Yeah...I like the idea of the 2.8 CRD. With a little boosting, some engine work, and some other mods, I think it has a lot of potential. As for the 3.0 CRD, there are some places that have rebuilds available. A little pricey, some where in the $5,000 range. So what are these problems with the 3.0 CRD being aluminum and over-heating? The Germans have been building diesels for a long time so I would have to think they would have simple issues such as "over-heating an aluminum block" solved. And the Mercedes people yet? If the engine is "sleaved", then I would think it would be ok, but....
I guess it is a little early yet to know all the problems with it.
Hmm....
