The 4975214 rocker lever housing gasket fits Cummins ISZ, QSZ Z13 and ISX12 diesel engines perfectly. It creates a tight seal on valve train assemblies to stop oil seepage and dust intrusion. Resistant to high engine temperature and lubricant erosion, it protects internal rocker components from premature wear. Easy to mount during cylinder head disassembly for engine repair shops.
