Cylinder Heads

Sealing Combustion for Maximum Engine Power

Mechanics throughout the region know Raceway Nissan has the best selection and price for buying genuine OEM parts. Cylinder heads create the sealed top of your engine's combustion chambers. They house valves, camshafts, and passages that manage airflow, cooling, and lubrication. When cylinder heads fail, the damage can extend throughout the entire engine.

What Cylinder Heads Do in Your Engine

Cylinder heads bolt to the engine block and form chambers where fuel combustion occurs. They contain intake valves that allow air and fuel mixture to enter, plus exhaust valves that expel burned gases. Models like the Nissan Leaf and Nissan Titan use cylinder heads engineered for their specific power output and efficiency goals. Internal coolant passages circulate around hot zones to prevent warping from extreme temperatures. Oil channels provide continuous lubrication to valve train components during engine operation.

Why Cylinder Heads Crack and Warp

Overheating causes uneven metal expansion that warps the flat sealing surface with the engine block. This breaks the seal and allows coolant to contaminate engine oil. Valve seat erosion develops gradually from repeated combustion pressure and heat exposure. Corrosion forms inside coolant passages when maintenance schedules are neglected. Bolt threads strip when installation procedures don't follow proper torque specifications. Aftermarket cylinder heads frequently use inferior metal alloys that crack under thermal stress. We've replaced countless generic heads that failed while genuine parts would still be operating reliably.

When Cylinder Head Replacement Cannot Be Delayed

White exhaust smoke indicates coolant burning in combustion chambers from head or gasket damage. Milky, discolored oil on the dipstick means coolant is mixing with oil through head failure. Overheating that persists without visible coolant leaks suggests internal cracks in the cylinder head. Multiple cylinders showing low compression readings point to severe head damage requiring replacement. Genuine Nissan cylinder heads are machined to precise tolerances that ensure perfect sealing with your engine block. They integrate flawlessly with components like spark plugs to maintain proper ignition timing. Generic replacements might physically fit but rarely deliver the same precision or longevity.

From routine maintenance to major overhauls, Raceway Nissan has got you covered.
