What head gaskets are on it? can you tell? if someone put cometics on it and the surface was not prepped right they can leak under boost only, so hard to find water leaks because we cant pressure test coolant system too easy...

Had some milk on the valve covers on my 525sc. Pulled the top end of the motor off to check everything. The intake gasket water passages were leaking into the lifter valley. Pulled the exhaust, and heads, checked everything. New head, intake and exhaust gaskets. Been fine since.
