I got some turbo wash liquid with my boat. It's made in Japan, I've got a Yanmar engine. Stuffs like $80 a gallon. Anyways I guess you just put it in a squirt bottle and shoot X fluid ounces into the turbo, under load, over a period of Y seconds. Anyone used something similar on their 6.0? Kind of thinking I should clean the vanes but would rather not take it apart.
