Hello,

Just checking to see if anyone has had the same issue, I drove the truck 2 days ago and has been parked, I started it up this morning and noticed a nice blue cloud of smoke for about 7 seconds and then went away. What the &^%$ could that be? it's Sat so taking it to the dealer will have to wait until Monday but would like to hear some thoughts. There is only 3,000 km's on it

Thanks

 

It sounds like to me that oil is leaking past the valve guides into the combustion chamber. When you start it up the accumulated oil burns and smokes until the oil in the combustion chamber is consumed.

 

My 09 is doing that I just noticed today in fact when I was replacing my cmos cameras with ccd camera's my son started it and I was behind man my old 72 doesn't smoke like that. Was scarey, I think I will beat on it for a while and wait and see what happens. Would one of those catch cans stop it? Sorry I have 11000 km's not sure how long this has been going on

 

What oil are you using? I wonder if Synthetic maybe tends to seep past the valve seals more?

 

Not sure what oil is in it, i have not had it in for a oil change yet. I do no that blue smoke is not normal, oil is getting by some how

 

Have you checked your dipstick to see if you are down any significant amount of oil?

 

That has happened to me before. Just a few seconds of smoke. However this happened when it was cold outside. Since then I always look out my rear view to see if it did it again. It hasn't. After it sits for a while maybe the computer richens the mixture so it washes down the cylinder walls?

 

This was 72 degrees farenheit, truck was parked all night and all day till like 6. I use what the dealer puts in, so if their is an issue with oil, their problem not mine. I am not rushing in because they will just say you need your injectors cleaned, that will cost me a hundred bucks and it will not do anything but make them some money. Besides they get cleaned everytime I drive it. LOL Also it is running good exhaust is so far back there, how am I supposed to know it smokes? If it starts to run like crap then it goes in. How can this oil get by you ask, it is like water when you put it in, it must get even thinner, you would have to have like all polished interior engine parts in order to get this oil not to slip by the rings while sitting. Never low on the dipstick, never moves, in fact they over filled by I would say a litre or so by the stick, called them they said it won't matter, I said mark it down on my file that I called on this date and talked to you, he said it wasn't necessary, I said I am writing it on my receipt exactly what you said to me, I am also forwarding an email to the service manager, sales manager, and Chrysler customer service, so are you sure it's not necessary? He said that was not necessary he will add it to my file. He did tell me it was normal practice on the HEMI's to overfill? Then make a bigger pan, unless I see it on a TSB or RRT or Recall then I only want 7litres or quarts or whatever. Is there two different filters, like the chevys had a small one for the 350 and a larger one, I am thinkingmaybe cuz my oil filter is one small little thing and its not a mopar it is green i think Wix or something like that.Dealer installed. I think I am gonna demand mopar. In fact I think I am gonna go with I think it's Pennzoil or Quaker one of them there oil companies that guarantees you engine for life if you use it. I would supply my own oil and get the dealer to put it in but they don't take enough money of it still costs like 25 bucks instead of 30. I suppose if I propose to them that I pay ahead for so many it would guarantee I come there or I can get my kid to do it in the driveway.

 

I believe your experiencing detonation. It's somewhat common with the Hemi engines, I've seen from time to time on all four of my Hemi's I've owned. One vehicle I even use 93 octane at all times, others with 89 octane. So I'd rule out different grades of octane fuel out, and different filters probably are not going to change any results. Best definition to explain what's taking place......

Unburned end gas, under increasing pressure and heat (from the normal progressive burning process and hot combustion chamber metals) spontaneously combusts, ignited solely by the intense heat and pressure. The remaining fuel in the end gas simply lacks sufficient octane rating to withstand this combination of heat and pressure.

 

What is happening here is not detonation. Detonation (also called pre-ignition) takes place under engine load... and your engine makes a pinging noise under light detonation all the way up to a loud explosion and your connecting rods breaking under heavy detonation. Detonation comes about under hot conditions, poor fuel conditions, overloading and overaggressive spark conditions. Basically your fuel is catching fire before it should, during the compression stroke instead of the ignition stroke. The piston in which it happens momentarily tries to fight the normal rotation of the engine (the early ignition causes the piston to want to go down when it is supposed to be going up), which can lead to catastrophic failure.

None of these conditions apply at start-up. Even on a hot day with poor fuel you will not get detonation at start-up unless you are running a fuel that has such a low flash point that the air fuel mixture produces enough heat to spontaneously combust at about an 8 to 1 ratio (running fuel line antifreeze - methanol - instead of fuel for instance), none of the needed conditions can apply.
