I DIAGNOSE & FIX MY BROKEN FIESTA ST180! *CRACKED CYLINDER HEAD*

Welcome back all,

This video was not one I expected to make but we have to deal with issues as and when they occur. Once we broke down and finally got my Fiesta ST180 home, I could have a good look over the engine and diagnose the fault. At first I was puzzled as to why the spark plug no.4 was loose but I revealed the cause later in the video to be a cracked cylinder head.

Stripping the cylinder head from the engine block involved removing a lot of parts! This modern engine isn't like the basic old ford engines and has a lot of sensors and wires that control the vehicle. Finding a replacment cylinder head proved harder than expected as I couldn't just buy a bare head and build it up with my valves/cams from my original head. I eventually bought a second hand cylinder head and had that skimmed/cleaned by Chris at Clump Fab.

Rebuilding the engine was fairly straight forward. I had already timed up the engine and decided that now would be a fitting time to replace the cam belt, water pump etc. Once all back together I filled the engine & gearbox with oil along with re-filling the coolant. On the first start up the fiesta didn't run properly and the engine wouldn't rev up. After a look on my diagnostic tool I realised I hasn't reconnected the plug for the throttle body and once that was plugged back in the ST180 ran perfectly!

That's a job jobbed!
