Coolant issue with turbo

Hotrodz

I was jumping for joy when I thought I may have blown head gasket. My coolant system did not get purged or burped completely and it would back fire violently and the car would go into limp mode. A mechanic at the track pointed out that it look like coolant coming from the exhaust. The first dye test should a slight leak. I then did a compression test on each cylinder and there was no leak. Seb purge the coolant system again and said he had a hard time getting the air out of the system and he did another dye test and all was good. He sent an oil sample to Blackstone and it should slightly elevated levels of phosphate and so fast forward 8 months several track days and the motor is as strong as it has always been. Yeah, I jump for joy every time I drive the car without visiting a auto shop after a track event. $1K for the fix beats $7 to $8K for a rebuild.
