The 3.5L Eco sounded like a massey fergueson tractor one morning. I guess I got the infamous cold knock problem. Dealer said it would be a week to look at it, I always wanted a diesel so I traded it in.
Yeah, I never have been a fan of the 3.5 liter ecoboost motor even in high boost applications. That is no good that the truck rattled like that and many Gen2 owners have had bad problems with them.
