- Oil Leakage: A common issue in Song PLUS DM - i, the valve oil seal OE 1049926100 may not seal properly, leading to oil seeping into the combustion chamber.
- Valve Stem Wear: In DENZA D9 series including DM - i, PHEV and Hybrid models, the valve oil seal can cause accelerated valve stem wear over time.
- Poor Sealing Performance: The valve oil seal OE 1049926100 might lose its elasticity, resulting in poor sealing in these vehicles.
Maintenance Tips of BYD 1049926100 Valve oil seal for Song PLUS DM-i/DENZA D9 DM-i/DENZA D9 PHEV/DENZA D9 Hybrid
- First, before installing the BYD valve oil seal (OE# 1049926100), make sure the valve stem is clean and free of debris. This helps prevent premature wear of the seal.
- When replacing the valve oil seal on Song PLUS DM-i, DENZA D9 DM-i, DENZA D9 PHEV, or DENZA D9 Hybrid, use a proper seal installation tool to avoid damaging the seal.
- Check the valve guide for wear. A worn guide can cause the valve oil seal to fail quickly. Replace the guide if necessary.
- Apply a thin layer of engine oil to the valve oil seal before installation. This reduces friction and makes the installation smoother.
- Ensure the valve oil seal is correctly seated. An improperly seated seal can lead to oil leakage and poor engine performance.
Warning: Do not over-tighten the valve oil seal during installation. Over-tightening can cause deformation and lead to seal failure.
