Which engines use an oil bath belt?

Model: (Various brands) Various
Part: Timing belt

Video tutorial

In this video, we talk about the now infamous oil bath timing belts: this type of belt was designed to last longer, but in reality it deteriorates inside the oil, losing fragments and clogging the filters and the oil pan, damaging the entire lubrication system of the car. But which engines use these oil bath timing belts? The Puretech engines of the PSA group (Peugeot and Citroen) until 2018; the 1.0 Ecoboost engines of Ford, but not all of them.

It is used in the SFJE with 101 hp; the M1JL with 125 hp and YYIE with 140 hp; while the B7JA with 125 hp uses a chain, like the M0JB. On the Opel Corsa, the 1.0 3 Cylinder engine uses the oil bath timing belt, as well as the Astra and Mokka which use the Puretech engine.

Even the Jeep Avenger with the 1.2 Puretech engine has this problem. The youtuber also talks about Volkswagen, but the case of Volkswagen (and the group) is different: especially those with common rail engines use an oil bath timing belt, but to operate the oil pump, not for engine timing.
