I just got my vehicle back from the dealership. The history is as follows. Took to dealership in June with cold start rattle and diesel like tick at 94000 miles. 1.5 months later got it back with laundry list of parts replaced. Got it back and still rattleing. Took it back and 2 weeks later got it back. Engine was smooth. Started cold start rattleing again with lots of other noise like whirring and ticking. Took it back. Under new tsb had it repaired. Now its silk smooth again. Engine now at 109000 miles. Here is parts list. The reason Im posting it here is I know a lot of guys have these 2nd Gen Ecoboost engines in their Raptor or F150. This post will help those guys out when they search on Google.
