Description of the motor device OM 616 2.4 diesel
The ancestor of the 4-cylinder diesel series, the 1.9-liter OM621 engine, appeared in 1958. In 1968, it was replaced by a newer power unit of the OM 615 series with a volume of 2.0 and 2.2 liters. Finally, in 1973, the 2.4-liter OM 616 engine we are describing debuted. The design of this atmospheric swirl-chamber diesel engine was classic for that time: a cast-iron cylinder block with liners, a cast-iron 8-valve head without hydraulic lifters and a two-row timing chain that rotates a single camshaft, and another in-line injection pump Bosch M.
Engine number OM616 is located at the junction of the block with the head
In 1974, on the basis of this power unit, a 5-cylinder engine of the OM617 series was created.

Disadvantages, breakdowns and problems of the OM 616 engine
This is a very reliable and hardy diesel engine with just a huge resource and the most famous weak point is the rear crankshaft seal in the form of packing, which often leaks, which can lead to oil starvation and expensive repairs.
At Bosch M injection pumps with vacuum control, the rack drive membrane often breaks, but the pumps of the updated units of the MW and M / RSF series no longer have this problem. Also, due to the wear of the seals, the booster pump may unexpectedly fail.
Despite the fact that the motor is equipped with a double-row timing chain, it does not last very long. They change it about once every 200 - 250 thousand km, often together with dampers and stars.
The manufacturer claims the resource of the OM 616 engine is 240 km, but it runs up to 000 km.
