    Hello,

    On my new car with a Roots blown (20%) Keith Black B1, I can see after a run (1/4) as much as 1/2 qt of oil pushed in the rear mounted breather tank (between the rear wheels) The breathers are located at the front of the valve covers with no baffle (I have restrictors in the shafts oiling).
    The engine is a refreshed Keith Black with B1 heads, all new inside. I have machined myself the set of rings, and I'm sure of what I did. The oil is 60W Torco, and the car is equipped with a dry sump system.

    So what you think ?

    The breathers come out the front? Like level with the rocker gear?

    Not leveled with the rockers, they are pointed to the front and bolted to the top of the covers

    We used to get as much as a quart with our wedge. Things that make it worse. Wet sump , with the volume of oil in there , design of breather tank , location of breathers on rocker covers.

    A little oil in the tank may just be a sign that the system is working.
