I had a spun conrod bearing (#4) on my stock engine at 21k miles. Truck was never abused and had maintenance done meticulously. Never tuned or any aftermarket parts other than catback exhaust. Ford replaced short block under warranty and been running fine since (32k miles now).
Service manager at the dealer informed me that he had seen this same issue several times on ecoboost engines (not just the Raptor version). What I'm trying to say is, these engines seem to have some inherent problems with lubrication or assembly with respect to the rotating assembly.
