Citroën C4 came in with engine trouble. We discovered the wet belt was breaking apart and blocking oil galleries. Risk of major damage if left unchecked.
This Citroën C4 was brought into 1Stop Motor Shop in Newtownabbey with reported engine trouble. After running full diagnostics, we uncovered a serious issue: the wet timing belt was breaking apart, with fragments blocking vital oil galleries inside the engine.
A wet belt (or oil-immersed timing belt) runs inside the engine, lubricated by oil. While quieter and more efficient than traditional belts, they degrade over time—especially with:
Missed oil changes
Low-quality engine oil
Poor maintenance history
As the belt breaks up, it releases particles that clog oil galleries, cutting off lubrication to essential components. This can lead to:
Low oil pressure
Camshaft and crankshaft damage
Full engine failure if not caught early
This C4 showed typical signs:
Rough idle
Warning lights (EML)
Strange noises from the engine bay
Reduced engine performance
