Piston smashed into the sparkplug on 2001 ford focus, engine seized. can be fixed without replacing engine?

if it blew out your spark plug then you have a lot of engine pressure probably from blow by or a broken head gasket between pistons.

Yes, it needs a complete rebuild

i have ford focus ghia 2.0 2002 model and i have problem with the fuel pump sometimes it works sometimes it doesn't.. when i fill the tank petrol pores out, the pipe next to the filter also comes out, how do i fix the problem?

I'm sure you replaced the belt at 60,000 or 6 years what ever comes first. So this is just a freak occurrence. When the belt slips the pistons come up hit the valves smashing them into the head if your lucky otherwise the valves go through the piston. If you are lucky you can replace the head with a rebuilt one but a hole in the position you will need different engine

Hello, I have read about the Keyways in the crank and camshafts shearing off. If you disconnect the Battery and take out a sparkplug, you can turn the engine with a breaker bar. Then put a probe into the sparkplug hole and you should be able to feel the piston coming up in the cylinder. If the piston does not move you can start disassembling the front cover to check the Keyway on the crank.

If the pistons are moving. remove a Valve cover and turn the crank while watching the Valves or cam on the topside of the engine. This will give you an indication if the Cam is not turning. It is not impossible for a Cam to snap so watch to see if all parts the entire length of the cam are turning.

Another potential problem much easier to fix is the Starter bendix. If you only hear the Starter cranking without a load, was the engine turning? The Starter gear could fail and the starter will just spin while the engine does nothing.

Would be interested in the outcome of this problem.

If the piston is stuck out this is due to a seized calliper however a temp Fix is to turn the piston clockwise to force it back in as rear callipers are self releasing so they need to be turned clockwise they will not go stright back without turning. This is due by broken calliper seals although you will temp fix it, It's best to either replace calliper or buy a calliper fixing kit which includes all the seals that need replacing.
Also You will need to Empty the brake fluid out to make it easier to push the piston in it, Then you will need to bleed the whole brake system once fitted back.

no they cannot ,remove the drum because it could be a sticking /corroded pistons in the wheel cylinder holding the brakes on

ford focus zetec engine 1.6 ,then its quite easy to do but one word of caution ??BIG TIME and the the bottom pulley is not on a keyway just a slight taper so do not undo the bottom pulley bolt by jamming a big bar with socket on and turning the starter motor ,as the bolt loosens the timing belt pulley moves and the valves hit the pistons .jam the flywheel up with a small jemmy bar in the flywheel teeth by removing the starter motor,trust me on this i smashed two pistons and 6 valves undoing the pulley bolt with the starter motor

Ford focus can have a timing belt about to break,have it checked,and replace it ,if it breaks,it will not start,and it will cost you.The valves in the engine will be bent if the timing belt breaks.

Safely, take your car on a highway or street ( dry pavement ) with no cars or other persons around. Stop the car,proceed to approx. 20 Km/h. Then push the gas pedal down close to the floor, if the car bucks and chucks change the fuel filter and retest. If the problem is still present, I recommend the fuel pump. Have it checked first.
