DaimlerChrysler has already improved the 2.7, in 2001, they strengthened the timing chain to resist breakage. They also changed the oil pickup tube so that it won't clog up. In my opinion, it's a problem that's weather/climate related because here in FL, most of my colleagues, not just at my dealer, but most other dealers around here have NEVER heard of the 2.7 engine failure. In fact, the only one I've ever seen fail was a guy who went 10,000 miles b4 his first oil change and ran low on oil.
