Doing head gasket and studs on a truck(relative) and I found the hot side pipe was coated with a sticky black film inside. Not much to find in the intercooler, but it does start just before the compressor housing in the intake horn. Turbo doesn't have any side play and little end play. It doesn't smell like oil or even really have a smell. Just about the whole drivers side of the block is coated with black power steering fluid. Based on where this crap starts and the fact that the intake horn gasket was a soaked mess, do you think it's safe to assume the turbo is fine and this truck had been sucking in power steering fluid?
