Problems with the Oil Bath Timing Belt of the Puretech 1.2 Engine

Model: (Various brands) Various
Part: Timing belt

Video tutorial

In this video, you will see the issue with vehicles equipped with the Puretech 1.2 engine, which has an oil bath timing belt. In fact, many manufacturers work with this system, believing that the oil bath timing belt can provide smoother engine operation, extending the belt's lifespan, but we can see that in many cases, this is not true.

We perform a test with a special gauge to measure the width of the belt, and we see that the damaged belt has widened and has also torn. If you want to do a proper job during replacement, you must also change the water pump, the tensioner, all gaskets, and of course, the engine oil and filter; indeed, it is very likely that parts of the belt remain trapped in the oil filter mesh, as we can see from the footage, which shows the filter completely clogged with debris that has detached from the belt.

It will also be necessary to change the oil pump, which may have "digested" these residues; the vacuum pump should also be checked and replaced.
