Mercedes Benz М104 is a 6-cylinder in-line engine with a cast iron block with a volume (respectively) of 3.0 l and 3.2 l with variable valve timing. Replaced a motor marked M103. On engines without an ignition distributor, the intake camshaft was equipped with an electro-hydraulic clutch to change the valve timing. The phase change took place without smooth adjustment – only two extreme positions (“earlier” – “later”).
