Peugeot / Citroën 1.2 PureTech Timing Belt

Peugeot / Citroën 1.2 PureTech Timing Belt – Missing Teeth Explained

If you own or work on a Peugeot or Citroën fitted with the 1.2 PureTech engine, this is something you must be aware of.

In this video, I strip down a PureTech wet timing belt and show a common but dangerous failure – missing teeth on the belt. This issue often goes unnoticed until serious engine damage has already started.

(Video embedded above)

Why Missing Teeth on a PureTech Belt Is So Serious

Unlike a dry timing belt, the PureTech belt runs in engine oil. Over time, oil contamination causes the belt material to soften, swell, and break down.

When teeth start missing:

Valve timing becomes inaccurate
Camshaft timing can jump
Engine performance drops
Warning lights may appear
Catastrophic engine failure becomes a real risk

In many cases, engines with missing belt teeth are still running, which makes this problem especially dangerous.

Common Symptoms to Watch For

If you’re diagnosing a PureTech engine, these warning signs are critical:

Rattling or unusual engine noise
Engine management light
Poor starting or rough idle
Loss of power
Oil pickup strainer contamination

Ignoring these signs can lead to blocked oil ways, turbo failure, or complete engine damage.

Tools, Parts & Information Used

Final Thoughts

The PureTech missing teeth issue is not rare, and it’s not always obvious. This video shows exactly what to look for and why early inspection can save an engine.

If you’re working on one of these engines, don’t assume the belt is fine just because the engine runs.

👉 Watch the video, check the belt, and act early.

Cheap tools or expensive premium tools?

OK so I get the argument. I got the best tools, snap on, Mac tools etc with a lifetime guarantee! The other guy, your mate says “Look at these tools I just bought really cheap, why pay the price you paid when you can have them for a fraction of the price”. In my experience after 25 years in the motor trade I have come to a conclusion. But before I reveal, I have to say at the start of my time as a mechanic,I was snap on tools all the way. Unfortunately now after paying a stupid amount for tools it doesn’t matter. What good is a tool you Left on the bulkhead under the bonnet costing £60, or a tool that cost you £6. I know the answer. It’s no good. But the £6 one is easily replaceable. What’s more is that in my time in the trade I have found the quality to be almost as good as some premium tools. Not to say it’s the same. To conclude if you are totally obsessed with your tools and you put them away after every use definitely consider the premium tool. But if you’re the busy me...
