Unhappy 97 7.3 ps blowing blue smoke eeeeeek why ?

i bought a wrecked 97 PS 7.3 for the motor for my other 97 PS and finally got it home and running and now it''s blowing blue smoke ... under hard acceleration ... could it be temporary since it wasn't running for approx a year i figure with some injectors missing etc... ( had to put it back together .... i sure don't want to go thru the headache of swapping motors just to look like a beater oil burner ... know what i mean any ideas on how to diagnose it properly ....`stuck between a rock and a hard place

btw it''s brand new injectors, wiring harness and glow plugs, hpop & ipr valve, from my old motor ...

as the air got worked out of the system it actually runs amazingly smooth with barely any blowby , none from the dipstick, no oil residue in the breather or turbo ( my old motor blowby was so bad the turbo couldn't suck it in fast to keep it from leaking out the hose that feeds the blowby from the valve cover on the drivers side and oil slick on turbo inlet lol)

thanks for the help in advance

Check the turbo for shaft play... you could be sucking oil under hard acceleration...
