Detailed Description

Melling CSL103 cylinder liners are made for engine rebuild work where a worn sleeve must be replaced with a correctly sized liner. The cast iron construction and standard replacement grade make this part suitable for stock engine service, while the universal, non-flanged design supports a wide range of block repair applications. This part cross-references LA45 and ML103 for the same application.

Common Repair Uses

• Restoring a worn cylinder sleeve during an engine rebuild
• Correcting cylinder wall damage from scoring or wear
• Replacing a sleeve that no longer holds proper bore dimensions
• Repairing an engine block that needs standard replacement service
• Supporting stock rebuild work on Chevrolet, GMC, Oldsmobile, and Pontiac applications

Installation Notes

Verify bore dimensions and liner specifications before installation. This liner is universal and non-flanged, so final machine work and fitment checks should be completed during the rebuild process. Match the liner to the engine block requirements and confirm the listed dimensions against the application before assembly.

Quality Assurance

Melling positions this liner within its stock replacement line and manufactures cylinder liners with quality materials and workmanship for engine rebuild service.
