01 7.3 has problems

I carried my truck to the ford house and had them diagnose it, said number 8 injector was stuck open, icp sensor was leaking and turbo pedestal needed new o-rings. Replaced the injector (drivers side against the firewall) and icp sensor earlier today and saw no change in anything, still getting a ton of white smoke and a rough idle. It did however start to lose horsepower while running at highway speeds at random times then just as randomly as it lost everything it got it all back. Any ideas on what next?

Take the air filter off of the turbo compressor housing. Wiggle the turbo compressor back/forth and in/out. If there's excessive play, the turbo is the cause of the white smoke. Never hurts to replace the Cam position sensor either; they are about $30 and can cause all sorts of intermittent problems regarding power loss/ stalling. Also, look into injector o-rings. Bad o-rings can cause oil leaks and rough idling/ power loss.

Cam positon sensor
check turbo for play
think about injector o-rings
