MD349347 Mitsubishi GASKET,CYLINDER HEAD, Price: 73.36$, Weight: 0.33kg

OEM‑grade cylinder head sealing gasket for Mitsubishi engines

Why this part is needed

This thin but tough seal sits between the engine block and the cylinder head. It locks in combustion pressure, keeps coolant and oil in their own passages, and stops outside leaks. A healthy head gasket protects power, fuel economy, and emissions, while preventing overheating and cross‑contamination. It is essential every time the head is removed or when old sealing surfaces can no longer hold pressure.

How it works

Made from multi‑layer steel with elastomer coatings, it uses reinforced fire rings around each cylinder to contain extreme pressure and heat. Micro sealing beads surround oil and coolant ports to block fluids. When head bolts are tightened in sequence, clamping force makes the layers conform to tiny surface irregularities. The design tolerates heat cycles and vibration, maintaining a precise, durable combustion seal .

What happens if it breaks

Typical signs include white exhaust smoke , sweet coolant smell, bubbling in the reservoir, misfires, overheating, low compression, and milky oil. Keep driving and you risk warped head, eroded block, catalyst and O2 sensor damage, bearing washout, or even hydrolock. Power drops, fuel use rises, and repair costs climb fast ⚠️.

Install and service tips

• Check head/block flatness; resurface if out of spec.
• Clean decks carefully; no gouges. Align dowels.
• Use new head bolts if torque‑to‑yield; follow torque/angle sequence.
• No extra sealant unless the service manual specifies.
• Flush coolant, change oil and filter after repair .
• Bleed air, verify fan operation, and recheck levels after first heat cycle.

Choose this premium head gasket for reliable sealing, stable temperature control, and restored compression on compatible Mitsubishi engines.
