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 2.0 16v F4R and F4RT reliable?

In the sources we consulted, the 2.0-litre F4R and F4RT show no engine-destroying design faults, but the timing belt must be changed on time, and the coils (RS) and the variable valve timing pulley appear as weak points. We have found no reliable sources on oil consumption or big-end bearings.^{[7][8][9][10]}
