renault clio timing belt breakage

[katie03]

Hi
damage as far as I can see is 5 bent valves. Small crescent shaped marks on pistons look superficial. Pistons appear to all rise to same height so by eye no bent con rods I think.
My question is when there is a timing belt failure on a clio (1149cc engine 1998) is the damage normally confined to only bent valves or is piston/con rod damage likely.
Would hate to do a full top end overhaul, only to find that con rods are bent, bad vibration and engine shaking itself to bits.
What is the usual damage as a result of the timing belt failure on this car?

depending on the age of car I would consider getting rid, as every funny noise/knock will always make you worry.

All i can say is it's unlikely to have damage other than to the valves.

Valve guides and seats should also be closely looked at.
I had a similar year and model clio which had a belt failure and did as you are planning to do ,she runs beautifully again.Good luck.

unusual for terminal damage to rods and pistons through belt failure damage usually confined to bent valves as the weaker component

[dm1982]

the usual damage to most cars is bent valves when a timing belt snaps, there are some exeptions though

repairing all the damage you see,would cost more then buying a seconhand engine for the car.

Hi, Taking into account what you have listed, the head will be damaged, the piston crowns will more than likely have hair line cracks in them & will not be noticed until the engine is under pressure, Quick & cheapest way out, a replacement unit if you intend to keep the car or sell it for spares, but don't forget to inform DVLA.
