  What Is This Part?

A cylinder head gasket forms the sealing interface beneath the cylinder head. When the head is secured, the gasket is compressed between the mating surfaces to seal the combustion chambers and the fluid passages crossing that joint. This version is identified for cylinders 1–3, so the cylinder-bank application matters when selecting it for a repair. Effective sealing also depends on the condition of the head and block surfaces and the correct installation procedure. 

What Does This Part Do?

• Seals combustion pressure: Closes the head-to-block joint around the combustion chambers.
• Seals coolant passages: Helps contain coolant where it passes between the block and cylinder head.
• Seals oil passages: Helps contain the lubricating oil passing through the joint.
• Separates engine circuits: Maintains sealing boundaries between combustion gases, coolant and oil. 
  
  Why Replace This Part?

Replacement may be needed when inspection confirms leakage or damage at the cylinder head joint. Overheating, distorted mating surfaces, incorrect positioning or inadequate clamping can compromise the seal. The underlying cause should be investigated rather than assuming that a new gasket alone will resolve the problem. 

During cylinder head repairs, check surface condition, locating sleeves and fastening requirements before reassembly. Follow the engine-specific preparation and tightening instructions; a gasket cannot compensate for damaged or incorrectly prepared mating surfaces. 

When to Replace This Part?

• Confirmed joint leakage: Oil or coolant is traced to the head-to-block interface rather than a nearby seal or connection.
• Combustion leakage: Testing identifies combustion gases escaping through the cylinder head joint.
• Overheating damage: Inspection reveals gasket damage or distortion of the adjoining surfaces.
• Visible gasket damage: Dismantling reveals burnt sealing areas, damaged openings or evidence of incorrect seating. 
  
  Where Is This Part Fitted?

Location: Between the engine block and the cylinder head serving cylinders 1–3, within the cylinder head assembly.

  FAQs

• Does low compression automatically mean this gasket has failed?
  No. Compression and leak-down testing can help establish the source of a sealing problem before dismantling or selecting replacement parts.
• Should the cylinder head be checked during replacement?
  Yes. Check the mating surfaces for damage and flatness, particularly after overheating, and follow the engine-specific repair instructions.
