Multi-Layer Steel (MLS) Cylinder Head Gasket 0.75 mm Thickness for Toyota 1KZ-TE 3.0L Diesel Engine

The cylinder head gasket carrying Toyota OEM number 11115-67040 seals the critical interface between the cylinder head and engine block on Toyota's legendary 1KZ, 1KZ-T, and 1KZ-TE 3.0L turbo-diesel engine family. This factory-spec sealing component is designed for one of Toyota's most celebrated diesel power plants, used extensively across global markets from 1993 through 2009.

The 1KZ family is a 2,982 cc inline-4 DOHC 16-valve direct injection turbo-diesel engine with a bore of 96 mm and stroke of 103 mm, a compression ratio of 21.2:1, and power outputs ranging from 130 PS to 170 PS depending on the variant and market tuning.

This gasket is constructed from multi-layer steel (MLS) - multiple precision-stamped embossed layers of stainless steel with an elastomer coating on the outer surfaces. Key dimensions include:

• 97 mm diameter gasket bore
• 190 mm width and 465 mm length
• Compressed thickness: 0.75 mm (thinnest option in 1KZ family)
• Weight: Approximately 340 g

Toyota 1KZ-family diesel engines use five different head gasket thickness grades, identified by the number of notches or holes on the gasket's outer edge. The correct thickness is determined by piston protrusion measurements.

This Toyota cylinder head gasket 11115-67040 directly replaces the factory sealing component in the following configurations:

• Multi-Layer Steel (MLS) Construction: Withstands extreme cylinder pressures and resists corrosion from combustion by-products
• MARK 1 (1 Hole / 0.75 mm): Thinnest grade option for 1KZ-TE engines with lowest piston protrusion measurements
• Precision 97 mm Gasket Bore: Designed specifically for 96 mm pistons with proper sealing margin
• Elastomer Coating: Heat-activated coating seals microscopic imperfections without additional sealants
• Prevents Cross-Contamination: Maintains critical separation between cooling system and oil galleries
• Proven Reliability: MLS design maintains consistent clamping force through thousands of thermal cycles
• Global Coverage: Fits wide range of Toyota's most popular diesel vehicles across international markets

Recommended Replacement Indicators (1KZ-specific symptoms):
