Engine Peugeot EP6C

The 1.6-liter Peugeot EP6C or 5FS engine was assembled at the company’s plant from 2009 to 2018 and installed on many popular concern models, such as 208, 308, 408, as well as 3008 and 5008. There was a reduced power version of this unit under its own index EP6CB.

At the beginning of 2009, an updated modification of the EP6 gasoline engine was introduced, created in collaboration with BMW. On Mini vehicles, this unit is known as N16B16A. The basis of the design has not changed: there is an aluminum cylinder block with cast-iron liners, a 16-valve cylinder head with hydraulic compensators, distributed fuel injection, a timing chain, Vanos-type phase regulators on two shafts, and a Valvetronic throttleless control system.

The main differences were a new oil pump with both pressure and flow control, a new vacuum pump, and an even more modern water pump with an electromagnetic clutch. The motor received an advanced catalyst, which allowed it to fit into the strict Euro 5 environmental standards, special grooves were applied to the crankshaft liners to reduce friction and increase the resource, and the lubricant pressure sensor finally moved from the block head to the oil filter bracket.

Naturally aspirated Prince family: EP3, EP3C, EP6, EP6C, EP6CB.

Disadvantages of the Peugeot EP6C engine

• In the updated units, the timing chain has been revised and its resource has increased significantly, but still requires replacement at low mileage: it was 50,000 km, it has become 100-150 thousand km. The upside is that there are plenty of cheap substitutes on the market.
• The new oil pump with the ability to adjust the pressure and lubricant flow often wedges and the danger is that this can happen in the minimum performance mode. Then the liners will very quickly pull up in the motor, and maybe the camshaft as well.
• A lot of complaints on specialized forums are related to malfunctions in the Valvetronic system. With the update, the Vanos phase regulator valves received a filter, but their resource did not increase.
• Still often in these motors there is an oil burner due to the occurrence of piston rings or wear of valve stem seals, leaks of lubricant or antifreeze constantly occur, cases of falling valve seats are recorded and the pump and thermostat serve very little.
