2017 ford fiesta ecoboost.
Came to me as a non runner and diagnosed as a failed timing belt.
Stripped engine and carried out cylinder leak test and found the valves to be ok.
Replaced both wet belts and cleaned oil strainer. Found inlet vvt pulley to be faulty so replaced with a used unit I had in the unit to save the owner some money.
Once running there was an issue with the throttle module which was replaced with one I had in the workshop.
Rebuilt and running as it should.
A failed wet belt doesn't always mean catastrophic damage. Have done a few of these with no damage and new belt sorted it out. Although prevention is better than the cure it's not always worse case when it does fail. Parts are readily available for these engines including full cylinder heads which aren't that expensive if need be.. it's far better to repair what you have than buy an unknown expensive 2nd hand replacement which you would most likely need to fit a belt to as well increasing the overall cost.
