So I was on the dyno yesterday, on my 3rd run the truck puked out coolant thru the overflow tube. Once I got off the dyno it was no longer coming out.

I removed the cap and noticed there was some pressure under it, and my coolant had bubbles in it. Pulled a sample of my coolant it looked dark green.

I'm sure I popped a gasket, but with ARP 425's and only 65 psi boost? Doesn't seem like it should have..
 
If you can find one get a tester that is liquid filled and changes color with exhaust gasses we check 6.0's that way.
