Chris,
Having just received my TO4E-50 turbo from Turbonetics made me think to
ask if you were developing boost and what rpms were involved as you noticed
your oil pressure dropping ?..........Hopefully lack of oil pressure has caused
no damages to your turbo bearings but you probably should check yours to
see if the comp/turbine wheel is still turning freely..........If there is any question
it probably should be inspected..........I would not run the engine with the turbo
attached even after correcting your oil pressure problem without assuring that
it is healthy if it were me............FWIW

The engine is off the engine, prop and all in one big swoop. It actually was pretty easy as, since I have labored
over it so often and finally have it rigged as I want it and not just sloppy proof of concept stuff, the process was methodical and only took an hour or two. I hope to pop the pan after work tomorrow.
Of coarse, I will be sure to bore y'all ....share with y'all what I find...or, don't find.

I looked at an oiling diagram, and the thermal pellet when cold dumps oil from the crank back into the sump.
Very little oil pressure would be left inside the crank while cold. Should that gizmo fail, oil pressure would get worse as the temperature goes up. I assume that you replaced the stock piece with a solid nonfunctioning
piece to avoid this kind of failure.
Could be removed if there is enough room in front of the engine.
