If liner protrusion is insufficient, which condition is most likely to occur?

• A. Insufficient sealing
• B. Liner flange damage
• C. Over cooling of the cylinder head
• D. The engine would over heat

Answer: (A)

Insufficient liner protrusion means the cylinder liner sits too far back from the engine block surface, reducing the squeeze against the head gasket and cylinder head. That weakened contact prevents a proper seal, so compression can escape and cooling/oil leaks can occur. So the most likely condition is insufficient sealing. Liner flange damage is more tied to excessive protrusion or misalignment, and over cooling or overheating relate to cooling system issues rather than the seal formed by liner position.
