Honda Civic D-series Head Gasket – Elring 920.306 (graphite)

The Elring 920.306 head gasket is a classic graphite composite gasket designed for older Honda D-series engines used in Civic models from 1988–1995. The graphite layer on a steel core adapts well to slightly aged block and head surfaces, ensuring reliable sealing of the combustion chambers as well as oil and coolant passages.

It is an excellent OE-style choice for a standard engine rebuild or head-gasket replacement on a mostly stock engine. If you are planning high power, forced induction or very hard use, it is worth considering a modern MLS steel head gasket, which offers higher durability under extreme conditions.

Why choose the Elring 920.306 head gasket?

• Graphite composite design – very forgiving on older engines with minor surface imperfections.
• Exact fit – made specifically for listed Honda D-series engines, no modifications required.
• Quality brand – Elring supplies many gaskets to OEM and OE-equivalent markets.
• Great for stock rebuilds – ideal as a service replacement on daily-driven classic Civics.

When should the head gasket be replaced?

• Oil in coolant or “mayonnaise” under the oil cap,
• Coolant loss with no visible external leaks,
• Combustion gases in the cooling system (hard hoses, bubbling in the expansion tank),
• Uneven running or low compression on one or more cylinders.

When replacing the head gasket, it is strongly recommended to check head flatness (and resurface if needed), use new head bolts and make sure the cooling system is in good condition to avoid overheating after the rebuild.
