Mercedes Benz — M272 Engine Parts Diagram

The two-piece reservoir that seals the bottom of the engine and houses the oil pick-up tube. 2. Cylinder Head & Valvetrain (Top End)

Includes the updated shaft, chain, guides, and gaskets.

The camshaft adjusters are often shown as circular units with oil passages. On the M272, both intake and exhaust camshafts have variable adjustment (on most versions), making the diagram quite busy at the front of the engine.

: The system switches between long runners (for torque below 3900 RPM) and short runners (for power at high RPM). 3. Timing and Valvetrain Components

Secures the crankshaft tightly to the engine block.

The M272 features a complex Double Overhead Cam (DOHC) system with continuous Variable Valve Timing (VVT) for both intake and exhaust. The two-piece reservoir that seals the bottom of

An electronically controlled butterfly valve regulating overall air entry.

The foundation of the M272 is a lightweight, cast-aluminum silicon (Alusil) engine block. Because of this specialized cylinder wall material, standard cast-iron piston rings can run directly against the bores without heavy steel sleeves. The camshaft adjusters are often shown as circular

The chain has four colored (orange/dark) links that must align with the crank gear, balancer shaft, and cam adjuster marks. Conclusion

The M272 is a masterpiece of early 2000s engineering that delivered impressive power—up to 268 hp in its 3.5L variant—but its complexity necessitates a proactive approach to maintenance. For anyone performing repairs, technical manuals like the Mercedes Engine M272 Manual Model 212 Engine Guides

Plastic rails that direct the chain path and prevent whipping inside the timing cover.

The Mercedes-Benz M272 engine is a 90-degree V6 family known for introducing continuous variable valve timing (VVT) on both intake and exhaust camshafts. This engine architecture features an aluminum block, magnesium intake manifold, and a counter-rotating balance shaft to eliminate vibrations inherent in its 90-degree design.
