Over time the cylinder‐base gasket can degrade due to thermal cycling, vibration and age, leading to oil seepage, reduction in compression sealing or potential engine case contamination. Replacing it with a high-quality replacement gasket ensures the joint is properly sealed, avoids loss of performance and prevents possible engine damage.

Replace when:
• You are performing an engine rebuild or cylinder removal.
• You detect oil seepage or visible signs of leakage from the cylinder base area.
• You observe compression loss, or gasket part numbers are referenced in service documentation for your engine variant.
