is it normal for some blue smoke to be seen at cold start ups?

 

mine does the same thing
i dont know if it makes a difference that i have 200 cell cats ..

it alsodoes it occasionaly on warm start ups as well

 

seen white,but not blue, flat sixes are infamous for it.

 

so a little blue smoke is not normal?

 

little smoke wont hurt

 

it's happened to me a couple of times. mostly when it's been really cold out. engine seems to run fine. it's just once in a blue moon that it happens.

 

I talked to a tech last time I stopped at a dealership and he said that a lo of time, oil/sludge puddles in the intake hoses right past the turbos going into the intecoolers. He said it's a good idea to drain that once in a while. Also , when doing an oil change, also empty the reserrvoirs under the turbos as sludge likes to puddle in there. Don't know if it will make a difference but just my 2 cents.

 

just a little embarassing when u have someone over and wants to see your car then u start it for them and a puff of blue smoke comes out and fills the garage..

 

+1 on that! lol!

 

that's special imported German smoke. Don't you stress how rare that is to your lucky guests.

 

I always tell them it is like a fine cuban cigar

 

Mine does the same if I don't drive it for a few days.

 

Mine does it also, but seems to be more prevalent when I park on a slanted grade in my driveway-
If I park in my garage and sit for about 60 seconds prior to shutting the engine down, it does not puff the smoke.
Not sure what the correlation there is but it seems to matter-Bottom line that smoke is priceless (I am coming to that realization very fast).
Wouldn't have it any other way-

 

mine did it once today I started my car probably 10 -12 times throughout the day.

 

Well, as far as parking slanted, my BMW bike does the same thing, and it is also a boxer engine setup. They do call the bmw bikes oilhheads as the oil pools in the heads and that causes the smoke.
