Caterpillar 119-2940 Valve Cover Gasket

The Caterpillar 119-2940 Valve Cover Gasket is a replacement seal designed to join the valve cover to the cylinder head on Caterpillar engine platforms, enabling a tight, leak-resistant interface that maintains oil containment under the stresses of starting, running, and thermal cycling. It is specified to fit Caterpillar 3114, 3116, and 3126 engines, aligning precisely with the valve cover mounting surfaces so technicians can restore an original, factory-intended seal after gasket wear, valve cover service, or routine maintenance. This gasket works as part of the upper end seal to contain engine oil in the valve cover region and protect the valve train from contaminants, helping maintain proper lubrication and the integrity of the valve cover joint. Use the 119-2940 valve cover gasket with the corresponding valve cover on the indicated engine models to complete maintenance tasks and return the engine to its intended performance and reliability across service intervals, ensuring long-term sealing performance.
