I have a 1972 Monte with a 350 that was rebuilt 2000 miles ago. It blows a little blue smoke at idle or when it is reved up. Any idea on what to check for?

 

HAVE YOU RECENTLY PUT A NEW EXHAUST SYSTEM ON IF SO THEN IT COULD BE JUST BURNING OFF ANYTHING THAT WAS INSIDE OF THE EXHAUST OR HEADERS. THIS HAPPENED WITH A 69 DODGE DART MY DAD HAS WHICH HE ALSO JUST REBUILT THE ENGINE

 

At 2000 miles it should be broke in. Blue smoke is a rich running condition if memory serves me correctly. What carb are you running?

 

I vote for the carburator being too rich.

Rich would be black smoke. Blue smoke indicates oil being burned. Were the valve seals replaced with the rebuild?

 

Goes to show you how long it's been since I have wrenched.

 

I am not sure if the seals were replaced. This is what I was thinking it was but want to make sure. I am running a stock quadrajet 4 barrel carb. That was supposedly gone through whenthe engine was gone through. It does run fine.

 

it also could just be it is burning the oil have you replaced the oil?
