BlueTec Sprinter Valve Cover Gasket – 6540164400

SKU: 6540164400 - qty 1

Ensure a clean, leak‑free engine bay and proper valve‑train lubrication on your Sprinter with this OEM‑spec 6540164400 valve cover gasket — a critical seal that keeps engine oil where it belongs and protects internal components from contamination.

✅ What the Valve Cover Gasket Does & Why It Matters

• Seals the valve cover to the cylinder head: The valve cover (also called “rocker cover” or “cam cover” on many engines) encloses the top of the cylinder head and protects the valve train, rocker arms, camshafts, and related components. The gasket provides a seal between the cover and head — preventing oil from escaping and contaminants from entering. 

• Keeps oil inside the engine & protects lubrication system: Proper sealing ensures valve‑train components receive continuous oil supply. A failed gasket leads to oil leaks, reduced oil in critical areas, and can accelerate wear or damage to valves, camshafts, and lifters. 

• Prevents external leaks, smoke, and burning‑oil odor: Worn gaskets often allow oil to escape and drip onto hot engine parts (like exhaust manifolds), causing burning oil smells, possible smoke, and visible oil deposits. 

• Maintains engine cleanliness and avoids contamination: By sealing out dirt, dust, and moisture, the gasket helps preserve internal engine environment. Leaks can draw contaminants in, risking premature wear or damage to internal components. 

• Critical maintenance item — especially with age or after valve‑cover removal: Over time, rubber or composite gaskets degrade due to heat, vibration, oil exposure — becoming brittle or cracked. Replacing gaskets during maintenance avoids leaks and ensures long‑term sealing. 

🔧 Fitment & Replacement Notes

• This 6540164400 gasket fits defined engine/valve‑cover configurations for certain Sprinter diesel engines — confirm engine model and valve‑cover type before ordering.

• When installing: clean the mating surfaces (valve cover and head) thoroughly, remove old gasket/residue, then seat the new gasket properly. Avoid over‑tightening bolts — overtightening can deform the gasket, reducing sealing effectiveness. 

• If the cover has a built‑in breather/PCV system or detachable parts, ensure all sealing surfaces and bolts/clamps are correctly reinstalled.

• After installation: monitor engine for leaks, check around cover and spark‑plug wells (if applicable), and inspect oil level regularly to confirm proper sealing and oil containment.

🚐 Who This Is For / Use Cases

• Sprinter owners experiencing oil leaks, oil‑soaked valve cover, oil dripping onto exhaust/manifold, or burning oil smells — especially around the top of the engine.

• Vans undergoing valve‑train maintenance, valve‑cover removal, or regular engine service — replacing the gasket ensures proper resealing.

• High‑mileage or older Sprinter diesels where gasket material may have degraded from heat and age.

• Preventive maintenance for vans used often, under load, or in heavy‑duty applications — maintaining engine cleanliness, reliability, and longevity.
