BCBC K-20I Engine Oil Pump Repair Kit

Engine Oil Pump Repair Kit Overview

Melling K-20I is an engine oil pump repair kit for specific applications that need a rebuild rather than a full pump replacement. It is built around powdered metal drive gear construction, an 8-tooth drive gear, and a fiber gasket to support a precise oil pump rebuild.

Key Features

• Specific-fit oil pump repair kit for targeted applications
• Powdered metal drive gear for rebuild service
• 8-tooth drive gear configuration
• Fiber gasket material with 6 mounting holes
• Used when reusing the original oil pump casting or front timing cover

Detailed Description

Melling K-20I is intended for rebuilding a specific individual oil pump when the original casting or front timing cover is being retained. Melling notes that a new oil pump is the preferred service choice, but this kit provides the parts needed for a quality rebuild when the existing pump assembly is being serviced. The K-20I part number is associated with a wide range of classic GM and Jeep applications, including Buick, Chevrolet, Oldsmobile, Pontiac, and Jeep models. For buyers searching for an engine oil pump repair kit for Buick Regal, Pontiac Firebird, or Jeep CJ5 applications, K-20I is a direct rebuild-focused option.

This part cross-references Sealed Power 224-518 and Walker Exhaust 51108 for the same application.

What It Is Used For

• Restoring oil pump function during engine rebuild work
• Replacing worn internal pump components without changing the casting
• Addressing low oil pressure caused by pump wear
• Servicing original front timing cover oil pump assemblies
• Supporting rebuilds on classic Buick, Pontiac, Chevrolet, Oldsmobile, and Jeep engines

Installation Notes and Tips

Confirm the application before ordering, since K-20I is a specific-fit kit and some listed vehicles note that the P-20I thrust plate kit is not included. Clean the pump housing thoroughly before assembly and inspect the original casting or front timing cover for wear, scoring, or damage. Follow the engine builder’s service procedures and verify gear clearance and gasket placement during installation.

Quality Assurance

Melling supplies this kit as a rebuild parts package for a specific oil pump application. The brand recommends a new oil pump when replacement is the preferred service path, while this kit serves rebuilders who want to reuse the original pump casting or front timing cover.
