Hey guys. When I start my car in the morning, some normal-looking smoke comes out at a steady stream and ends after 5 seconds. Is this normal? Thanks.

Depends - hard to say without seeing/smelling it:

1. as it starts to get colder outside, you will see water vapor when first starting it up
2. if you let it site for a while oil vapor (from the PCV) accumulates/condenses in the intake and that will burn off on start up...

So:
1. white or blue?
If blue - you can try putting some oil-seperators on:

2. odor?

yes its normal. its just condensation build up that burns off on the first start.

Thanks. And to answer your question about the color. It's blue and doesn't have an odor. I use Mobil One synthetic oil with a K&N air filter, K&N cold air intake, and a Borla axle-back exhaust. Does this stuff anything to do with it??

My Dad disagrees with fishyducky because the smoke is blue.

Nah - sounds like PCV is leaving oil vapor in your intake which then condenses...

For the most part it is relatively harmless - as are the filters I mentioned. They should stop most if not all of it...

There is no reason that oil NEEDs to flow back into your intake, it is done for emissions purposes - crank case needs to vent - they (EPA/CA) would rather it not vent into open air.

P.S. it is "normal" for these cars to do this, but ifit bugs you and/or you don't wan't your plugs to see a drop of oil they don't need, then get the filters...
