Is the 1.5 VTi-TECH / T-GDI reliable?

MG/SAIC's "1.5" covers two different engines: the naturally aspirated VTi-TECH (106 hp), the entry-level engine in the MG ZS, and the turbocharged T-GDI (162-170 hp), found only in the MG HS and as the petrol engine in its plug-in hybrids. Neither has well-documented engine faults in independent sources yet: the complaints published concern electronics, the automatic gearbox and finish, not the engine block.[1][2][3][4][5][6]

Is the 1.6 and 2.0 8v EA827 reliable?

Simple, naturally aspirated petrol engines that, according to the sources, last a long time with regular maintenance. Gebrauchtwagenberater describes the 8-valve 1.6 as old-fashioned but reliable, and the 102 hp 1.6 MPI as even more reliable than the 1.4 16v. Watch the timing belt with the water pump, coolant leaks, oil consumption (especially on the 2.0) and idle and sensor faults.[7][8][9][10]
