We disassembled the legendary EP6 engine, created by the efforts of PSA and BMW. This 1.6-litre engine was installed on Peugeot, Citroёn, Mini, and then on the BMW 1- and 3-series. Legends about this engine are associated with its insecurity and blunders in its design. However, thousands of such engines have failed due to excessively long oil change intervals. In general, we got the longest disassembly.
