Best Way to Clean a used Turbo 700 1988

OK here is the situation. I bought a good used 92 B230FT (106K) from a boneyard and when the motor was taken out of the car they must have laid it down in the dirt because the end of the oil return tube on the Turbo is plugged with dirt (they didn't tape or plug the exposed turbo ports with anything) There is even a small amount of sand/dirt in the turbine area.

Is there an easy way to clean out the oil passage, and the turbine housings without tearing the whole unit down? I was thinking about trying to flush it out but wasn't sure what to use? I don't want to damage any seals etc. But I want to make sure that it is clean before I do the motor swap!

Any help would be most appreciated.

    Wow, that's brilliant on their part.

    First try to remove all the dirt you can from the opening which is contaminated by brushing or spraying with brake cleaner while the turbo is inverted and letting it drain out.

    Mix a bucket of paint thinner and degreaser, then immerse the turbo. Blow it out with compressed air. Do this a number of times and the dirt will eventually migrate out of the oil passages and bearings and it will clean up.

      I'm not sure you'd want to immerse the wastegate actuator - depending on the solvents you use it may degrade or dissolve the diaphragm.

        Thanks for the feedback.

        Actually the wastegate actuator is very rusted looking and I was thinking I might replace it anyway, I wouldn't want to take the risk of it failing, so I may just remove it and try to clean the turbo. Even though I only paid $600US for the Motor/incl Turbo and I was afraid that I was going to have to do a minor rebuild on the Turbo.

        Anybody know where I can get a new actuator at a good price?

        Kevin
