We are working on the D-8R sn# 7XM2565 doing a bunch of stuff to it. The main problem was the turbo broke the shaft and the cold side impeller exploded so we had to pull the cover off the aftercooler to get all the parts out. The exhaust manifold had 1 broke stud so we pulled it off to reseal it, every single one of the rest broke! Anyway the reason for this post is to see what opinions on the sleaves that slide in the exhaust ports are. Should we replace them or leave them out? I don't really know what the point of them is and have seen two different C-15's loose turbos when they start breaking up and sending chunks down stream. SIS doesn't show them for this motor but it had them in it.
