Is the 1.8 and 2.0 Zetec-E reliable?

The 1.8 and 2.0 litre Zetec-E engines in the Focus I are simple naturally aspirated petrol engines that, according to the sources, have no recurring serious fault. The most frequently mentioned issue is the plastic thermostat housing, which deforms and leaks coolant; in addition, Ford issued a recall in 2000 to replace the oil filler cap on 1.8 and 2.0 units built up to December 1999.^[1][2][3]

Is the 1.2 16v reliable?

The 1.2 16v (D4F) and its 8-valve predecessor, the D7F, are simple naturally aspirated engines, used for over two decades as the entry-level option in Renault and Dacia cars, with a reputation for reliability: the reliability pages consulted document no catastrophic failures and no oil consumption. The most-cited problems are ignition coils and sensors and, on higher-mileage cars, the head gasket.^[4][5][6][7]
