Oil leaking from turbo

[Chamberpains]

I used to use degreaser laundry soap for flushing out CAC's. It doesn't have the foaming agent in it. It cut down on the mess in the shop. But if your outside, Dawn dish detergent is your friend. The surfactant helps to lift the oil off the inner surface on the CAC to aid in getting the crap out of it when you flush it with water.
