

Verify bore diameter, ring groove widths, and cylinder condition before installation. Measure each cylinder and confirm the 1.2 mm, 1.5 mm, and 3.0 mm groove stack matches the engine specification. Clean ring lands thoroughly, check end gaps to specification, and follow the engine builder’s installation procedure for ring orientation and break-in.

Because this is a standard-size piston ring set, confirm that the engine has not been overbored or previously machined beyond the listed 93.00 mm specification. Use proper cylinder honing and assembly practices to help the rings seat correctly.

Quality Assurance

Sealed Power manufactures engine components using leading-edge materials and certified production processes to support consistent fit and performance. The E-936K part number is backed by Sealed Power’s established engine parts engineering and is cross-referenced to MAHLE 41862CP and 12555217 for the same application.
