I have had a coolant problem since I got this engine back from Turintine. It
would bubble out of the block as I came back from flying.

I added stop leak and have been flying since.

It did boil over on one 90 degree day, but I took the bonnet off and it
cooled right down.

I will send the block back to Bruce soon.

Jerry, What do your rad ducts look like? Got any pictures of the rad ducts?
Are you using cowl flaps? What does the outlet area look like?
Is there a radius on the firewall near the outlet area?
