1. Timing Chain Rattle
Why KA24DE Engines Fail Prematurely
Affected Models
Nissan 240SX S13/S14 (1991-1998, KA24DE, KA24DE-1, KA24DE-2)
Typical Failure Mileage
60,000-100,000 miles
Root Cause
Hydraulic tensioner wear allows chain slack, causing rattling on cold start and potential jump.
Repair Options & Estimated Costs (UK ranges)
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Minor - Preventative Chain Kit Minor | £800 - £1,400 | £500 - £900 | Replace tensioner, guides, chain before jump | Viable if caught early; 40k+ mile extension |
Full Replacement - Rebuilt Engine Best Value | £2,100 - £3,800 | £850 - £2,400 | Supply & fit rebuilt KA24DE with upgraded tensioner | Lifetime solution; 12-month unlimited warranty |
Our Recommendation
Best next step for timing chain rattle
If your 240SX shows cold-start rattle below 80k miles, a preventative chain kit offers best value. Beyond 100k miles or with jump damage, replacement is more economical.
Don't Let Engine Failure Write Off Your Nissan 240SX
Timing chain rattle, oil consumption, and overheating are the most common reasons Nissan 240SX owners seek replacement engines. EngineMarket makes it simple to compare prices from trusted UK specialists who supply rebuilt KA24DE units with upgraded components addressing these exact failure points.
