Todd,
Is is white smoke or blue or both and how long will it do it before it clears out. White is generally water related while blue is oil related. Is it still running smoothly? I would pull all 16 plugs and see how they look to start.

I know its under warranty so you may not want to do it yourself.

good luck, Salty :eek:uch:

If white/blue (water/oil) my guess would be head gasket related, or worse yet a warped head. If blue only, and only after sitting for a while my guess would be valve guide seals. At any rate, get it in to your dealer.

Todd, you don't mention any CEL or whether you checked for codes, but I concur... not only would I get it to the Dealer ASAP, but I would have it towed there.

Good Luck :nervous:

No doubt, if there are 25 mysterious miles on it, and rubber has to be cleaned off of a once clean quarter panel, then that's just ridiculous. Hope it all works out well, sounds like it's burning oil somewhere, and given that it's after it sits an hour is when it does it, sounds like it may be heat related.

Let me first say that I feel your pain. I've been there before and I don't want to be there again.

That being said, I can't remember those 20 days that my car was in the shop. The enjoyment I've had since then far outweigh the time away from her.

Get her to the shop and stay on top of everything they do. Try to work with the head of the Service Department and if they call in the Regional Service Rep get to know him very well. He's the one that can make things happen. I would also suggest requesting a complimentary extended warranty depending on how long they keep the car.(I got a 7/75 Maximum Care on the house).

Good luck!

I remember your post back when and this extended care is part of the list I am making. I have absolutes on what they need to do immediately. Once I have these absolutes done, I and they should know what general area the issue is coming from and then I have a new list they will get presented with and it includes the complimentary extended warranty. The car will be headed their way tomorrow and I want to personally see all the plugs and they better be labled what cylinder they are from.

Todd, that sucks and I feel your pain. I know when I worked at the dealer we drove cars more than we should have and in some case beat the piss out of them. I hope this is not the case for you. It sounds as if your going to need some engine work either way.

Did you check the coolant to see if it is low can you smell emissions in the coolant bottle? Either way we will know more tomorrow

Todd,

Not good, not good at all. Let us know what you find out and what happens. Also be sure and collect the names, addresses, telephone numbers and E-mail addresses from the principal players at the dealership in the event your 300C Forum family needs to weigh in!

Good luck and so sorry.

Man, I hate that for you. Sounds like they rode it hard and put it up wet. THere needs to be some heads rolling there and probably will be when they have to pay for this.

Todd a little diagnostic help for you


Grey smoke from the exhaust when you start your car
:
The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it.
Possible causes:

1. The engine's piston rings may be worn or broken, piston may be fractured/cracked
2. Damaged or worn valve guides: Replace valve guides.

White smoke or water vapor from the exhaust:
If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem.
Possible causes:

1. Cylinder head gasket(s) may be bad: Replace cylinder head gasket(s).
2 Cylinder head(s) may be warped or cracked: Resurface or replace cylinder heads.
3. Engine block may be cracked: Replace engine block.

PM me if you want to do a compression test, and/or a leakdown test I will give you some more info.

Dealer should be able to diagnose this quickly (Same Day).

That was the first thing I thought, bad piston/ring, I really hope that's not what it is.

Todd Some questions that you might be asked

What mods have you done to your car?

What oil are you using?

Oil Viscosity Issue???

Seems to me your the guy who went with Amsoil 5W-30 at 1100 miles NOT the Mobil 1 0-40 it calls for. Your reasoning was the heat in Texas. I don't know if your aware of it, but that engine was tested in Death Valley, probably a lot hotter there than where you live. You just may be in the hurt locker if it comes to a warranty claim. Good luck.

Actually I just found your post from 15 Jul:

"No, I am not running Mobile 0W-40. I am running Amsoil 5W-30. It is much hotter here than I wish for a 0W oil. Even with modern additives, I still believe that the oil weight must attempt to match up with the enviroment the engine is operated in. The Amsoil exceeds all of DCX's specs, so I am going to stick with it."

Rambit has come across an important point.

Apart from not being a factory recommended oil.

Your assumptions about oil are flawed. Your theory about 5-30 being more suitable for hotter climate is incorrect, at engine hot temp the oil acts as a 30 weight - thinner and less protective than a 0-40 which acts as a 40 weight engine hot.
