Video tutorial

In this video we can see that there are also efficient oil bath belts, such as those of the VAG group: in fact, these belts do not move the distribution, but only the oil pump, which is a less critical task compared to synchronizing the entire engine; it is then designed with specific materials, to withstand continuous immersion in engine oil, and also possible contamination with diesel.

Furthermore, it works continuously immersed, so this environment does not degrade it, but preserves it by lubricating and keeping it flexible; it is also oversized for its task.

The youtuber in the video explains the difference with the disaster of the PSA, where the problems were caused by gasoline vapors and oil degrading the rubber; furthermore, the belt moved the distribution, which was a huge effort. The manufacturer indicates an expiration date, but the youtuber confirms having seen belts with 400,000 km still in good condition, so he considers it a component capable of lasting as long as the car itself.
