Trafic 2.0 dCi M9R Timing chains are allegedly a "Fit for Life" item. Unfortunately the "small print" deems this to be 100,000 Miles (160,000 Kms).
Should this fail, the result is catastrophic, in damage to both the engine & wallet.
The pictures show the damage to my 146,000 mile engine, in which, I consider myself to be lucky, as it was changed before timing was lost.
My bill was just over £1000 (04/2016 Including Aircon regas & Gearbox oil change as extras).
Had this been done before 100,000 it would have been about £500.
The perceived wisdom, Should the chain fail, is that the engine is beyond economic repair. Worst case:- 4 Injectors, set of Valves, machining, Gaskets, oil, Oil Pump, labour £2600 - £2800 est
My engineer will only fit Genuine Renault parts. (Timing chain Kit £150 + Labour, 2016 Price).
Kit includes a new tensioner & oil feed, which over time gets blocked, accelerating chain wear.
Tell tale signs. A whistling noise as chain runs catch each other. A rattle on start up, till oil gets round.

Pics 2 & 3, Show damage to the Oil pump caused by the broken sprocket teeth dropping into the sump & being "eaten" by the gears.

Notice the warning (bottom left, about possible undiscovered damage).
