white smoke
 

Ive noticed some whit smoke coming out of my tail pipe recently. My car is an 85 carbureted ss with a 305. It doesnt smell like anti freeze and my power is up to normal. someone told me im burning too lean. I was wondering if this was true and if so how do i git-er-fixed. Thankyou

burning too lean wont make it smoke...is the engine stock? has it ever been apart??

RE: white smoke

RE: white smoke
 

burning lean means that in your air to fuel mixture, you have too much air, and not enough fuel.

yes it is stock and no i dont think it was ever apart

RE: white smoke
 

as a motor gets to be older, one of the first things to go south is valve guide seals...that allows a tiny bit of oil into the combustion chambers, thus producing a bit of smoke. i would keep an eye on the oil level...if you dont already. also, have you felt any change in performance?

RE: white smoke
 

White smoke is generally an indicator that your burning off water somewhere in the combustion process.

I have a few ????? ..

Did this just start happening abruptly?

Is it smoking alot?

There is not much difference between a blue smoke which would be oil burn off and water which would be a little lighter.

Are you losing water from your cooling system?


If it were running too rich your smoke would be more on the black side.

Additionally, I would pull several if not all of your spark plugs for inspection.


Black/Dry: Running too rich.

Black/Wet: Burning oil

Wet/Rust: Water
