Enginetech ESL181 is a centrifugally cast iron cylinder repair sleeve with 3.875 inch bore, 6.250 inch length, 3/32 inch wall, cataloged for 1957-2006 American Motors, Buick, Chevrolet and additional applications. It restores a damaged or over-bored cylinder to OE standard bore size without replacing the entire block.
Important Notes
- Sleeve is supplied with a semi-finished inside diameter; plan to remove at least 0.025 inch during final bore and hone to achieve the correct piston-to-wall clearance.
- Chamfered bottom outside diameter is intended to ease installation into the engine block; a light interference fit is typical and the block counterbore should be measured before pressing.
- Nominal wall thickness is 3/32 inch. Confirm the block counterbore diameter will accept the sleeve outside diameter before ordering.
- Sold individually; quantity required equals the number of cylinders being sleeved.
- Ships individually boxed and wrapped in rust-preventative paper.

Enginetech cylinder sleeves are centrifugally cast engine block repair components available in a full range of bore diameters and lengths, supplied in standard 3/32 inch and 1/8 inch wall thicknesses. Centrifugal casting produces homogenous material throughout each sleeve for consistent hardness and machinability, and every sleeve is supplied with a semi-finished inside diameter that allows the machinist to remove at least 0.025 inch during boring and honing for a precision bore-to-piston fit. A chamfered bottom OD edge eases installation into the block, and each sleeve ships individually boxed and wrapped in rust-preventative paper for clean shelf storage. Enginetech also produces high-performance sleeves cast from a premium formula yielding higher hardness (293 BHN) and higher tensile strength (45,000 PSI) where the application demands it. Always verify bore diameter, sleeve length, and wall thickness against the damaged cylinder before ordering.
