I see that replacing the CCV filter and cleaning the EGR valve are not too big of a deal but removing and cleaning the EGR cooler is quite the job. On the Cummins Diesel forum I've read the back and forth of whether or not this is something that you need to do (if it ain't broke, don't fix it vs do what Dodge recommends). Some Cummins mechanics say that Cummins doesn't require the EGR cooler to be cleaned at specified intervals -- only when it starts acting up and needs it.
A number of owners seem to only replace the CCV filter and clean the EGR valve and not worry about the cooler.
Anyway, if any of you have the 6.7 Cummins, I'd like your opinion of whether or not it's worth it to clean the EGR cooler.

My Cummins mechanic recommended replacing the CCV filter and clean the EGR valve. His thought is if the cooler needs to be cleaned you will be getting check engine messages as opposed to "perform Service" I bring him the parts and he performs both services for $100. I can do it myself in about an hour but throw him the $100 bone for all the free advice he gives me.
