Achieving high levels of refinement has been a key priority in these latest Civic models and NVH measures include an engine undercover, thicker urethane foam insulation in the front bulkhead area, thicker floor mat insulators, and noise-absorbing felt backing on the fascia. The engine itself features a high-performance acoustic cover and a dual damper-type crank pulley, while a higher inertia flywheel further improves refinement levels. ................. Obvioulsy less noise also equals less vibes that the crank withstands, obviously you guys would know better if it was reliability or NVH that drove the duratec change.

"There is hard evidence though, of blown engines due to oiling failure"
Bradness, that was my question - what exactly is that evidence? I mean, how do you know it was oil related failure (as opposed to chronic effects on bearings by crank whip)??

Once again, we have healthy disagreement. I can't comment on what the internals of an engine run without a damper and blown look like. Maybe Puppy is trying to say that it looks just like an oiling failure-that wasn't clear to me from the argument he put forth. However, I do know what a motor that has been starved for oil looks like when torn down.
Again, my experience with my 95, purchased new, with lots of miles has been no such failure! I'm talking about "real world" testing, not in a dyno cell. How many people have UDP's on their motors? If the stock damper is such a piece of crap and UDP's are sooo much worse, then..... Look at the available real world evidence and what do you see?
I'm not trying to sell anything or twist your minds. If you feel more comfortable replacing the single mode or UDP with a dual mode damper, do it! I, for one, remain unconvinced.

Wonder how many qts of oil stay in the heads of the 3.0 Duratech?,how many Taurus 3.0 have failed with oil stravation?,funny as the oil system is the same?why put in a 3.0 when you will have the same problems as a 2.5? FWIW the duel mode Ford of Europe dampers are 'in the air'!!!
