Root Cause
The original hydraulic tensioner can gradually lose pressure under thermal cycling, allowing the timing chain to slacken, stretch, and eventually skip a tooth on the camshaft sprockets, risking catastrophic valve-to-piston contact.

Vehicle Value Check
Vehicle Value Check
A typical Hyundai i20 1.2-1.4 Petrol (2012-2014) currently holds a value of £1,500-£3,500 in the UK [THIRD-PARTY]. A £1,200-£2,200 rebuilt engine replacement represents a significant portion of the vehicle's value. Watch / 🔴 Scrap Threshold: Evaluate the vehicle's overall condition. If the lowest viable replacement cost exceeds approximately 60% of the vehicle's current market value, evaluate scrap value before committing.
Our Recommendation
Our Recommendation
If your i20 petrol engine only rattles for 2-3 seconds on cold starts, book a preventative chain kit replacement immediately. The labour is significantly cheaper when caught early. If the rattling is continuous, accompanied by loss of power or an engine management light, the chain has likely jumped. At this point, internal damage is almost certain, and a rebuilt unit with an updated tensioner is the safest and most economical choice, provided the car's body and interior are in good condition.
