Re: Major smoke out of exhaust

my money is still on the PCV letting oil into the intake. When its parked on an incline, the oil pools to the back of the intake and then is sucked into the engine at startup. A good cleaning of the intake and then a good catch can would fix that.

Then Chrysler should be doing that, not their customers.

Had my PCV changed twice and installed a catch can and mine still smokes.

I had installed a billet technology catch can on my diesel. Though the catch can caught 90% of the oil, i was still finding oil in my intake. I had to have the container modified to accept 3/4" fittings and 3/4" hoses to improve flow. I think that now i'm catching 98% of the oil.
Your gas engines may also still be getting some oil in your intakes, even with the catch can.

I also have the Billet tech catch can. I would think that more flow would result in more oil getting past the can. The opening in the manifold is still 1/2" so increasing the can inlet and outlet would be moot unless the manifold was also modified.

we are a bit off topic now. so the mod can delete this post if its not appropriate.

I'm not an engineer in flow dynamics but here is my experience with the CRD engine in the WK. The air intake is applying a significant vacuum to the crankcase breather valve via the stock breather hose connecting the 2 port fittings. The vacuum pressure applied to the crankcase breather is reduced if the hose connecting the air intake to the crankcase and the associated fittings are a large diameter, this is what I did. I wanted a vacuum, but the higher vacuum pressure of the narrow hose/fitting was actually "vacuuming" the oil out of the crankcase. I enlarged the hose/fitting and this reduced the vacuum and allowed the catch can to do its job and capture the oil mist. I've been running this new setup for about a month and plan to check it this weekend to confirm that the oil reaching the intake is 2% or less.
I think the stock billet technology fittings are 1/2" internal diameter, I went to 3/4" for my test.

On my previous Durango with the 5.9L gas engine, I installed an opaque Fram fuel filter ($4?) in the crankcase breather line, this captures 98% of the oil. When the filter was full of oil, I tossed it out and bought another, usually every 6 months. Fram fuel filters are available with different fitting sizes, there should be one that easily installs on the Hemi's crankcase breather line, much cheaper than the billet technology catch can.
Here is one with 5/16" fitting http://www.summitracing.com/parts/frm-g2/overview/
Here is one with 3/8" fitting http://www.summitracing.com/parts/frm-g3/overview/
I do not know the internal diameter of the Hemi's breather line.

I see your point. The larger opening decreases the velocity of the vacuum and allows the oil a chance of settling in the catch can. Let me know what your results are with the larger lines. The bottom line is that the PCV valve is letting oil get past it and it shouldn't. I never had to modify any of my new Chevy's to stop oil from getting into the intake. Chrysler should make it right.

Re: Major smoke out of exhaust

Modified my oil dip stick to read correctly. I ground off the factory marks and used an engraving tool to put correct full/add marks on the dipstick. Chrysler refused to do anything after they changed the oil pan. It really sucks that Chrysler didn't fix their mistake but I guess thats what you get when you spend almost 50k on one of their products.

Re: Major smoke out of exhaust

Just got off the phone with Chrysler Corp call center drone. She said, she wanted to close my case since I put a catch can on. So basically I am trying to resolve the issue and Chrysler is going to stop. Basically, they are not going to do anything about this smoking issue since they don't know how to fix or can't come up with a solution. Sad day to be a Chrysler fan.

Re: Major smoke out of exhaust

Update.
Went almost 10 days with no blue smoke. Startup first thing this morning and it almost completely covered the truck. So, the catch can is not a fix in my case as well. Going to open the can to see how much is in there after 10 days. I guess if it was full that would account for it, but I sure hope that is not the case.
Back on the phone with the Chrysler.

Re: Major smoke out of exhaust

I too have the same problem. I bought a used 2011 JGC Hemi with 26K miles and when I started it on day 2 of ownership there was blue smoke coming out of the exhausts. My driveway is on a slight incline and it only happens when i park my vehicle nose up whether the engine is warm or cold.

I havent called my dealership yet because I want to make sure i have all the necessary ammo before I talk to them.

Was there any resolution to this problem from Chrysler? I have read other threads and it seems like its a pretty common problem and to boot my ac is acting up. Drove back from Vegas yesterday in 100 plus heat and it stopped working...I hear the blower but nothing coming out of the vents...i stopped turn off the car and started it up again and kicked back on..my guess is the AC clutch is going out?.....less than a week of ownership and i have two major issues...
My 2001 TJ never had any problems and going strong with 185K miles....

Love my TJ but starting to hate my GCL.
