Is the BMW N13 reliable?

The BMW N13 (2011-2016), BMW's first turbocharged four-cylinder in three decades, powered the 114i, 116i, 118i and 120i (F20/F21) and the 316i (F30). It derives from the Prince engine developed with PSA, the same origin as the 1.6 THP. In 2013 BMW issued a technical service bulletin over timing chain and tensioner wear; oil consumption and carbon build-up on the injectors are other weak points shared with that family.[1][2][3]

Is the Rover K-Series reliable?

The Rover K-Series has one very well-known fault: the head gasket, which according to Diariomotor can fail at under 100,000 km and which technical sources link to a small cooling circuit and a badly placed thermostat. The usual repair uses the multi-layer (MLS) gasket developed for the Freelander; the other two documented faults (sunken liners and coolant leaks) are related to that same circuit.[4][5][6][7]
