After putting my car back together im getting a clear colored smoke coming from the exhaust, Smells like burnt oil, and it seems to be drinking all of anti-freeze and spiting it out because the radiator is full when i check it, then i check it later and its empty and my car is overheating but its not leaking out, i just put new heads and new head gaskets on it but im afraid i might have blew another.

What year? What engine?

last time i changed a head gasket (few months ago on a saturn), i had white smoke coming out for ~30 miles, then stopped. But it only used up a few ounces of coolant. Yours sounds like it didnt seal properly

1994 350 5.7 LT1 i had the heads put on professionaly, although they still could of sealed bad like you said, it only smokes when i first start it or really step on it.

Did they check the heads and the deck for flatness?

Did you "burp" the coolant system after the engine was rebuilt? If not, this could explain ywhy your coolant level is down and you're over heating.

dumond123

yes, heads and block were checked, and yes it was burped, now its not overheating anymore but its still smoking, its really white and you can only notice it when i come to a stop or idling or stepping on it. Really want to figure it out.

Sounds like you need to bring it back to where the heads were installed...

dumond123

well it was a family friend who pretty much did it for free so im kind of on my own from here.

He might be able to help though, you dont want to ruin the car!

How difficult to change the head gaskets? Never pulled a motor apart. I consider myself mechanically inclined though.
