Is the M60 and M62 reliable?

BMW's M60 and M62 V8s have a reputation for durability if the cooling system is looked after, but the M62 carries two well-documented weak points: the plastic chain guides of the timing chain and, from 1998, the VANOS seals. The M60 suffered cylinder wear from Nikasil with sulphur-contaminated petrol.[1][2][3][4]

Is the 1.2 8v reliable?

The 1.2 8v (D7F) is a simple naturally aspirated engine of 54 to 60 hp, with a timing belt, which Renault fitted from 1996 to the Twingo, Clio II and Kangoo. No catastrophic failures are documented; what owner reviews mention most often are the sensors, the cylinder head gasket, the coil packs and the occasional oil drip.[5][6][7]
