so far its looking like the GT42 is the culpret. Pressured all cylinders 3 times no bubbles in bottle. Bypassed the turbo lines after all coolant was blow out so far its not doing it anymore. God is good! Kids went for some fuel to see if we can fix the fass system. Thanks Trent, I was questioning everything I did and really forgot about the turbo. We will keep testing for a few days to make 100% sure and then see what we need to do.
