The Vauxhall Adam's petrol engines - predominantly the A14XER 1.4L and A14NET turbo - are generally reliable but known for timing chain tensioner wear and carbon buildup on direct injection units. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure point, plus a minimum 12-month...
Timing Chain Tensioner Failure
Most affected vehicles
Vauxhall Adam Jam, Glam, Slam (2012-2019, A14XER 1.4L)
Failure mileage range
60,000-100,000 miles
Typical failure window
Root cause
Original tensioner design loses pressure over time, allowing chain slack that causes rattling on cold start and potential jump timing.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Preventative Chain & Tensioner Replacement | £800 - £1,400 | £500 - £900 | Replace timing chain, tensioner, guides and seals before failure occurs | Viable if caught early before chain jump; prevents catastrophic damage |
| Full Replacement - Rebuilt / Reconditioned Engine | £2,800 - £4,200 | £1,200 - £2,400 | Supply and fit rebuilt A14XER with upgraded tensioner, bench-tested, 12-month warranty | Best value if engine already damaged; eliminates repeat failure risk |
Our recommendation
If you hear a cold-start rattle but the engine still runs smoothly, a preventative chain kit replacement offers better value than waiting for failure. However, if the chain has jumped or the engine won't start, a rebuilt unit with upgraded components is the only reliable solution for a car worth £3,000-£8,000.
