Presentation of the PureTech engines:

The Peugeot EB2 PureTech engine is a compact and light 3-cylinder engine that was launched by December 2011 as a new generation efficient ICE.
Depending on the vehicle or application, this engine exists in a naturally aspirated version with indirect injection or a turbocharged version with direct injection, and different sub-versions which adapt its flexibility or maximum power to the weight or type of vehicle.
The below tutorials do show how to maintain or rebuild the atmospheric version with indirect injection (2012 Peugeot 208 1.2VTi) and a variable valve timing on both intake and exhaust camshafts, developing a power of 60KW / 82HP and a torque of 116 N.m at 2750 rpm.

Reliability of the Puretech engines:

Having driven, maintained and rebuilt the EB2F version over 154,000 km, our opinion remains very favorable regarding the efficiency of this engine, its viability, its reliability (not once broken down) and its ease of maintenance.
It has however two problems of premature wear:
  1. Overconsumption of oil resulting from an early wear of the piston rings, which can occur from km 70,000 onwards, and from which results the rest of the problems, if left untreated. To note that our vehicle was often driven uphills, at high rpms, and in a country with low octane gasoline, generating knocking all the time.
  2. Similarly, its "submerged" timing belt must be replaced every 70,000 km instead of the 200,000 initially hoped for by Peugeot. Indeed, the contaminants in the engine oil quickly degrade it. 
While it is mandatory to replace the timing belt every 70,000Km, the first replacement of the piston rings can be logically performed around the 150,000 Km mileage. In the meantime, thicker oils should be used to reduce the oil consumption as much as possible, see further below for details.

Peugeot EB2 engine identification plates

The identification plates of the EB2 engine can be found as follows:
Two of them are constructor's plates that are directly molded in the engine block in between the alternator and the catalytic converter
Another one consists of engraved text in the engine block itself and can be found to the right side of the engine (left side of the vehicle) just under the cylinder head gasket (picture to the right).
A quick identification of the engine name and version is embossed on the cylinder head too and precisely on the exhaust manifold as shown here below:
