IHI RHB52W Questions





1)Outside of the oil seal, what else could cause this issue, as noted the turbos were supposedly rebuilt and there is no play in the turbo
2)Where is the best place for replacement parts..and is there a point when a rebuild is not possible(aside when there is a completed failure)
3)Is there a direct bolt in replacement for that model that would allow me to use the existing setup?
Thanks in advance
