slight blue smoke at start up

Recommended Posts

any common issues with a slight blue (non water evaporation) type smoke at start up in the mornings? Its only for the first 5 seconds of the truck starting up, then it goes away.

 

2014 with around 50k miles on it.

 

Runs great, no issues other than this smoke that has me a little concerned. Im hoping its nothing crazy like rings going....

 

questions? ask away.... thx in advance.

Rings would be more consistent throught the rpm and drive. Intake valve seals would show more on startup.

I recently purchased a 2019 Silverado 5.3L V8 with 3,000 miles on it and my truck smokes very similar to your description. It only smokes on initial (cold) start and is very frustrating. I have been back and forth with the dealership and corporate Chevrolet and continue to get the same response, "this is a normal characteristic of your vehicle." I have continued to give them the same response, "I do not accept this as a "normal" characteristic." I am currently waiting on a second opinion from another dealership and will go from there. But as of right now I have not gotten a resolution.

This is a normal characteristic. I was also worried when I purchased my 2014 with the 4.3 v6. I have been advised multiple times and seen it mentioned a few times that this is due to the direct injection system on the 2014+ engines (v6 & v8).

I wonder if the guys with catch cans notice this... Probably not

Still notice this with a Catch Can. Definitely a worthy upgrade but I don't think it addresses the cause.
