I have purchased my Ford in 2004 and its running smoothly upto last month and now it making some noisy sound and stop while running.
Mechanic says engine crashed , why this happens..

The type of noise, where it is & specifically when does it happen are needed to estimate what broke.
I'm not familiar with the term crash, my best guess is that maybe the timing belt has jumped a tooth & the valves where hitting the piston heads. As it has now stopped all together, the belt has broken or slipped further.
If you are lucky replacing the belt might work, otherwise its the head off, repair recondition as needed.
Without more info I can only give an opinion.
Hope its an easy & cheap fix
My Timing belt failure happened out the blue and stopped the engine like yours. We got away with a reconditioned cylinder head, not cheap £500 to fix, but better than a new or recon engine!
My fingers crossed for you!
Car noise can be caused due to many reasons like rubbing of parts, damaged crankshaft, timing chain, transmission and others Generally a ticking noise is caused by low oil pressure. That can be resolved by a mechanic who will check oil pressure. If low oil pressure found, it is most likely a clogged pump or the pump is starting to fail.
This information i have collected from online expert pages like hiperformer, wikihow and wikipedia pages
Just for your referance of how a 4 stroke works
1 induction stroke (suck) inlet valve opens as the piston is on the downward stroke to suck in the air/fuel mixture.
2 Compression (squeeze) all valves closed as the piston returns on the compression stroke.
3 Power (go) all valves closed, the spark plug lights the air/fuel ( or it self detonates if diesel) and the contolled "explosion" push the piston down the barrel.
4.Exhaust. (blow) As the piston starts to return on the up stroke, the exhaust valve opens to let the burnt exhaust gasses out
Then the piston back at the top & the whole cycle repeated
Easy way to remember is
Suck- Squeeze-Bang-Blow!
In order to get the best efficency, the highest compression ratio is designed for ( volume in barrel at the bottom divided by volume contained with the piston at the top). This means that the piston has to get very close to the head & its valves. So if the valves are left open eg by belt slip or failure, the piston will crash into them.
When I buy a new to me car & it is not certain the timing belt has been changed at the service time, I get a new one. I have had one fail early @ 40000 of its 50000 (year 4 of the 5 permitted which ever comes first) so you can be unlucky too.
I give this to you so the garage will not try to fool you with extras!
