If it's what I'm guessing, the 2006-2010 line had valve issues. The seats would break and fall into the chamber, highly likely that the kind of catastrophic failure this would cause could damage the intake manifold when metal flies upwards into it, leaving it to be replaced as well. Mine made it to 108k before this failure, most of them start to break from this at around 75-85k. Mine lasted til 108k, then it was time for a reman. I'm looking to keep it for another ten years at least.
I'm looking to buy a Commander this spring but trying to decide between the hemi and 4.7. I've read some threads talking about power differences but longevity and repair costs are equally important to me. Are the issues you had just on the Hemi?
