TE44 blowing a little oil

[Hammer231]

I pulled the up pipe this weekend and noticed the throttle body was coated with a thin layer of black grease/oil. There's also a bit of it around the inlet bell of the turbo too. Would this be normal for a TE44 that's got about 40,000 miles on it? Anything to be real concerned about? Just wondering if I should start saving for one of those new GT turbos Actually I've been pretty happy with the ole TE44. If I could get another 40,000 plus miles out of it I'd be thrilled.
