Thing is it will do it when you fire it cold. As soon as it starts you can rev the engine hard a couple times then pure nonbubbly fluid will puke out the dip stick tube on the intake. (this is my toy turned head ache) The 400 turbo is behinde a 500 caddy in my 81 elcamino. I love the thing but its gettin under my skin. P.S. Thanks for the info guys.
