Help protect me from me.
 
Yesterday, I removed all my primary -10 oil lines and checked them for obstructions or obvious assembly errors, but found non.  I removed the plugs ad cranked the engine after injecting some oil into the rotor chambers and a bit (not much will go in from a squirt bottle) into the PSRU.  Finally, I got a small stream of oil coming out of the filter, but nothing to get excited about.
 
I removed the mechanical gauge I had installed with some excess hose on the top of the engine where oil comes out of the stock turbo block that feeds my aftermarket turbo.  When I removed the hose, oil came spilling out of the hose.  This hose had been empty before I installed the mechanical gauge, which had read about 6 psi when I tested it a couple of days ago.  So, "some" oil was/is flowing, just at what seems a significantly reduced rate.
 
SOOOO, unless someone has a Eureka moment to share, I will be pulling the engine off the plane and dropping the pan and likely removing the front cover.  I do seem to have strong compression (I hope my ear is telling me right) thus, hopefully cracking the block open will not be needed and if I understand correctly would not be causing low oil pressure.  I am only a bit concerned of possible damage that may have occurred.  I will check the things I seem to recall being issues.  The key in the front e-shaft, the retaining clip, the pressure regulator, oil pump and whatever else becomes obvious.
 
Again, looking for those Eureka moments that may belay this action.......
 
As always, thanks.
