1950-1979 Case Sealing Washer for Case Studs 113101125 - OEM Number(s) (113-101-125)

Prevent oil seepage and keep your engine sealed with correct-fit case sealing washers.

During engine rebuilds, these small but essential washers are often lost or overlooked. Volkswagen began using these sealing washers on 1500cc engines in Buses and Type 3s to address minor leaks at the crankcase studs, but they are correct for use across all 1300cc–1600cc VW engines. Designed for use with stock plain nuts (not case-sealing nuts), they provide the reliable seal your engine needs to prevent seepage and maintain proper crankcase integrity. Six are required per engine.
