Mostly, but the failures still intrigue me. Especially when they are occurring so early in the ownership of the vehicle.The 2.7L is a fine engine, most of the bashing is coming from people with 2.3L buyers remorse.
I am convinced that there is something that is a consistent factor in the few documented that have blown up. All appear to have died when not being flogged.
A bad batch of valves is still a potential explanation. However running excessively lean appears plausible now too, given the visual evidence that looks like pre-ignition/detonation, along with the fact that a failure in the dual injection system could create the circumstances for this to occur under cruise conditions.
