broken distribution

How long .....
oooooh ... it seems that the distribution strap has broken. They tell me in the workshop that has destroyed me the 16 valves and that it brings me more to replace the engine with one of scratch in good condition.
Now. I have read that there are engines with interference and without interference, in the latter they say that it stays at a point where the pistons do not double the valves.
What's true?
The engine of my megane 1.4 16V of the year 2000 How is it?
As always thanks and greeting to all.

Hello, what does that of interference mean, what I can be that if you have broken the distribution strap almost certainly has folded valves, it also depends on the times you throw at the start at the start. The Renault engines usually fold them and if it is possible that it has folded the 16.

We are crazy or what? Go and run out of that workshop.
That engine does not have almost an explosion camera and yes, you open all the valves but a set of labor valves and at most a valve seat that in that engine does not break because they are very small valves you get about 1000 euros new belt And the car is new.
Dasting engine 1,500 euros carrying for the cheap more labor to change it 500 euros nobody frees you. More than you don't know the kilometers that this engine has or if you have to put on a strap to that engine or something else.

Changing valves only if the mechanic that opens the vehicle sees it very badly changes cylinder head or plans and gets much cheaper.

same problem: the last time I opened a megane only broken 12 16 valves changed the joint joint and the car today sounds perfect.
