Are the belts to the water pump allowing it to turn in the correct
direction?  The third generation engine water pump turns the opposite
direction from the second generation engine water pump.

Thanks for the input rusty.  You are very right about other eyes.  Every
interested pair of eyes on the field has taken a look including 2 A&P and a
couple other rotary enthusiasts.  There don't seem to be any problems
staring me in the face. 

I don't have it on this computer, but I did post a pic of my pump.  Nothing
special.  I just lopped off the thermostat area from the first coolant
sensor outward and had someone weld over the thermostat bypass then weld on
a plate to which I bolt an AN-16 Fitting.  This AN-16 fitting goes to the
top of the RAD.  An AN-20 fitting comes out of the bottom of the rad back up
to the pump intake.

The Turbo is plumbed via the stock water supply on the intake manifold, then
goes to the drain fitting on the bottom of the RAD.

The surge can is hung on the PSRU and is connected to the small water outlet
on top of the Rear side housing.  This is a small surge can with a 16# or
20# cap.  Overflow from this can goes to two medium sized (1 qt each) cans
hung in series on the firewall.  I can put a cap on the last on of those to
create an "air spring."

I put a 30# cap on the radiator to effectively seal it off, But I can use
that cap to make sure Air is purged from the rad.

I will make a drawing if this dosen't paint a clear picture.

You guys have the best eyes for solving this kind of problem.  Its really
your input I need.  

In fact, I will make a drawing now.

Thanks,
Dave Leonard
