Hi,
The primary reason the original rings are replaced with viton ones is to ensure there is a proper seal so when you are on turbo boost this is not wasted and thus power output is reduced, the original rings swell in oil!!, and fall off into the intercooler, so there is a leak, so when you put your foot down oily deposits from the exhaust gases are blown off all over the large boost hose that goes from the EGR valve to intercooler.
incidently, when this hose is leaking you should not get blue smoke from exhaust, usually this will be from a blocked PCV valve filter or very rarely a blown turbo seals ( very rare in diesel 75!).
