11044AA642 Subaru GSKT-CYL HEAD, Price: 31.66$, Weight: 0.13kg

Subaru Cylinder Head Gasket – OEM‑grade Seal

This precision gasket seals the joint between the aluminum cylinder head and engine block on Subaru boxer engines. It locks in combustion pressure while keeping coolant and oil in their own passages. Ideal for overhaul or head service, it restores factory compression, clean emissions, and smooth idle.

Why you need it

It prevents power loss, overheating, and fluid mixing. After overheating, warping, or head machining, a new seal is mandatory to protect the engine and keep efficiency high.

How it works ⚙️

Multi‑layer steel (MLS) with reinforced fire rings compresses under head bolts. Heat‑resistant coatings fill micro‑imperfections, resisting detonation, thermal cycling, and ensuring correct quench and gasket crush.

If it fails

Symptoms include white exhaust smoke, sweet smell, coolant loss, milky oil, bubbling in the tank, misfires, poor heat, and overheating. Continued driving can score cylinders, warp heads, and ruin bearings.

Tech notes

Check head/block flatness, clean threads, follow torque‑angle sequence, renew bolts if stretch‑type, and bleed the cooling system carefully.
