'86 5KCSTQ - Oil on Air Filter

["Mark Pollan" <Mark.Pollan@MCI.Com>]

All:

I'm reposting since I haven't heard anything.  Kind of unusual for
this group.  My mail server was upgraded over the weekend probably
some issues there.

Anyway, what are possible causes of oil on the air filter.  I have a little
puff of blue at start-up (probably valve seals?), some oil in turbo=>IC
hose, no play in turbo spindle.

What gives?  How serious is each possibility?

TIA,
