Re: coolant overflow tank leak/supercooler leak

I thought maybe I'd try replacing the 0-ring on the coolant overflow tank cap. I can't get my head around why running at high boost would overpressurize the cooling system / coolant overflow tank. My coolant temp gauge runs in the normal range. Please let me know what you found . . .
Could be air leaking into the cooling system in the IC.
Let's say 10 psi coolant pressure one side of the IC cooler and 15 psi on the SC side. A small hole and the air passes into the coolant. No boost and the coolant passes into the air stream.
