Ok I havent read where the oil is coming from. He just said oil in exhaust
at WOT.
Assuming its coming from the turbo either you are over oiling the turbo, or
a bad
return system. Or just a bad seal in turbo.
I have been running a .030 restrictor in my dual ball bearing turbo (drilled
a set screw
and tapped the inside of the an fitting. Made several different sizes .020 -
0.060). They
dual ball bearing turbos need less oil then a regular bearing turbo.
What size line is drain out of turbo? I have been using a -10an line for my
small turbo
and it does just fine. Even have it return below the oil level which I was
told wont work.
But the honest answer is if I had the space of the header I would return the
oil above the oil level.

Mayf,
My opinion -- again.
TURBO OILING
Supply regulated oil pressure recommended by the manufacturer and
the volume will be correct.
Use Syn. oil and ignore the temperature, BUT remember the oil coming
out of the turbo looks like it has spent the afternoon in a high speed
blender. I don't understand how a turbo creates so much foam, but
that is what I've seen. Maybe it was just my turbo ...???
There must be turbos that don't do that...
OIL PAN
Jack has run on the long course with SBC's and a 8-10 quart pan.
the engines were NA 302-38?. I saw the rod bearings and they looked
used but good.
Jack ran a twin turbo flathead with a large pan and only wiped out the
rod bearings once.
I suspect that turbo foamed oil had something to do with it, but I
couldn't afford to prove it.
Just my 2 cents,
Bryan
