🔌 Function

Seals combustion pressure, coolant and lubricating-oil passages between the cylinder head and crankcase.

⚠️ Common Signs of Failure

• White steam from the exhaust and coolant loss with no external leak
• Bubbles or pressure in the expansion tank and a rising coolant temperature
• Mayonnaise-like emulsion under the oil filler cap, or oil found in the coolant
• Combustion knock, hard starting and low compression on one cylinder
• Gasket found burnt through between cylinders or eroded at a coolant hole

🛠️ Service Notes

• Remove all old sealing material without damaging the mating faces and confirm the correct seal grade or thickness.
• Lubricate only where specified, install without twisting, and pressure-check the system after assembly.
• The D7E pair is 20833938 at 1.15mm (one dot) and 20833939 at 1.25mm (two dots) - select from measured piston protrusion, not from the marking on the gasket removed.
