Wastegate backflush kit
Has anyone made up a backflush kit for cleaning out the wastegate actuator... especially the restrictor orifice on the inlet side of the TSIO-360C/CB's?
Sometime way back on Peter's old message board, GMAs referred to it a couple of times but I never did see a parts lists of components needed to do the job. This is a must-have item for those who have high-time turbocharged 360's because of the carbon buildup.
Cessna could have helped the situation by taking the oil from the other side of the filter, but the way things are set-up the inlet oil line for the wastegate comes off of the pump side before it goes into the filter, so all the dirt and crap makes it into that little orifice. Not a problem on new engines, but when they get older this becomes a major pain in the behind because any tiny carbon flecks generated from the oil squirts on the backside of the pistons are instant candidates for blockage of the actuator... especially if there's been infrequent use of the plane.
