The M271 E18 cylinder block served as the foundation for the development of the Mercedes M271 E16 engine, which was manufactured between 2008 and 2011 and had a corresponding short-stroke crankshaft installed (the stroke was reduced to 75.6 mm). A 1597cc inline 4-cylinder gasoline engine powers the M271 E16.
M102, M111, M166, M254, M260, M264, M266, M270, M271 E16, M271 E18, M274, and M282 are R4 Mercedes engines.
Cast-iron sleeves are poured into an aluminum cylinder block that has been cast. A Lanchester balancing mechanism with two balancing shafts and an integrated oil pump is located at the bottom of the block.

Disadvantages of the M271 E16 engine
The most well-known engine issue is soot-related stuck exhaust valves.
The erratic timing chain, which can extend up to 100,000 kilometers, comes in second.
Frequent lubricant leaks from the heat exchanger or oil filter housing come next.
The tubes burst due to the rapid deterioration of the crankcase ventilation system.
Fuel seeping into the oil is a proprietary EVO series engine malfunction.
