Valve seals Yanmar 3TNV88 – 3TNE88 | 4TNV88 | 3TNV84 | YM series

Description

New valve stem seal (also known as valve seal or valve stem rubber) suitable for the Yanmar 3TNV88 three-cylinder diesel engine and the complete TNE/TNV engine series. The seal closes the gap between the valve stem and the valve guide, preventing engine oil from leaking into the combustion chamber.

✔️ Prevents oil leakage along the valve stem — less blue smoke and lower oil consumption
✔️ Exact OEM fit — 1-to-1 replacement of the original
✔️ Fits the complete Yanmar 3TNE / 3TNV / 4TNE / 4TNV engine series and the Komatsu 3D88E
