Project Truck Turbo MkII, gathering dust

[ozonehostile]

revving it stationary with no oil wont cause the turbo to have raping play....play only occurs over time / abuse...all that will happen with no oil is itl seize...I seized the turbo twice on my blown transit from the hose pipe oil feed failing out field on FULL boost at 40psi..just got it turning again with a deep socket, got oil feed up again, and ragged on, never failed / play never got worse of such!

I'm just curious how it went from zero play to lots and all that's happened is being ran dry and revved enough to leave soot stains on the floor :-\
