According to the dealer's "diesel specialist," the CCV filter is saturated with oil, causing oil to enter the turbo, intake, emissions/charge, and boost air systems. He recommends replacing the CCV filter, inner cooler, and charge hose. He also recommends cleaning soot and debris from the intake and EGR system, replacing the fuel filter, and possibly replacing the "clogged EGR and cooler." (The EGR was just replaced three months ago). Finally, he says that the throttle does not appear to be operating as it should, and eventually needs to be replaced to the tune of $1,220.
As for the results of the emissions test, the opacity reading was a whopping 62.9%!! You are correct that the federal opacity standard is 20%. I was watching the tail pipe as they were running the Jeep on the rollers and saw a little black smoke at times, but it certainly wasn't what I would call really dark exhaust.
Ok, "Diesel Specialist" in this case is code for "Hose job Specialist". The CCV valve is not a filter. It has some condensation media in it, but it is not a filter. They are all loaded with oil within five minutes of leaving the factory. This is the reason that we all have oil in the intake system. Why on earth would the intercooler need to be replaced? I haven't known of any with holes yet. If the CAC hoses are sweating oil, then yes they will eventually need replacement. Possibly one of them has a small leak now which could be causing a slight power loss and darker than normal smoke ( a big tear is instantly noticeable). For less than $200 and in less than an hour, you can replace them both yourself but the job is very messy. As for cleaning the intake gunk; just clean the MAP sensor. If you get a GDE tune the EGR will be disabled and gunk will no longer be a problem. The oil coming from the CCV is harmless in itself(except to the original hoses) but when it mixes with the soot from the EGR, you get gunk. oops I have to leave for work, more later....Ok I'm back.
Replacing the fuel filter is always a good idea and costs $30. If you don't have a CEL lit up, your EGR is functioning just fine. How he figures that the EGR cooler is clogged is a real mystery and should be in a museum as the first one ever to clog and leave the rest of the cooling system untouched. As a "diesel Specialist" he ought to know that no Diesel engine in history has ever had a "throttle". I wonder if he is referring to the FCV which costs no where near $1220 to replace.
Get away from that dealer and either fix it yourself of find a real mechanic. I will let someone else find the links to the step by step instructions to CAC hose replacement, MAP cleaning, fuel filter replacement, lift pump install, etc because I've just worked all night and want to sleep.
