SEAL - VALVE STEM (Mitsubishi MB32A0402801)

A worn valve stem seal can allow oil to enter the combustion chamber, causing blue exhaust smoke and increased oil consumption. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB32A0402801. The seal controls lubrication to the valve stem while preventing excess oil from passing into the cylinder. Over time, heat and pressure degrade the seal material, leading to reduced sealing performance. A failed seal may also contribute to carbon buildup on valves and spark plugs. The item ships at approximately 0.012 POUNDS. Verify the serial number or application, then call (562) 693-7748.
