I have a Mk4 Fiesta with a 1.4 zetec engine. Was driving it home today and it just cut out. Checked the usual and then the cambelt. I am assuming one of the tensioners has gone, as the cambelt is all loose. Prior to discovering it was the cambelt I did try turning the engine over a few times. What is the worst and best case scenario???? Gutted as I only bought it today!!!

 

worse case bent valves mate

 

Cheers, take it will be best for me to take the head off and check and go from there?
