Just to let everyone know, I've finally found a scavange pump/oil
combination that works for my TE-06 turbo'd 20B.  The critical clue came
when Main Turbo asked if there was any possibility pump #3 was
cavitating.  Well, probably not, but it definitely was straining real
hard trying to pump 30 Wt. mineral oil.

The solution:  I pumped gasoline through the pump to clear out all
mineral oil, then pumped Mobil1 1-30 oil through it.  It pumped Mobil 1
like a champ.  So I changed engine oil to Mobil 1, and had my first
successful run without white exhaust smoke and without oil leaks around
the turbo.  Looked and sounded great.

Now on to other projects, like finishing cowling details, cabin
interior, etc.  Is that light I see at the end of the tunnel?

Congratulations on solving that problem.

Could be something else going on here? Mobil one does not breakdown until
about 470 F while regular motor oil is only good to about 250 F.
