2869891 Valve Cover Gasket

2869891 valve cover gasket is the sealing gasket between valve cover and cylinder head on Cummins ISZ, QSZ and Z13 engines. Made of multi-layer composite sealing material, it maintains stable elasticity under temperature variation and vibration, forming tight seal to stop engine oil leakage. It resists erosion from hot oil and crankcase gas to prevent aging and compression set during long service. Its contour fully matches valve cover edge, so no trimming needed during installation. Replacing aged gasket with this part eliminates oil seepage, protects engine cleanliness and keeps ISZ, QSZ, Z13 Cummins engines in good condition.
