Product Details

The Cometic C5866-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Oldsmobile LD9 Quad 4 engines. This precision gasket features a .040" (1.0mm) compressed thickness and a 3.595" bore diameter to provide an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .040" compressed thickness provides excellent torque retention and combustion sealing
  • 3.595" bore diameter designed for LD9 Quad 4 specifications
  • Non-EGR design for engines without exhaust gas recirculation systems
  • Embossed stainless steel layers with advanced coating technology resist corrosion and blow-out
  • Conforms to irregular sealing surfaces while maintaining consistent clamping pressure

Cometic MLS gaskets are the preferred choice for performance builds, offering exceptional reliability under high compression and boost applications. The multi-layer design allows for controlled expansion and contraction during heat cycles, ensuring a reliable seal throughout the engine's operating range.
