Engine Mercedes M112 E37

In 2002, another version of the M112 engine appeared – the E37 with a volume of 3.7 liters. This option is recognized as the largest in the series. To increase the volume, the BC was changed for a piston with a large diameter. The cylinder head does not differ from the base M112: it has one camshaft and 3 valves per cylinder. The head uses the IFGR system, hydraulic lifters and an intake manifold with an adjustable length. The average resource of the timing chain drive reaches 200,000 km, which is an undoubted plus. The disadvantages include excessive oil consumption, oil leaks, delamination of the crankshaft pulley damper. As with all engines, high-quality consumables and gentle driving style are relevant for the M112 E37.
