Detailed Description

This Elring cylinder head gasket is engineered for engines that require accurate head-to-block sealing under heat, pressure, and repeated thermal cycling. The MLS design uses layered steel construction to help maintain sealing integrity across the combustion chamber, coolant passages, and oil galleries. For BMW M240i, M340i xDrive, X3, X5, X6, Z4, 540i, 740i, 840i, X7, and related Toyota GR Supra and Supra applications, the gasket supports the factory-style sealing profile specified by the engine platform. Elring 793.491 is a direct-fit sealing component for service work where head gasket replacement is required.

What It Helps Address

• Combustion gas leakage at the cylinder head interface
• Coolant seepage between the head and engine block
• Engine oil leakage from a compromised head gasket seal
• Compression loss that can affect idle quality and power delivery
• Sealing issues after cylinder head service or engine teardown

Installation Notes and Tips

Inspect the cylinder head and engine block mating surfaces before installation. Verify surface flatness, clean all sealing faces thoroughly, and follow the manufacturer’s torque sequence and angle specifications during assembly. Confirm the correct gasket thickness and diameter for the engine code before installation. For BMW M240i, M340i xDrive, X3, X5, and Toyota GR Supra service, match the gasket to the exact engine variant and reuse only approved fasteners and procedures specified by the vehicle manufacturer.
