It contains all necessary gaskets, seals, and o-rings for the oil pan, front and rear crankshafts, timing cover, oil cooler, and other lower engine components. Replacing these seals during a rebuild or repair prevents oil and coolant leaks and helps maintain proper lubrication. The set is typically used together with an upper head gasket set for a complete engine overhaul.
