The Ford 1.0 EcoBoost, Ford Transit 2.0 EcoBlue and Peugeot, Citroën & Vauxhall 1.2 PureTech engines use a timing belt that runs inside the engine oil. When that belt starts to break down, it can block the oil pickup and destroy the engine. We replace wet belts properly — correct parts, correct procedure, straight advice.
The basics
On most engines the timing belt runs dry, outside the engine, behind a plastic cover. On a "belt-in-oil" engine the belt sits inside and spins through the hot engine oil. It was done to cut friction, noise and emissions — but rubber and hot oil are not natural companions.
Over time the belt material degrades and sheds tiny rubber particles into the oil. Those particles are carried round the lubrication system until they reach the fine mesh oil pickup strainer in the sump. As it clogs, oil pressure falls, the turbo and valve gear are starved, and the weakened belt can jump teeth or snap — and on these engines, a snapped belt usually writes the engine off. Short journeys and town driving make it worse, because the oil rarely gets fully hot.
The belt runs through the engine oil rather than in a dry housing.
Degrading belt material collects in the sump and blocks the oil pickup.
Replaced in time, it's a planned repair — left too late, it's a new engine.

Not sure which engine you have? Send us your registration or call 01787 743055 — we'll confirm whether your car or van has a wet belt, a chain, or something else entirely, before you commit to anything.
Don't ignore these
As the belt sheds rubber, the particles clog the oil pickup strainer in the sump. Oil flow drops and the pressure warning appears — often at idle first.
A rattle or whine from the front of the engine during the first few seconds after a cold start is one of the earliest audible signs of a worn belt.
Black rubber particles or a thick, gritty film in the oil mean the belt is already breaking down into the sump.
A stretched or worn belt can slip a tooth, throwing the timing out. Rough idle, misfire codes or a sudden loss of power need checking straight away.
Seeing any of these? Stop driving and call us on 01787 743055. A wet belt inspection costs far less than the engine it protects.
The work
We confirm the exact engine code and build date, and check whether your car has a belt or a chain before quoting.
Oil condition, dipstick and sump debris are checked so you know exactly how far any degradation has gone.
Belt, tensioner and oil pickup screen are renewed with OE-quality parts, and the engine is refilled with the correct specification oil.
Oil pressure is verified, the car is road-tested, and the work is stamped into your service history.
If the engine has already been damaged, we can help there too — our workshop carries out in-house engine rebuilds, reconditioning and engine supply and fitting.
