I'll let you know that this dealer says.
Bull pucky, it's not a film that builds up in transit. When I took mine in for the same issue last week I made sure to have a conversation with the service manager about it. I offered video of my vehicle proofing out the "oil" smoke, and suggested he research it online, which he did. He also contacted Chrysler for guidance. Chrysler IS aware of this problem and had the dealer replace the PVC valve, which is their standard plan of attack for this issue at this point. Changing the PVC valve does not and did not correct the smoking but we didn't really expect it to. The service manager told me that it may be caused by a faulty part or an error in design (most likely I think) and that Chrysler engineers are working on a fix for this but it may be awhile. There are many threads about the issue on this forum and the other jeep forum, I suggest reading them all. And most of all, GOOD LUCK AND if your dealer pulls off some kind of miracle and manages to fix it be sure to let the rest of us know what they did!

Re: white smoke from exhaust and horrible gas mileage

Not surprised, they didn't find anything wrong. Couldn't replicate the problem and it didn't throw any CEL errors so apparently there's no issue. Whatever.

Oh yeah and the funny part is, they took the car on a 20 mile test drive (not sure how I feel about that) to ascertain the MPG issue. The guy tells me that it clocked an average 18 MPG (all highway mind you). However, when I jumped into the vehicle I saw the EVIC numbers and it read 12 miles for that particular run. Underwhelmed by this dealer.

Re: white smoke from exhaust and horrible gas mileage

My V6 gets 12 MPG (I have 5,000 miles on my WK2) during my "regular" driving cycle in NYC (infrequent short trips that often end soon after engine warmed up). On highway I get 23-24 MPG, during longer drives in the city - 15-16 MPG. So 10 MPG with HEMI doesn't seem abnormal if the driving cycle is mostly short city trips, and hills sure aren't helping.

Now if you say you sometimes get 8 MPG this does seem too low even for HEMI. On my old '98 ZJ with 5.2L V8 I never got less than 10 MPG in my city cycle.

Re: white smoke from exhaust and horrible gas mileage

For my third tank of gas I filled up at Shell (89 octane). The first two tanks were with Mobile. I've only gone through about a 1/4 tank so far, but it appears my MGP has improved a lot. Too early to call it a success, and I'm somewhat doubtful that a different gas type can make that dramatic of a difference, but I'm optimistic.

Anyone else have success with certain brands of gas?

Re: white smoke from exhaust and horrible gas mileage

My 2014 JGC Hemi Limited does the same thing; belches bluish smoke when starting up even on a very slight incline. Dealer says STAR is telling them to keep overnight on incline, then drop the pan and remove half of the mechanism to see if they can solve the problem. Guess I will do it because the smoke has to be a problem brewing. Mileage is 18-20, so that hasn't been affected so far.

Re: white smoke from exhaust and horrible gas mileage

I am working with my dealer as well. I installed a catch can a few weeks back hoping for a fix. It has not smoked since then, but I am still waiting. Dealer and Chrysler has not clue on how to fix this issue yet.
Some people have the CC and it still smokes.
Have you opened a STAR case with Chrysler yet? if not, do. I am sure you will get the same thing I got, "No we have not heard of that issue before". But if enough people open cases maybe someone up there will take notice.

Re: white smoke from exhaust and horrible gas mileage

2012 JGC_Overland
Under 10,000 miles

Seven (7) visits to the dealer about white smoke from the tailpipe. It is not happening at initial start it is happening LONG after the vehicle has been running and is at standard operating temprature (at or just below mid gauge). Sixth incident happened while I was volunteering at the Avon Walk and delivering supplies. Had the back open while unloading water at an aid station and CLOUDS of WHITE SMOKE came pouring out of the tailpipes. This had happened before so I wasnt freaked out but everyone else was screaming for someone to shut off the car cause it was on FIRE!!... I am stating all of this so folks understand the quantity and how startling the smoke was in this situation. So to be clear what I am experiencing with my car IS NOT a condensation issue... the smoke has a odor but it is tough to place. It is WHITE not blue.. not black... not orange with pink poka dots... it is WHITE and comes out in small or large quantities and does not replicate in any discernable fashion. On my 7th visit to the dealer I handed them the keys and said I wasnt taking the car back till they had found something and done some sort of corrective action. On this visit they took the heads off and resurfaced them to ensure they had perfectly level surfaces even though they measured in tolerance. They replaced all the top end gaskets and gave me back my SUV. Roughly two weeks have passed and we have had our 8th incident that I have been able to document on video. I am in the process of seeking replacement with Chrysler/Jeep and I will let you all know how it pans out. If I am happy with the process and terms they put forward then I will work with them... otherwise I guess I will have to lawyer up and take this to task. $50K+ SUV shouldnt be doing this and this is an issue that is happening to frequently to other owners from what I have been reading for the corporate stance to be isolated instances. BTW I am pressing for a new replacement and not seeking some sort of monetary settlement. We love our Jeep products we are just having a bad experience with this one... I hope

Re: white smoke from exhaust and horrible gas mileage

WDC,

Have you had to add water after this happens?

Re: white smoke from exhaust and horrible gas mileage

No fluid levels show any differences that I have found. I have been checking antifreeze, oil, and transmission fluid levels this entire time trying to figure this out.

Honestly if it was any significant amount of water it would cause the car to run really rough or possibly even cause it to shut off. So I am wondering if it is a very fine crack in the block along one of the cooling tube/shafts that when conditions are just right (pressure, temperature, cooling/expansion of metal) that it allows a very small amount of fluid to pass and this is creating white smoke... this is all hypothetical but it seems more likely then the myriad of BS I have been fed to date.

Re: white smoke from exhaust and horrible gas mileage

Small amounts of white smoke is normal condensation in the exhaust. The light blue smoke is from oil in the intake/cylinders. Not sure exactly it is. The blue smoke normally a lot and after about 3 seconds start up. At least with mine it is.
