PAI Valley Pan Gasket

The PAI Valley Pan Gasket helps service shops refresh International and Navistar 6.9, 7.3, and 444 series engines where top-end sealing is critical after cylinder head or intake work. It sits in the lifter valley area, forming a barrier that separates engine oil from coolant passages while the engine runs in heavy-use commercial duty. The gasket profile works with factory-style hardware, helping keep alignment steady as components are torqued back into place. Mechanics working on older fleets appreciate a valley pan gasket that fits specific engine families without guesswork or improvisation. The PAI 431377 gives rebuilders a sealing choice tailored to these well-known medium-duty diesel platforms.
