    we use closed cell foam and silicone in the corners. It has worked for well on our roots and PSI blowers.

    I purchased aluminum extrusion angle from the hardware store; adapted it to the seal surface on the block; to screw on below the seals and angle backup against the seals on the outside; never had a seal leak problem afterwords.

    We did the same thing after pushing some out during warm-ups at Richmond in 2015. Have not had any issues since. They are visible in this picture:

    If you have access to a mill, make a spacer that bolts to top edge of block. use countersink bolts and make it wide enough to put in an O-ring. No more foam

    ^^^^^^. That's exactly what I did and have never looked back. Thought I was the only one to try that.
