( Manufacturer Part Number: 901-760-16-61 ), ( Genuine Oem: Yes ), ( Manufacturer Warranty: 1 Year ), ( Fitment Type: Direct Replacement )
The **Mercedes-Benz 901-760-16-61** is a specialized internal component, specifically a **cylinder head gasket set** designed for the iconic **M117 V8 engine** found in select Mercedes-Benz models, including certain iterations of the **W116 (S-Class), W108 (280SE/280S), and W111 (300SE)** from the late 1960s to the early 1970s. This gasket set plays a critical role in maintaining the engine s structural integrity and sealing efficiency, ensuring optimal compression, combustion, and lubrication within the cylinder head assembly. Crafted from high-grade **composite materials**, including reinforced silicone, fiberglass, and copper-based alloys, the gasket set is engineered to withstand the extreme thermal and mechanical stresses inherent in high-performance V8 engines, which operate at pressures exceeding **150 psi (10.3 bar)** per cylinder during peak combustion cycles. The **901-760-16-61** designation itself encodes vital technical details: the **901** refers to the original Mercedes-Benz part numbering system for the M117 engine family, while **760** indicates the specific gasket configuration for the **16-valve overhead camshaft (OHC) design** a hallmark of the era s advanced valve train systems. The **16** denotes the number of individual gaskets included in the set, covering the **intake manifold, exhaust manifold, oil control, and combustion chamber seals**, each meticulously machined to precise tolerances (typically ** 0.05 mm**) to prevent leaks or warping under high-temperature conditions. Internally, the gasket set features **multi-layered construction**, with the **outermost layers** providing structural rigidity to resist deformation from cylinder head clamping forces (often **100 120 Nm** per bolt), while the **inner layers** incorporate **metallic reinforcement rings** at critical sealing interfaces such as the **spark plug bores and valve guide passages** to prevent blow-by and ensure long-term durability. The design also incorporates **asymmetrical sealing lips** tailored to the engine s **cast-iron cylinder head**, which features **drilled coolant passages** and **integrated rocker cover mounts**, necessitating a gasket with precise alignment features to avoid misalignment-induced stress. When installed, the gasket set interfaces directly with the **camshaft cover, oil filter housing, and intake/exhaust manifolds**, forming a hermetic seal that prevents **coolant, oil, and combustion gases** from escaping into the engine bay or mixing with unintended fluids. Proper installation requires **torque sequencing** (typically **10 Nm 20 Nm 30 Nm 40 Nm** in a star pattern) to gradually compress the gasket material evenly, avoiding localized stress points that could lead to premature failure. Over time, exposure to **high-temperature combustion gases (up to 2,500 C in the combustion chamber)** and **vibration from the engine s 90-degree V8 layout** can cause the gasket to degrade, leading to **coolant leaks, oil dilution in the combustion chamber, or catastrophic head gasket failure** a condition historically known as the **"Mercedes head gasket curse"** among classic car enthusiasts. Replacement of the **901-760-16-61** set is often recommended during **major overhauls** or when symptoms such as **white smoke from the exhaust, overheating, or a sweet coolant smell** indicate compromised sealing. While modern aftermarket alternatives exist, the original **Mercedes-Benz OEM gasket set** remains the preferred choice for purists and restorers seeking to preserve the engine s original performance and reliability, as it is specifically calibrated to the **M117 s unique cylinder head geometry** and **valve train dynamics**. Whether used in a **restored show car** or a **high-mileage daily driver**, the **901-760-16-61** gasket set exemplifies Mercedes-Benz s engineering precision of the 1970s, balancing durability with the need for precise sealing in one of the most iconic V8 engines of its time.
