Wet Belts and Why Do They Matter?
Wet belts (also known as belt-in-oil timing belts) are increasingly common in modern petrol and diesel engines. Designed to run inside the engine in oil for reduced noise and wear, they require careful maintenance and timely replacement. If left unchecked, a degraded wet belt can cause severe internal engine damage, MOT failure, or complete breakdown.

Without Timely Wet Belt Replacement
Wet belts—also known as belt-in-oil timing systems—are a known weak point in many modern engines, particularly if they aren't serviced
at the correct intervals. In this gallery, we share real-life examples of the kind of damage we regularly see in our workshop when wet belts begin to fail.
From missing belt teeth and degraded rubber debris contaminating the oil system, to blocked oil pickups and severe top-end engine damage from oil
starvation—these images show just how critical it is to inspect and replace wet belts before failure occurs.
If you suspect a wet belt issue, don't delay. Early diagnosis and intervention can prevent catastrophic engine failure and save you thousands in repair costs.
