Re: white smoke from exhaust and horrible gas mileage

Just a thought but I would loosely hold a gallon freezer bag (possibly with an outher bag of ice) over the tailpipe when doing it and have the condensate analyzed. Then you would know where it is coming from.

BTW I have seen a ruptured vaccuum modulator do something similar. Did you check the level of the automatic transmission fluid ?

ps blue smoke on startup (and sometimes on accelleration) is often worn valve guides. If it were a six, I'd check for misfires.

Re: white smoke from exhaust and horrible gas mileage

Just as a matter of point here white smoke from condensation would be expected at initial start up not long after vehicle was brought up to temp. Blue smoke should not be expected in the exhaust from a new motor... ever... if you are being told that then they are avoiding the issue. Blue smoke is oil getting past rings, valves or gaskets and will only worsen with time.

Re: white smoke from exhaust and horrible gas mileage

Get you a catch can and that will fix the issue. It did for me at least. Chrysler has no clue or desire to fix this.

Re: white smoke from exhaust and horrible gas mileage

OK I'll do it but I don't know how to configure.... find the PCV valve (maybe under engine cover?) then disconnect the output? Then how did you mount the catch can? Maybe a pic if possible--?? How often the catch need emptying? Hook back up for smog inspections?

Re: white smoke from exhaust and horrible gas mileage

I got mine from Billet Technologies. They give you great instructions. Takes about 20 min to install. I empty it out before a oil change. Normally good for at least 3000 miles.

Re: white smoke from exhaust and horrible gas mileage

Seems like that would be an EPA emissions failure - why they went from vent tubes to PCV valves.

Re: white smoke from exhaust and horrible gas mileage

HtownBB--

Thank you SO MUCH for the information! I see now that the white smoke can indeed come from the passage of oil/petroleum condensate reintroduced to the intake system; as presently designed; further, that this phenomenon is characteristic of all Hemi engines throughout the Chrysler product line. So much so in fact that a product line has been created by (at least) two aftermarket manufacturers (Billet Technology and Moroso) to manage this Chrysler design error.

Billet says that they are "Mopar Performance Parts Approved": not sure however whether installation of the product might void the vehicle warranty.

Final continuing question is why the "white smoke" only occurs, on some cars, only when idling and facing uphill (~10deg incline).

In any case, guess I can at least put the fire extinguisher away and approach the problem a step at a time.

Re: white smoke from exhaust and horrible gas mileage

After they replaced my oil pan and windage tray and finally put in the correct amount of oil, the smoke on start up stopped.

Re: white smoke from exhaust and horrible gas mileage

Still no resolution as of 10/02/2013 and Jeep still has intermittent plumes of white smoke from the exhaust.

I have an open case with Chrysler and I now have legal representation

So far the count Dealership of Purchase (DoP) and New Dealership (ND) is as follows:

1) DoP - Smoking from exhaust - Told new car it is expected during break-in
2) DoP - Smoking from exhaust - Told to change gas stations (water in fuel)
3) DoP - Smoking from exhaust - Told they checked everything and found nothing... asked me keep an eye on it to see if it happens again
4) DoP - Smoking from exhaust - DoP conducts a PCV valve replacement
5) DoP - Smoking from exhaust - regional Chrysler rep now involved & reviews
6) DoP - Smoking from exhaust - I informed them they must 'work' on the car or I wasn't taking it back - Resurfaced heads and new gaskets installed
7) DoP -Windshield wipers not working - reset a control module fixed onsite
8) DoP - Smoking from exhaust - Couldn't replicate so replaced spark plugs
9) DoP - Smoking from exhaust - Couldn't replicate so checked plugs with normal indication on plugs (means not water - conclusion is it is the synthetic oil burning)
10) DoP - Smoking from exhaust - Replicated issue and replaced oil pan - damaged trim and left interior with black grease - DoP denied everything and said Jeep was dirty when dropped off... which was totally false.
11) ND - Smoking from exhaust & Trim - ND replaced trim & flashed BiOS on all memory modules - ND damaged new trim piece (bent in two places)
12) ND - Trim & Ride Selection Knob LED - Replaced bent trim and replaced ride selection knob assembly because of three failed LED's

Car has smoked again since the 12th visit and at this point I am waiting for Chrysler to schedule final repair attempt. If they fail to schedule or if they conduct another repair and it smokes again my legal team is certain if 100% refund + time/damages.

Just waiting while my 2012 Jeep Grand Cherokee Overland with 11,000 miles sits because I don't want to add miles. The most unfortunate part of all this is it has soured me to the point that my purchasing power and that of everyone I can influence will never again touch a Jeep product. Whenever I look at that SUV I feel nothing but disappointment in Chrysler's handling of this process. It is most unfortunate since the Jeep I purchased is superb in comfort, handling, fit and finish. However the total lack of caring shown by Jeep is beyond reprehensible. Once I get this vehicle gone I will likely be purchasing a new TESLA Model S P85...
