Chipped Turbo fan blade

I had just put in a new (but used with under 100k miles) turbo in my 06’ 6.0. After test driving it for the first time, I pulled the intake off and noticed the fan blades on the turbo where chewed up like a chew toy after that one drive. Is it safe for me to drive the truck with chipped fan blades? I’m not noticing any driving differences except for slightly higher but not alarming egts. And I believe my mechanic hooked up the oil feed line incorrectly which starved the turbo of oil which caused this to happen yet caused an oil leak on right below the turbo and dripping down both sides of the transmission.

Must have something in air filter assy to go through and damage the vanes if they weren’t damaged previously. Prelubing turbo is necessary or leave air tube off and hold the compressor wheel until engine starts and oil pressure is delivered. Used to do this on my Porsche engines once engine started I’d let go of compressor wheel
More like 100k rpm turbos regularly break the sound barrier. Any imbalance will shorten its life considerably
