Question about 2004 Ford Focus
My neighbor has a 2001 Ford Focus and when she tries to start it a loud knocking noise seems to be coming from the top side of the engine. Also you can see the engine shaking more than normal during that time. It seem like the car wants to start but struggles and dies out. It also sounds like there is something metal bouncing around in the top of the engine. Any ideas? Thanks!
This can be a serious problem, sounds like one of your engine valves, has the car overheated recently? if your valves bent, you need to take the engine apart hope i helped

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.
